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!
