Regarding SIP Call

Hi Lei,

 

I am also facing  issue with sip registration . let me explain in brief i am using kamailio 4.4 

1 ) i created one user in kamailio and register in MCU (It was registering successfully and showing in kamailio online users list .

2) when i make call SIP call to MCU it was working good 

3) when my sip call disconnected unexpectedly due to connection loss or end point hangup the video in the MCU remains same when i end the call in the MCU and join again also it was remaining same untill i restart MCU 

4 ) when i restart MCU the sip call in the same MCU room room not working with same sip ID which i used before . But in kamailio active users list it was showing active 

5 ) In this case again i need to create new sip account in kamailio and need to configure to my MCU room then it was working 

 

please solve this issue or keep register and unregister buttons for sip configuration or please provide us the API nuve for sip which helps lot

Let me share what happened on our side with Kamailio 4.4.1, which allow simple user double registration, and each one has timeout interval setting around 1 hour. How about your side?

Kamailio registered users records:   (cmd> kamailio ul show)

  • First time MCU registered:

Domain:: location table=1024 records=1 max_slot=1

  • Restart the MCU:

Even though MCU would use the same SIP user name each time it registers, the branch id with bold text above is randomly generated,
