[OpenSER-Users] Need help to solve BYE signalling problem

[Krunal Patel]

Hi,

++ I have registered 3 UACs to the same openser server which are behind NAT.
     UAC 1 -- 111111
     UAC 2 -- 222222
     UAC 3 -- 333333

++ So in location table , I am getting :


------------------------------------------------+-----------------------+--------------------------
                         Contact                                |
Received          |

------------------------------------------------+-----------------------+--------------------------
         111111@<private-IP>:5060                |  sip:public-IP : 5060|
         222222@<private-IP>:5060                |  sip:public-IP : 5060|
         333333@<private-IP>:5060                |  sip:public-IP : 5060|

++ I have set user preferences :


+------+------------------+-------------------------+-------------+------+------------------------------------------------------+
| uuid | username        | domain                       | attribute   | type
| value                                                               |
+------+------------------+-------------------------+-------------+------+------------------------------------------------------+
|         | 222222              | domainname.com     | fwdbusy     |    0 |
fwdbusy:sip:333333 at domainname.com <fwdbusy%3Asip%3A333333 at domainname.com>
|         | 222222              | domainname.com     | noanscfwd |    0 |
noanscfwd:sip:333333 at domainname.com<noanscfwd%3Asip%3A333333 at domainname.com>
+------+------------------+-------------------------+--------------+------+------------------------------------------------------+

++ I am using mediaproxy for audio signaling.

++ Now I am dialing 222222 using 111111 & keeps 222222 ringing until it
stops automatically. So call is being forwarded to 333333.

     111111 ---------------> 222222---------------> 333333

++ I pick up the call . So 111111 & 333333 is connected.

++ Now I hangup 333333 , so it sends BYE request to 111111.

+ Now the problem is 111111 do not accept the BYE request. So it stays
connected. & the BYE request keeps looping infinitly in openser.

Here is the BYE request :

++ From the parsing of BYE request , I found evenif I am doing loose route
in cfg , It is doing strict route.

Can you please help me to solve this.

Thanks in advance.
