Hello,<br>
<br>
There is no need to develop an extra module for this. <br>
You can use the exec_avp() function from the exec module ( see #1)
and call an external script ( bash, python, etc ) that runs your
logic, and returns the result back to OpenSIPS. Based on the
external script results, in the OpenSIPS script you can drop or
further relay the message.<br>

font-size: 10.5pt;"> Our project want to add some additional functions on the sip server. The primary is when the server received an invite message from a sip phone, amd the server should get the src-ip and the des-ip of the session. Then send the src-ip and the dst-ip to another computer, in which we run a application that have the informations about the resource of the network (By the way,the server and the sip phones are all in an LAN). Then the application will tell the server whether it should allow this session. In another word, we want to add a judgement in the sip session.</span><span
