[asterisk-users] Continued NTL ISDN issues with Vox D210E card

[Tim Guy]

Hi

Im getting no further will getting a Openvox D210E card connected to an
NTL/Virgin Media UK PRI connection.

Wondering if any of the following information might help?

If I try and dial I will get

"[May 22 19:58:13] WARNING[4087]: app_dial.c:1183 dial_exec_full: Unable
to create channel of type 'ZAP' (cause 0 - Unknown)"

I get various errors in the asterisk cli:

"  == Primary D-Channel on span 1 down
[May 22 19:51:32] WARNING[3749]: chan_zap.c:2402 pri_find_dchan: No
D-channels available!  Using Primary channel 16 as D-channel anyway!"

"  == Primary D-Channel on span 1 up"

Some reboots will give

"[May 22 20:29:49] ERROR[3884]: chan_zap.c:8248 zt_pri_error: !! Got a
UA, but i'm in state 7"

Pri Debugs:

"q921.c:777 q921_reset: q921_state now is Q921_LINK_CONNECTION_RELEASED
q921.c:728 q921_dchannel_up: q921_state now is
Q921_LINK_CONNECTION_ESTABLISHED"

"Sending Set Asynchronous Balanced Mode Extended" <repeated constantly>

"-- Got SABME from network peer.
Sending Unnumbered Acknowledgement"


I can 'sometimes' get the system to work on a reboot, maybe once in
15-20 times, then it fails again.

If I play around with the zaptel.conf and get it wrong so the zaptel
service doesn't start, re-edit, then start zaptel and then load asterisk
it works.

Currently running Asterisk 1.4.20 and Zap 1.4.10.1 on Suse 10.2 Ive had
to used the /etc/init/zaptel script fix to allow it to run on Suse
(http://users.otenet.gr/~becos/zaptel.init.txt)

Only thing I havent tried so far is dropping back to Asterisk 1.2 or an
earlier 1.4

Zaptel:
