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*

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

[Sip-implementors] presence state and/or blf

2017-11-29 Thread Rolando Sanchez Espada
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.
Milton.
