I don't quite follow you... what's on the wire in the sip packet, 481 or 491?
Do you have ngrep for the whole mess, including the 4xx responses?

Because I don't care what ya trunk to me with (Avaya, Nortel, Cisco,
Asterisk, etc), I tend to care less about the "end" user's equipment as
I'm sure many here have had to do from time to time. (Interops with
Avaya one day, Nortel the next, intertwined with CCM here, Asterisk there).
Anyhow, was doing an interop with someone and they CUCM was sending
491's. Figured I'd ask here since I believe someone must have a "oh
yea... that stupid thing..." response. The scenario: Caller (Cisco
Equipment) --> Their Network --> The Interweb --> My network --> so on...
Caller --> My phone --> I pick up --> Their phone disconnects, immediate
CANCEL 491
SIP? Caller --> CCM --> Router --> My SBC --> SIP/200 OK
At that EXACT MOMENT of the SIP/200 OK:
CCM sees SIP/481 :

Anyone have a generic Cisco router config they'd care to share? I was
fortunate enough to have them send me their end (implemented VoIP
