[asterisk-users] Delay after Answer

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.
* 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*?*
