I noticed a change in IOS Gateways in how it deals with anonymous calls. Anonymous calls in version 12.4(25g) generates an SIP INVITE:
From: "anonymous" <sip:firstname.lastname@example.org>
A anonymous calls on version 15.1(4)M8 generates a SIP INVITE:
From: "anonymous" <sip:email@example.com>
The p-asserted-identity and remote-party-id did not change. None of our other SIP systems use the "anonymous@" format.
How do I get the 15.1 GW to use "<number>@" instead of "anonymous@" for these calls?
The only possible solution that i could think of for this scenario is through the use of SIP profiles on the gateway. There are quite a few posts and docs which you can check to try and configure one for your setup
The SIP profile will not work since the phone number is not in the from header and I cannot pull variables from different rules. Otherwise I would pull the RPI value and place it in the from header.
Do you know why this was changed in IOS without a mechanism to revert back?
