RE: [Asterisk-Users] Problems with zaptel and TE210P

Did your Telco tell you what switch they are using?

Also change your timing settings in the /etc/zaptel.conf file to have this PRI do primary timing.

Thank you for the reply Alexandar.

After I restarted my dev machine I recieved these messages from asterisk:

chan_zap.c:2290 pri_find_dchan: No D-channels available! Using Primary channel 24 as D-channel anyway!

chan_zap.c:8202 pri_dchannel: PRI got event: No more alarm (5) on Primary D-channel of span 1

May 1 10:23:27 WARNING[3882]: chan_zap.c:2290 pri_find_dchan: No D-channels available! Using Primary channel 24 as D-channel anyway!

So you are right on the D-Chan. If my telco says everything is ok, what should I look at next?

AFAIK this PRI was in working condition before I moved it to the asterisk test machine.

Thanks!

Looks like your D-channel is down.

Ztcfg reports all is ok, b/c as far as iut is concerned, it is talking to your card just fine. LibPri handles the PRI implemetaton.

Since you are able to see the pri commands from the CLI, Isdn supprt is linked into your asterisk core.

Call your telco and ask if they have your D-channel in a loop.

Hello,

I'm just starting out with asterisk and I'm playing around with the system. Currently I have a Digium TE210P connected to a PRI on the Asterisk server. I have a SIP soft phone on my laptop for testing that is working fine. When I try to place a call from my soft phone I get this from Asterisk:

May 1 09:11:41 NOTICE[20098]: app_dial.c:1029 dial_exec_full: Unable to create channel of type 'Zap' (cause 34 - Circuit/channel congestion)

== Everyone is busy/congested at this time (1:0/1/0)

== Auto fallthrough, channel 'SIP/test-3a26' status is 'CONGESTION'

#/etc/zaptel.conf:

span=1,0,0,esf,b8zs

bchan=1-23

dchan=24

#/etc/asterisk/zapata.conf:

[channels]

switchtype=national

context=default

signalling=pri_cpe

group=1

channel => 1-23

#/etc/asterisk/extensions.conf:

exten => 123,1,Answer()

exten => 123,2,Playback(hello-world)

exten => 123,3,Hangup()

exten => _9NXXXXXX,1,Dial(Zap/g1)

Any ideas? Thank you in advance, your help is greatly appreciated.
