Outboundproxy issues on FreePBX Distro 5.211.65 with Asterisk 11, FreePBX 2.11, DAHDI 2.8 and CentOS

General Help

I’ve been trying to track down why a sip trunk isn’t registering and am starting to wonder if the outbound proxy isn’t working? As far as the SIP debug logs show it doesn’t show any signs of using the outboundproxy setting…

Internet research shows some older posts saying that it might be an issue with Asterisk compatibility — I’m using v11 and haven’t tried any other versions.

The logs show a failed address info on strata8.net — but the provider tells me that shouldn’t be necessary as that is an internal domain and thus requires use of the outbound proxy…

Every other provider I’ve worked with has just needed the host entry… so unfamiliar with the outboundproxy setting

Well it’s not working and doesn’t exist as far as my view of the internet goes :slight_smile:

I also tried FreePBX Distro 5.211.65 with Asterisk 1.8.26.1, FreePBX 2.11, DAHDI 2.8 and CentOS same problems.

I am able to get this to work with a SIP client (Telephone on OS X w/ the proxy settings enabled) working both calling in/out.

From your first post

[2014-03-31 16:56:18] WARNING[3156] acl.c: Unable to lookup ‘strata8.net’

strata8.net does not exist on my internet, maybe it does on yours :slight_smile: perhaps you should use 773xxxxx:[email protected] to register until they resolve their dns issues.

7

The strata8.net is only accessible via the proxy which is my issue. Confirmed as working outside of Asterisk with SIP phone client via the proxy. My expectation is that the “outboundproxy” option should cause every type of SIP request to be sent to that address, which doesn’t appear to be working…

8

Yes, it is your issue as asterisk cannot resolve and hence connect to it, just like the log says, you need to fix your local name service before anything else or as i suggested use it’s ip address.

Okay so added

outboundproxy=208.90.249.3

to
/etc/asterisk/sip_general_custom.conf
and
/etc/asterisk/sip_custom.conf

Global Signalling Settings:

Outb. proxy: 208.90.249.3

now its registered for inbound

strata8.net:5060 N 773xxxxxxx 24 Registered Wed, 02 Apr 2014 00:16:03

Yay!!! Lots of hours later some progress…

Yet now I can’t make outbound calls…
= Unable to create channel of type ‘SIP’ (cause 20 - Subscriber absent)

and inbound requires the anonymous option since the requests are coming from the proxy IP rather the the host = Rejecting unknown SIP connection

Doh…
Why is it so painful to work with a new provider.
