asterisk users - Jan 2014 - Get data from the SDPof SIP INVITE message

B.H.

Hello, all

I'm using Asterisk 11.7, connected to PSTN using SIP trunk.

I'm looking for a way to get data from INVITE's SDP. Specifically, i
would
like to get a value of o= for incoming call from PSTN because it contains
data about the operator that the call originates from.

I have googled for a solution and found this patch:
https://issues.asterisk.org/jira/browse/ASTERISK-14510 which looks like
exactly what i need, but, unfortunately looks like it was abandoned or
forgotten.

The patch is against older version of chan_sip and i don't know how to
apply it against the current version. I'm not enough familiar with chan_sip
internals.

Is there any way to do this with the current version of Asterisk?

Thanks in advance!

I'm afraid not, the only information in the dialplan even remotely 
relating to SDP is the RTP address information.
