Good afternoon everyone.
I have a customer that runs a recording application that look at the SIP header to record calls. Here's the call flow:
CallManager 4.1(3) SIP Trunk => Recorder.
The recorder is expecting something like:
INVITE sip:[email protected] SIP/2.0
I've never really worked with SIP, I was wonder how it can be done.
Could someone point me to a document on how to do this.
Thanks in advance.
