Hello,

are you using presence modules in kamailio to handle the SUBSCRIBE? Or you forward it to the other party and the NOTIFY should be end-to-end?

Can you capture with ngrep the SIP traffic on kamailio server for SUBSCRIBE and NOTIFY transactions? If yes, you can send it here and we can check if something is wrong with the routing headers.

Cheers,
Daniel

I used pjsip in client side to send NOTIFY when user change status (presence), another user already SUBSCRIBE to this user should receive NOTIFY message from kamailio but it did not. I still dont understand why comment out alias line effect to this issue. Any advise?

Thanks,

Nhan

Which party/application sends the NOTIFY?

The alias is typically the sip domain, so there should be some misconfiguration in another place.

I figured out that when I add alias=mydomain.com than kamailio did not send notify when uac send public message. I comment out alias line in cfg file than it works.

Thanks,

what do you mean by "SUBSCRIBE message does not work"? Is not received
by Kamailio? Or is not routed as expected? Try to describe in more
details what it happens and what you expect to happen in order to be
able to help.

Cheers,
Daniel
