Incoming Call Issue in Vtigercrm using Elastix(Solved )

General approach to fixing Vtiger CRM incoming calls pop-up is to compare Logs and AsteriskClient.php logic. It appears some values may not match or get lost due to Asterisk configuration or version. Not so importaint why - more importaint to make it working as it is.

Initial steps

1. Have Vtiger installed
2. Setup php.ini value for 30 seconds or similiar value (but not 600 seconds) - this will save your time waiting for logs to appear on screen and enable you to make changes faster. Restart webserver to apply changes (if necessary).

Start catching:

Catching done mainly by analyzing logs. So in order to do it lets approach to logs.
1. See how event logs looks like when you make no calls.
2. See how events logs looks like when you make calls.
3. Understand how AsteriskClient.php analyze this log and make pop-ups (not) pop-up.

1. See how event logs looks like when you make no calls.

- Start AsteriskClient.php by putting in your web browser similiar address
like http://vt-test.xx/cron/modules/PBXManager/AsteriskClient.php
Browser will behave like it keep opening this address with empty screen but keep waiting till php-script AsteriskClient.php will be stopped by webserver (you remember we changed php.ini value max_execution_time to 30 seconds to make this happen faster).

- Make no calls
- See what events log looks like

This sceen must be something like this - this is how your log looks like when you make no calls:

Right state

Wrong state

It means either you have manager.conf (in Asterisk) either Vtiger PBXManager configured wrong here:

So we need to achieve Right state - as described above. Only when you have Right state - it worth to continue.

2. See how events logs looks like when you make calls.
Now, after php-script is stopped and you have Right state on screen, make it run again (can just click refresh in browser) and make call to your Asterisk number. You must hear the ring, wait few seconds and denie call (hungup). Now wait till php-script AsteriskClient.php in your browser will stop and show Calling log. This may look something like this:

In this time I was calling from SIP-client 3898276589 to 008220773653 (associated with 8220773653). This is only one call done. When you have dozens of calls this turns to real mess. Now If you saw such log - you can continue to analize.

3. Understand how AsteriskClient.php analyze this log and make pop-ups (not) pop-up.
Actually popup not appear but 1 main reason - AsteriskClient.php "loose" some data necessary to generate window. This happens due to some Asterisk call manager syntax differences (i assume) from version to version. So to make it working - you need to change AsteriskClient.php the way not to "loose" this data.

For the moment I assume you don't see popup. So now is time to have a look at AsteriskClient.php and try to understand why popup not appeared. This quite non linear and intuitive process of working with log and with php-code. Result you saw in previour article regarding Vtiger popup. Now just some tips:
- Assume AsteriskClient.php "sees" the same log as you see on the screen Calling log. It analyzes only this data - not more not less.
- try to understand logic of AsteriskClient.php and check where it loose some data by putting php-command "echo" with some text info or variables like this.

- have a look at Log and this part of code:

 Similiar values marked by similiar color. So main task to analyze whole login of AsteriskClient.php and compare it to your Log - may be some values have different names or may be you don't have them at all, but wothout them AsteriskClient.php not pass your request further to so wanted pop-up.

Basic Linux Commands

mkdir - make directories

Create the DIRECTORY(ies), if they do not already exist.
 Mandatory arguments to long options are mandatory for short options too.
 -m, mode=MODE  set permission mode (as in chmod), not rwxrwxrwx - umask
 -p, parents  no error if existing, make parent directories as needed
 -v, verbose  print a message for each created directory
 -help display this help and exit
 -version output version information and exit

cd - change directories
Use cd to change directories. Type cd followed by the name of a directory to access that directory.Keep in mind that you are always in a directory and can navigate to directories hierarchically above or below.

mv- change the name of a directory
Type mv followed by the current name of a directory and the new name of the directory.
 Ex: mv testdir newnamedir 
pwd - print working directory
will show you the full path to the directory you are currently in. This is very handy to use, especially when performing some of the other commands on this page

 rmdir - Remove an existing directory 
 rm -r
Removes directories and files within the directories recursively.

chown - change file owner and group

chown [OPTION] --reference=RFILE FILE
Change the owner and/or group of each FILE to OWNER and/or GROUP. With --reference, change the owner and group of each FILE to those of RFILE.

 -c, changes like verbose but report only when a change is made
 -dereference affect the referent of each symbolic link, rather than the symbolic link itself
 -h, no-dereference affect each symbolic link instead of any referenced file (useful only on systems that can         change the ownership of a symlink)
  change the owner and/or group of each file only if its current owner and/or group match those specified here.  Either  may  be  omitted,  in which case a match is not required for the omitted attribute.
-no-preserve-root do not treat `/' specially (the default)
-preserve-root fail to operate recursively on `/'
-f, -silent, -quiet  suppress most error messages
-reference=RFILE use RFILE's owner and group rather than the specifying OWNER:GROUP values
-R, -recursive operate on files and directories recursively
-v, -verbose output a diagnostic for every file processed
The  following options modify how a hierarchy is traversed when the -R option is also specified. If more than one is specified, only the final one  takes effect.
-H     if a command line argument is a symbolic link to a directory, traverse it
-L     traverse every symbolic link to a directory encountered
-P     do not traverse any symbolic links (default)

chmod - change file access permissions
chmod [-r] permissions filenames
 r  Change the permission on files that are in the subdirectories of the directory that you are currently in.        permission  Specifies the rights that are being granted. Below is the different rights that you can grant in an alpha  numeric format.filenames  File or directory that you are associating the rights with Permissions
u - User who owns the file.
g - Group that owns the file.
o - Other.
a - All.
r - Read the file.
w - Write or edit the file.
x - Execute or run the file as a program.
Numeric Permissions:
CHMOD can also to attributed by using Numeric Permissions:
400 read by owner
040 read by group
004 read by anybody (other)
200 write by owner
020 write by group
002 write by anybody
100 execute by owner
010 execute by group
001 execute by anybody

ls - Short listing of directory contents
-a        list hidden files
-d        list the name of the current directory
-F        show directories with a trailing '/'
            executable files with a trailing '*'
-g        show group ownership of file in long listing
-i        print the inode number of each file
-l        long listing giving details about files  and directories
-R        list all subdirectories encountered
-t        sort by time modified instead of name
cp - Copy files 
cp  myfile yourfile
Copy the files "myfile" to the file "yourfile" in the current working directory. This command will create the file "yourfile" if it doesn't exist. It will normally overwrite it without warning if it exists.

cp -i myfile yourfile
With the "-i" option, if the file "yourfile" exists, you will be prompted before it is overwritten.

cp -i /data/myfile
Copy the file "/data/myfile" to the current working directory and name it "myfile". Prompt before overwriting the  file.

cp -dpr srcdir destdir
Copy all files from the directory "srcdir" to the directory "destdir" preserving links (-poption), file attributes (-p option), and copy recursively (-r option). With these options, a directory and all it contents can be copied to another dir

ln - Creates a symbolic link to a file.

ln -s test symlink
Creates a symbolic link named symlink that points to the file test Typing "ls -i test symlink" will show the two files are different with different inodes. Typing "ls -l test symlink" will show that symlink points to the file test.
locate - A fast database driven file locator.

slocate -u
This command builds the slocate database. It will take several minutes to complete this command.This command must be used before searching for files, however cron runs this command periodically  on most systems.locate whereis Lists all files whose names contain the string "whereis". directory.
more - Allows file contents or piped output to be sent to the screen one page at a time

less - Opposite of the more command

cat - Sends file contents to standard output. This is a way to list the contents of short files to the screen. It works well with piping.

whereis - Report all known instances of a command

wc - Print byte, word, and line counts
bg jobs Places the current job (or, by using the alternative form, the specified jobs) in the background, suspending its execution so that a new user prompt appears immediately. Use the jobs command to discover the identities of background jobs.

cat files - Prints the contents of the specified files.
clear - Clears the terminal screen.
cmp file1 file2 - Compares two files, reporting all discrepancies. Similar to the diff command, though the output format differs.

Network Topology

Computer network topologies can be categorized in the following categories.
• bus
• star
• ring
• mesh
• Tree.
Hybrid networks are the complex networks, which can be built of two or more above mentioned topologies

Bus Topology
Bus topology uses a common backbone to connect all the network devices in a network in a linear shape. A single cable functions as the shared communication medium for all the devices attached with this cable with an interface connector. The device, which wants to communicate send the broadcast message to all the devices attached with the shared cable but only the intended recipient actually accepts and process that message.
Ethernet bus topologies are easy to install and don’t require much cabling and only a main shared cable is used for network communication. 10Base-2 and 10BaseT are two popular types of the Ethernet cables used in the Bus topology. Also, Bus network works with very limited devices. Performance issues are likely to occur in the Bus topology if more than 12-15 computers are added in a Bus Network. Additionally, if the Backbone cable fails then all network becomes useless and no communication fails among all the computers. Unlike in the Star topology in which if one computer is detached from a network then there is not effect on the other computers in a network.

Ring Topology
In ring Network, every computer or devices has two adjacent neighbors for communication. In a ring network, all the communication messages travel in the same directory whether clockwise or anti clockwise. Any damage of the cable of any cable or device can result in the breakdown of the whole network. Ring topology now has become almost obsolete.
FDDI, SONET or Token Ring Technology can be used to implement Ring Technology. Ring topologies can be found in office, school or small buildings.

Star Topology
In the computer networking world the most commonly used topology in LAN is the star topology. Star topologies can be implemented in home, offices or even in a building. All the computers in the star topologies are connected to central devices like hub, switch or router. The functionality of all these devices is different. I have covered the detail of each networking devices in the separate portion of my website. Computers in a network are usually connected with the hub, switch or router with the Unshielded Twisted Pair (UTP) or Shielded Twisted Pair Cables.
As compared to the bus topology, a star network requires more devices & cables to complete a network. The failure of each node or cable in a star network, won’t take down the entire network
as compared to the Bus topology.
However if the central connecting devices such as hub, switch or router fails due to any reason,then ultimately all the network can come down or collapse.

Tree Topology
Tree topologies are comprised of the multiple star topologies on a bus. Tree topologies integrate multiple star topologies together onto a bus. Only the hub devices can connect directly with the tree bus and each Hub functions as a root of a tree of the network devices. This bus/star/hybrid combination supports future expandability of the computer networks, much better than a bus or star.

Mesh Topology
Mesh topology work on the concept of routes. In Mesh topology, message sent to the destination can take any possible shortest, easiest route to reach its destination. In the previous topologies star and bus, messages are usually broadcasted to every computer, especially in bus topology. Similarly in the Ring topology message can travel in only one direction i.e clockwise or anticlockwise. Internet employs the Mesh topology and the message finds its route for its destination. Router works in find the routes for the messages and in reaching them to their destinations.The topology in which every devices connects to every other device is called a full Mesh topology unlike in the partial mesh in which every device is indirectly connected to the other devices.

Topologies are the important part of the network design theory. A better network can be built if you have the knowledge of these topologies and if you know the difference between each topology. Similarly you should have the knowledge of each network device so that you can properly use them according to your network needs. A misconfiguration network can result in a waste of time and energy as well as a lots of troubleshooting methods to resolve the issue. So the basic understanding of the network topologies and network devices is a must to build a good network.

How to Hide a shared folder in Windows XP

If you want to hide a shared folder from the network users, right click the folder and click sharing and security and give a shared name of a folder plus $ sign e.g. e books$. In this way network users will not be able to see the shared folder on the network. For you to see the hidden shared folder, map the drive and type in the path including the $ sign in the folder box.
