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.

[Sip-implementors] Different TO Tag in SIP Bye as compare to SIP 200 OK
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* Any senior please advise if my understanding is correct and if can share any draft/document etc. Thank you in advance.

[Sip-implementors] presence state and/or blf
Hello, I am investigating about the service "state of presence", where a phone(like polycom) can monitor the state of the a group of phone and interact with them, however I can not find a straightforward way to achieve that with kamailio? I found several docs with several ways to implement it and looks like with old kamailio version, wondering if you can provide some sort of current docs and some aproach to best achieve that, no sure if it is accomplished with "SIP SIMPLE Presence Made Simple" or SIP/XML, I would appreciate you assistance. regards.
