Help Me! - Configuring Digum Wildcard E100P with Asterisk

Asterisk Asterisk Support
1

Hi,
I am very new to Asterisk and I have a task of configuring my Asterisk server with a E1 card.

When I dial the configured number I get the following error :

Unable to create channel of type ‘Zap’ (cause 34 - Circuit/channel congestion)

and then

Timeout, but no rule ‘t’ in context ‘sip-out’

I tried my best to search for a solution my reading hundreds of forums, articles and some Asterisk books. But no luck yet. So anyone please give me some hint, I would be so glad!

Here are my extension files (the relevant parts)

=============================================
zapata.conf :

[channels]
language=uk
context=isdn
switchtype=euroisdn
signalling=pri_cpe
dchan=16
usecallerid=yes
hidecallerid=no
pridialplan=local
usecallerid=yes
hidecallerid=no

callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
echocancel=yes
rxgain=0.0

txgain=0.0
group=1
channel=>1-10

===============================================
zaptel.conf

span = 1,1,0,ccs,hdb3,crc4
bchan=1-10
dchan=16
loadzone=uk
defaultzone=uk

===============================================
extensions.conf

[default]

[sip-in]
;exten => s,1,Answer()
;exten => s,2,Playback(hello-world)
;exten => s,3,Hangup()

;exten => 123,2,Hangup( )

[sip-out]

exten => 103,1,Dial(Zap/g1/3)
exten => 104,1,Dial(Zap/g1/4)
exten => 555,1,Dial(Zap/g1)

exten => 1234,1,Answer()
exten => 1234,2,Playback(hello-world)
exten => 1234,3,Hangup()

exten => 124,1,Answer()
exten => 124,2,Background(invalid)
exten => 124,3,Hangup()

[isdn]
exten => s,1,Answer()
exten => s,3,Hangup()

exten => 123,1,Dial(SIP/221)

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

Please go through this and give me a hint so that I can move on! I am stuck very badly. Don’t have much time to Start from the basics of Asterisk.

can you post the debug log?

first off, in zaptel.conf you should define all the channels on the PRI, not just the ones you’re using.

we could really do with a proper log output for a failed call.

you could try overlapdial=yes pridialplan=unknown prilocaldialplan=unknown in zapata.conf, replacing the pridialplan setting you have.

edit: if you don’t have much time, are you sure you want to be doing this ?

Hi,
I got this work suddenly, so I was not in touch of this area! I have no option than meeting the deadline! :astonished:)

Btw, thank you for the help.

I implemented all the channels

===============================================
new zapata.conf

[channels]
language=uk
context=isdn
switchtype=euroisdn
signalling=pri_cpe
dchan=16
usecallerid=yes
hidecallerid=no
usecallerid=yes
hidecallerid=no

overlapdial=yes
pridialplan=unknown
prilocaldialplan=unknown

callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
echocancel=yes
rxgain=0.0

txgain=0.0
group=1
channel=>1-15
channel=>17-31

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

new zaptel.conf

span = 1,1,0,ccs,hdb3,crc4
bchan=1-15,17-31
dchan=16
loadzone=uk
defaultzone=uk

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

But no progress! The same error message!

What alarms do you see in zttool?
What does the PTO say about the link.
Have you tested the link with a simulator?
what does zap show channels say?
what is in dmesg with relation to the card?

Im sure there are other questions, But thats enough for now :smile:

Ian,

No I haven’t checked the link with a simulator. Is this cause 34 an ISDN error? Is it the same error given because of a problem in the E1 link?

My setting was as follows:

|| Asterisk Server — E100P ||<==link==>|| NMS Board – VoIPserver||

But now I am in deep trouble,

The Asterisk server was removed from the network so that I have to install Asterisk in a new server and configure the E100P Digium card in the new machine!

Now I am starting at the very bottom of the ladder!!!

How do we install a E100P card and configure it properly?

Please be kind to give me a hint or a link where I can find the proper information of the way I do this configuration.

Thank you so much in advance!!!

The configuration for TE100P is similar to that for TE110P.
The documentation regarding configuration can be found at the digium site.

Finally solved the problem, which was in the link
Thank you very much for all the help given by all of you guys!
