Sirish,<br><br>Since you're using an E1 to connect to the PBX then really all you need to do is keep track of the last time each port was hung up and whether or not a given port is currently in use. I would use api_on_answer to launch a simple script to set a flag to say that a particular port is in use and then use the api_hangup_hook to launch another script when the call ends.<br>
<br>The channel variables page on the wiki has some examples of how to use these. I recommend that you write simple Lua scripts that use the "hash" API to store information in the local database. Also, check out the "hash_dump" API as it is a useful way to quickly see what all is stored there.<br>
<br>For an example of how to add, remove, and read information from the local database using the "hash" API please see conf/dialplan/default.xml. Search for "hash" and you'll see all sorts of examples of how the example dialplan uses the local database to store useful information that allows us to implement features like call return, call intercept, etc.<br>
