I just rebuilt my Raspberry Pi asterisk server with Raspbian Jessie, Asterisk 13.6 and bcg729 all built from source. It is very similar to the previous system I was running until last Sunday although for reasons I don’t want to revisit I don’t have all the settings I had then. I am using the same network (home network with router to DSL with static IP) as before when everything worked fine.
I have 3 SIP phones on the home network plus a SIP ATA and they all talk to each other fine through asterisk. I have a voip provider who supports IAX and asterisk registers with it and the provider’s web site acknowledges that I am registered.

1 IAX2 registrations.

When I try to place a call, however, it fails with max retries exceeded. I can see with tcpdump that messages (not many, just a send and a response, repeated several times) are passing back and forth on port 4569. I can’t even make a call to the digium pbx with the simplest possible path through my dial plan.
I’m getting that “stuck” feeling and hope that someone might have a clue about what’s going on. Here’s the dial to my voip provider
-- Executing [start@Dialer:1] NoOp("SIP/000BBE1CEBCC-00000003", "Placing Call") in new stack

[Oct 27 19:38:08] WARNING[4752]: chan_iax2.c:3571 __attempt_transmit: Max retries exceeded to host 184.75.215.114 on IAX2/voipms-26528 (type = 6, subclass = 1, ts=7, seqno=0)
Could it be something different between v11.something I was running before and v13.6?
If I call my number from the voip provider I see an incoming message but nothing on the asterisk console. Not even with IAX2 debug on.
Just in case you’re wondering, I have the firewall off. My router also maps port 4569 to my asterisk system.
