[asterisk-users] Hello again

[aaberga/gmail]

Hi,

after a long pause (Asterisk 1.8 times), I have started again playing with VOIP. A lot has changed since last time I did setup an Asterisk system!

So I am asking for some help.

++++++++++++++++

PJSIP seems tougher..

So my problem is that I do have a test system up in the cloud, behind a firewall. I am trying to make the “Hello World!” mandatory call between two iPhones (with the Bria SIP client).

Outcomes are erratic.

This is the pjsip.conf file:

================================

This is a trace of what I do see from the console.

First I let the Bria clients connect. Then I try to call terminal 1 from terminal 2. Most of the times there is no route to the destination, even if it appears as an online AOR (whatever that means!! Ahhh: Good olde times of Peer, Friend, etc… ;-)

A couple of times I got a connection, with the typical one side only audio of NAT traversal problems.

BTW: The iPhones are behind TWO nats (one is given by the broadband router, one by the WiFi router that gives a better WiFi cover for in-house things).

My understanding is that I did something wrong in letting the phones ‘register’ them as present and available to receive calls. 

If only I knew what is wrong… I have tried random combinations of rtp_symmetric, force_rport, and friends; nothing final discovered...

Thanks in advance for any help,
Aldo


PS: Setting up Zoiper as IAX client works of course like a charm on the VOIP side. The only catch is that Zoiper has less than optimal background support on IOS… And I have no plan to make an IAX client myself!

I want to get my old Asterisk apps back online and the VOIP client part makes no sense to me..
