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 openser do not send the BYE request to 111111 . So
111111 stays connected. & the BYE request keeps looping infinitly in
openser.
