PRI Callerid Passthrough


Hi All, I have to forward incoming call on PRI back out to PRI but I need the original Callerid to passthrough. Is it possible with DAHDI PRI cards without involving the service provider?

What Would Cause A Drop Between Two Asterisk Systems?


We have an asterisk frontend terminating all our SIP phones to, and an asterisk backend with a wildcard PRI card in it connecting to the PTSN. The frontend handles 99% of dialplan logic and just hands off anything outgoing to the backend via IAX2, which dials out on one of the open channels.

Lately we've been getting a disconnected calls. Keeping the consoles running it doesn't seem to be the PRI initiating the hangups, as I'll when I see hangups intiiated on the backend / PRI side:

-- Span 2: Channel 0/21 got hangup request, cause 16

Instead, I'm seeing

Congestion() Forcing PRI Channels To Be Not Available


Hi, I have a PSTN Asterisk box that's connected to other dialplan PBXes through IAX2.

Recently this box was upgraded to 1.4.44 with the latest DAHDI version. I've noticed that if one of the dialplan PBXes calls Congestion(), the PRI will return ISDN code 34 (as its supposed to do). However, the issue is that subsequent calls into that PRI channel are immediately responded by a Code 44 (channel not available) even though there is no live call on the channel.

Has anyone else experienced this behavior? Its a pretty crippling behavior since all of our channels eventually become unresponsive until a…

23B + D Asterisk TDMoE (packetized PRI) Link Question.


Can anyone help me find a specification for the 23B + D Asterisk TDMoE (packetized PRI) link?

I am having occasional packets arrive from the Asterisk Server that do not have the standard four leading characters in front of the MAC addresses, and am not sure what this implies. For now, I discard such packets.

Also, I'm getting HDLC abort messages from the Server that occur almost exclusively in heavy call set-up traffic, despite that the PRI-style messages in both directions appear to have correct indices, Call Reference Numbers, etc.

If you can answer the question or if you…

Audio Fades Out Over PRI


I am using asterisk 1.4.43. When I call over the PRI to a single phone and play my recorded message its heard just fine. When I call over the PRI to a single extension (the switch then takes 3 phones offhook in intercom mode) and play my same recorded message the audio is dropping out and the whole message is not heard.

What might this be? I think its the other switch - but if we use that switch to call that same extension and speak the audio does not drop out at all....

What can I look at?
