Hi, I am using two Cisco devices (C3845 with Version 15.1(2)T2 and C3945E with Version 15.2(4)M6) to handle SIP calls. Calls works fine, but I have a problem with properly handling PAI or PPI Header in Incoming and Outgoing SIP Calls.
In Cisco documentation I found: "PAI or PPI Header Overview For incoming SIP requests or response messages, when the PAI or PPI privacy header is set, the SIP gateway builds the PAI or PPI header into the common SIP stack, thereby providing support to handle the call data present in the PAI or PPI header. To process the data from the PAI or PPI header of incoming SIP calls, we recommend that you enable the asserted ID for the incoming dial peer. For outgoing SIP requests or response messages, when the PAI or PPI privacy header is set, privacy information is sent using the PAI or PPI header. Note If the PAI or PPI asserted ID is not enabled either in dial-peer configuration mode or at the global level, the call data present in the PAI or PPI header of incoming SIP calls is ignored." So it looks that I can set (on Global Level or Dial-peer) only one of PAI or PPI privacy header support. I would ask you how to achieve support for both headers PAI and PPI Right now my customers can sends PAI and PPI headers but I cisco may properly handling only one of them. I would really appreciate for any help and advice how to configure cisco to support both PPI and PAI headers. Please help. -- Best Regards, Piotr
