The SIP signalling looks "beautiful" as far as I can see. My worry is that the phone obviously did not receive any (valid) packet. Why the phone thinks that 1 billion packets have been sent from remote is another question (I suspect a minor glitch in the phone).

 

Because the phone is in the same subnet like the PBX, I don't think we have the usual firewall/NAT problems. My feeling is that there is something wrong with the SRTP. Anything in the phone that hints after MAC check problems? If you can, try to use TCP transport layer for that phone; then the RTP should be unencrypted and we can rule out that SRTP is the problem.

Hi, I disabled SRTP but the problem is still present. The PBX is not in the same subnet as the phone.

 

Phone is in 10.246.0.0/24 while pbx is 10.252.0.0/24

 

they are connected through a MPLS network.

I don't understand why it does not work only sometimes.

Hmm. Seems to be tricky. Are IP address conflicts possible? Or are certain ports blocked somewhere down the routing path? MPLS sounds very good in principle; maybe you can double check if the routing from the PBX to the phone works like a no-brainer.

 

Update

 

I switched

Follow RTP off

 

and for the moment we haven't had any issue.

 

I did not say earlier that on the same subnet there is another SIP PBX. Maybe snomONE listened to the RTP sent from the other PBX and disconnected the RTP that he was supposed to stick with. Could this be the reason of the disconnection?
