Dear All,
I have the problem where the customer is sending the BYE after 200 OK, but
my switch refused to identify the dialog and sent the SIP 481, and I feel
this is because of different TO tag.
SIP 200 OK in the correspondence of initial Invite.
*Switch to UAC*
From: "" ;tag=6H3KeXvvcFDQg
To: ;tag=*gK09c21acd*
*UAC to Switch*
From: "" ;tag=6H3KeXvvcFDQg
To: ;tag=*v5kVTeFILvVHE8nhSC71RxPENPrbcwAq*
Please say more what you mean by "switch", and provide more detail:
preferably all the messages from the INVITE to the BYE.
Trying to guess from what you have above, I infer that the client (UAC)
is +122, and is calling 0 that is handled by the
"switch" (UAS). And the message containing the first From/To is from the
200 OK to an INVITE from the client, and then the 2nd From/To is from a
BYE sent by the client.
If so, and nothing else funny is going on then I agree that the client
is messing up by including the wrong to-tag.
Thanks,
Paul
