[OpenSIPS-Users] can several SIP phones with same SIP account ring together and hang up asynchronous

[chenyzzzz]

Hi Bogdan-Andrei,thanks for your reply. I had set up a opensips service on my Ubuntu 18.04.6 , and opensips version: opensips 3.2.6 (x86_64/linux). 
When I test that case,  I use two desktop linphone login same sip accout 01010101 (callee A/B).  and I use my Android linphone(caller C) invite A/B, A/B rings together which works well. but I hang up the callee  A ,  B also  terminated .  I use wireshark to capture the packet on server side.  it show that : 1. when callee A(192.168.2.123) hand up, it respond 603 to the server(192.168.2.108) 2. server(192.168.2.108) forwards the respond 603 to caller C(192.168.2.115) 3. server(192.168.2.108) create a CANCEL to callee B(192.168.2.127) so, it seems opensips server CANCEL B automatically. 
My project need to meet the ability that callee A declines but callee B still ring.  I am a newbia to opensips, I don't know what is going on .  How to enable the ability as you say?
Best Regards,


Chen
