[SIPForum-discussion] Q 1912.5 SIP to ISUP translation

[Calme, James A (Jim)]

Raghul,

Profile A was intended to align with interworking with an IMS network. The interworking closely aligned with 3GPP TS 29.163 at the time it was written (8 years ago).
Profile B is used for signaling toward a generic IETF based SIP network.
Profile C for SIP-I.

Profiles A and B differ because IMS (Profile B) had specific requirements, where it was left more open ended for Profile B.

Regards,
Jim

Subject: [SIPForum-discussion] Q 1912.5 SIP to ISUP translation

Hello All,

ITU Q 1912.5 talks about 3 SIP profiles A, B and C.

I understand Profile C is SIP - I, what is SIP profle A and B please?

I believe they talk about mapping of ISUP messages to SIP, if yes, why 2 profiles for the same purpose?


Thanks,
Raghul
