User Disconnects Call

Recommended Posts

Hi there,

 

We are having intermittent issues where we drop calls. Sometimes after a dropped call I get an email saying User disconnects call in the subject. Email below. Also it seems that we cannot get past the 11 minute mark while on the phone. The call gets disconnected and the phone has to be rebooted in order to make more calls.

 

 

One side of the call between sip:15097207844@localhost;user=phone and sip:402@localhost did not receive media for 15.6 s and the other side of the call disconnected the call. The address of the other side was 66.23.129.253 (User-Agent=ENSR3.0.66.0-IS1-RMRG40340-RG2190-CPO3036). You may use this email as hint for a potential problem. The SIP messages are attached.

We are having intermittent issues where we drop calls. Sometimes after a dropped call I get an email saying User disconnects call in the subject. Email below. Also it seems that we cannot get past the 11 minute mark while on the phone. The call gets disconnected and the phone has to be rebooted in order to make more calls.

 

That is obviously a problem of the phone. The 7xx series had a couple of software images over the past few months. Not sure which is the latest one, but you need a new image.

 

One side of the call between sip:15097207844@localhost;user=phone and sip:402@localhost did not receive media for 15.6 s and the other side of the call disconnected the call. The address of the other side was 66.23.129.253 (User-Agent=ENSR3.0.66.0-IS1-RMRG40340-RG2190-CPO3036). You may use this email as hint for a potential problem. The SIP messages are attached.

 

That is a sign that there is trouble with one-way audio on hte trunk side. When the user disconnects the call, the PBX checks if the phone had to chance to hear anything, and in this case that seems not to be the case. It seems that your service provider does support the PBX running on a unroutable IP address, otherwise you would never get the INVITE from the SP. At first glance, it seems there is trouble with the firewall. Is this a cable modem router?

Not sure what you mean by software images? Are we talking about firmware?

 

We have a T1 line running clean into PBX with no firewalls. Any ideas?

 

Thanks,

Looking at the log, the call was established only for 21 seconds.

 

PBX sends 200 OK to the phone (760)

2012/2/27 14:50:42 Tx: tcp:192.168.1.10:53201 (860 bytes)
SIP/2.0 200 Ok

 

 

The user at 760 disconnects the call after not getting any media for 15.6 s.

2012/2/27 14:51:03 Rx: tcp:192.168.1.10:53201 (597 bytes)
BYE sip:402@192.168.1.26:5060;transport=tcp SIP/2.0

 

The issue could be anywhere all the way from the remote device/remote network/local network/Gateway/PBX/Phone etc

 

Just curious, is the remote side MagicJack?

Nope, the remote side is NexVortex in US

 

Any suggestions to help with my problem?

I would make sure that internal calls work fine. Make a couple of calls from the 760 to another phone and check if they are okay. If thats the case the problem is related to the SIP trunk. There we would have to focus on NAT related problems with the firewall, as they are most of the time the problem.
