 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

Well, I thought I had the problem solved.  Ported everything over to 
PJSip and build RDNS records for the phones and the server, but I am 
still experiencing the problem on incoming calls.

I've faced the same issue. The issue was related to DNS, the reverse lookup
query failure caused the delay around(7-9 seconds). The purpose of reverse
lookup is to block IP Spoofing attacks.

I've seen this sort of thing where a DNS server is programmed in 
resolv.conf but is not accessible over the network. Threads get blocked, 
and you have to wait for the DNS query to timeout.
