Hi,

 

 

We develop a recording server in our company. We have CUCM as the base for our VoIP infrastructure and another server where we will make the recording.

We have configured Call Recording profile on the CUCM to redirect calls to the recording server. We made some test and collected SIP messages . We try to get information from SIP messages but  can’t find correct Caller party Number and Called party number.

Here are two scenarios :

 

  1. 1.CallerPartyNumber is 2920, CalledPartyNumber is 9075521956

 

SIP->Message Header->From: "Antonie Zafirov" <sip:2920@10.0.0.8;x-nearend;x-refci=53701918;x-nearenddevice=CSFANTONIEZ;x-farendrefci=53701919;x-farenddevice=10.11.11.6;x-farendaddr=9075521956>;tag=1956042~b427bb50-23c0-4412-a63b-b141ffc498d3-53701923

 

  1. CallerPartyNumber is 9075521956, CalledPartyNumber is 2920

 

SIP->Message Header->From: "Antonie Zafirov" <sip:2920@10.0.0.9;x-farend;x-refci=20169130;x-nearenddevice=CSFANTONIEZ;x-farendrefci=20169127;x-farenddevice=10.11.11.253;x-farendaddr=9075521956>;tag=1229629~b427bb50-23c0-4412-a63b-b141ffc498d3-20169138

 

This traces are taken form the recording server

In both cases field To is:

SIP->Message Header->To: sip:2776@10.0.10.253

Where 10.0.10.253 is address of recording server and 2776 is Route Pattern to the recording server

 

Problem is that we don’t have information how to get who initiate the call and who receives the call.

 

We need a suggestion how to get that information?

Which protocol/interface/api to use about that?

Maybe some example who will help us?
