Cisco CME to Cisco UBE Options ping no-worky....
Did anyone get SIP options pings working on a pure Cisco router (UBE to UBE and UBE to CME) environment? I have a pure Cisco 15.1 network that we are playing with option pings on. I see pings go out and 200 OK responses, but dial-peers are still busying out. Have tried both default and example settings from Cisco UBE deployment guides. Routers are working with options pings from external ITSPs, so know options replies are working and are supported. So, what's the magic sauce on Cisco IOS 15.1 for SIP options-keepalive?

There are no firewalls or NAT between and when using "debug ccsip message" we see option sent and received and replies on both sides.

At least I don't feel that bad now - nearly 600 views with no solution. We validated this issue exist on 15.2 also.
