Oh sorry, I didn’t catch that on the receiving part. Well, I probably should re-look at some of the commands, but we were one of the first adopters of SIP and not all the defaults that exist today, existed back then. Some of it got left in cause it works with the carrier. :) Some of it was also trial and error with the carrier, and well when it starts working sometimes things don’t get revisited…. Hows that for an answer!!!

Maybe if you grab ccapi inout debugs at the same time, your voice service voip section (at least, whole config would be better), sh ver, and show run | sec voice. Maybe even do a debug ccsip all if you have the ability to do that and NOT crash your CUBE. Obviously don’t debug ccsip all without thinking about what that will do.

I’ve had similar issues with my CUBEs and it was due to binding issues and another time it was a straight up bug and I had to bounce the box (which “fixed” it). I don’t know why your initial debug was showing “could not add ccb to table” and I’m not even sure which CCB it’s talking about. My thoughts were that is customer callback… but I’m probably wrong on that one.

>> I feel obligated to reply, since I chimed in earlier....unfortunately, I don't have any ideas for you. In fact, I have seen CUBE just ignore incoming SIP messages before, both OPTIONS and INVITEs alike. Not many occasions, just a few. I have never gotten resolution on it, it has either fixed itself, or in one special case, still happens. It's my own, in fact. It still randomly ignores inbound INVITES from my ITSP. Fixing it, is on my to-do list, but... The cobbler's children are always the worst-shod <https://english.stackexchange.com/questions/46681/a-saying-indicating-how-some-professionals-dont-apply-their-skills-for-themselv>. The Calls Per Second on my CUBE is like 1.7, however, there are no other calls being setup, torn down, sup service, etc, and CUBE still just ignores its responsibility.

>> OPTIONS does not have to match a dial peer to work. However, if you are going to match a dial peer at all, it would likely be for the express purpose of replying from the correct interface, if you have more than one potential interfaces, and you for some reason cannot bind globally. Thus using the correct bind statement on a dial-peer for OPTIONS reply, would be necessary. In which case, you would need to match an incoming call leg dial peer by the SIP Via header alone, and not, say for example, incoming called number.
