Asterisk 11.9.0 PRI No Ring Indications

Hopefully someone can point me in the correct direction.

I had a 1.4x system die on me yesterday, while I was prepping a new machine to replace it. Took the machine on site yesterday and spent the day and part of the evening getting things working.

This morning, I finished up converting my dial plan, knowing there’d be calls of things that I missed.

While testing, I’ve noted that all inbound and outbound calls over the PRI give no ring indications. This is my second converted system and the first system doesn’t have this issue. The system is out of the Detroit, MI area and the provider is TDS.

One thing of note: I originally started off with 11.12.0, but was having problems with paging and the sound card, so I back dated to 11.9.0 (Same as my first convert) after I deleted the /var/lib/asterisk/modules folder.

Machine setup below:

lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 7.6 (wheezy)
Release: 7.6
Codename: wheezy

uname -a

Linux livasterisk 3.9.11-custom-3.9.11 #1 SMP Thu Jan 9 12:18:01 EST 2014 x86_64 GNU/Linux

Any suggestions would be appreciated!

  • Have you checked your /etc/asterisk/indications.conf file? I know I had a couple systems where I tried to be minimalist with the config files I used, and forgot to bring the indications.conf over from the samples — the symptom those times was that the caller (inbound, outbound, or extension to extension) wouldn’t hear any ringing tone while the call was ringing at the other end.

    At the CLI, you can use “indication show” to list all loaded indication types, and “indication show ” to see the details about a specific one. I can’t remember/find the way to display in CLI what the currently loaded default indication zone is, though there should be a line in the indications.conf file at a minimum.

    Thank you,

  • I copied the indications.conf file from the working system, it didn’t work. The size was different, I did a reload at the console, but don’t know if a restart of asterisk or dahdi needs to be done for it work be read.

    I’m also planning, after hours, to move back to 11.12.0 with a make config and start again. Maybe moving back to 11.9 wasn’t a good idea.

    Thanks for your input,

    Well that didn’t work.

    Even started with a fresh set of configuration files. A basic chan_dahdi.conf and a basic dahdi system.conf.

    Audio passes fine, I can even specify a default music on hold to play during the dial (Thinking of playing a ringing sound). I’m just not getting any ringing.

    Is it possible the card is bad?

  • Ringback problems are a pain in the neck to troubleshoot. You don’t mention your endpoint, but if the endpoint is sip, play around with the prematuremedia and progressinband options in sip.conf. The comments for these two settings in sip.conf.sample are completely and totally confuzing. Try different compications and see if any of them make any difference.

    Both ends of the PRI. In house the end points are SIP phones, but calling from a sip phone (Polycom) to our remote office, there is no ringing.

    I’ll be on site again this Saturday. I may end up putting the old 1.4x box back into place, I did get it working again.

    Setting my system.conf to uk instead of us gets me ringing on my RPI, although in a UK format.

    Sounds like a bug to me. I’ll review the issue tracker
