[SIPForum-discussion] IBCF to IBCF

[Sumeetkumar Bhardwaj]

Hello,

PAI header is suppose to contain some critical values of private network which must be removed from the SIP message when it goes from trusted network to untrusted network.
There are similar kind of headers like PAI which needs to be removed when it goes to untrusted network and are not part of SIP RFC 3261. They are suppose to  flow only in trusted networks (Like PANI and PAI etc).

I think, The headers which are present in SIP RFC 3261 can be carry forwarded to untrusted network. 

Thanks,
Sumeet

Folks,

I'm doing study for interworking between IMS-IMS using IBCF.. Another IMS is treated as Untrusted Network..
Which SIP header can be allowed to carried out from my network to another network? How about PAI header?

regards
Ridhuan
