I am having an issue with a couple of phones where they ring, but there is a long delay after the phone is picked up before the audio starts.

My setup:

 * Server running Asterisk 13.9.1, Dahdi 2.11.1 w/ OSLEC
 * Server is CentOS 7
 * Quad core CPU with 16GB Ram
 * 2 Snom 300 phones.
 * NO NAT.  Server and phone are on the same subnet with only a gigabit
   switch between them.
 * Digium TDM400 analog card with 2 incoming analog PSTN lines

When a call comes in, the system answers, IVR plays, caller dials an extension, Snom 300 rings, handset picked up. Caller continues to hear ringing for another 7 to 10 seconds. Answerer hears a click, a quick burst of audio, then silence, then another click and audio is engaged.

I have tried both SIP and RTP debugging and there are absolutely no messages indicating any timeout or retransmit. I am at a total loss. In the past I've always been able to find an answer to issues like this on my own, but this time I just don't know. I was even beginning to suspect the network switch might be bad, but pinging between the server and the phones shows no packet loss and 0.969ms average response time.

What am I missing*?*

Thanks,
Brent Davidson*
