We are having a problem with call forwarding from CUCM to the PSTN. Carrier is saying that the problem is we're sending Max-Forward of 6 and the hop count is being exceeded. The SIP profile on our SBC does not define a Max-Forward so it should be sending Max-Forward of 70. I've done a capture and do see that we are sending Max-Forward of 6 on the SIP invite. I've tried adding line "request INVITE sip-header Max-Forwards modify "Max-Forwards:(.*)" "Max-Forwards: 70" to the SIP profile. The call forward does come in on the remote device but the call cannot be answered. When I do a capture I can see we are sending Max-Forward of 701 on the forwarded call instead of 70. Looking for any guidance on how we might be able to resolve this. SBC version is Cisco 4331 16.6.5 and CUCM is 11.5.
