Hello,
I'm experiencing some weird problems on my server:
- 1) The following messages are filling up my logs:
[Sep 29 08:24:59] WARNING[7077]: chan_dahdi.c:2789 pri_find_dchan: No

[Sep 29 08:24:59] WARNING[7074]: chan_dahdi.c:2789 pri_find_dchan: No
D-channels available! Using Primary channel 47 as D-channel anyway!
In the Asterisk CLI>, i'm watching these messages constantly
2) I've plugged in a real E1 PRI ISDN:
r...@sangoma-testing:/usr/src# asterisk -rx 'pri show spans'
PRI span 1/0: Provisioned, In Alarm, Down, Active
PRI span 2/0: Provisioned, In Alarm, Down, Active
PRI span 3/0: Provisioned, In Alarm, Down, Active
*PRI span 4/0: Provisioned, Up, Active*
PRI span 5/0: Provisioned, In Alarm, Down, Active
PRI span 6/0: Provisioned, In Alarm, Down, Active
PRI span 7/0: Provisioned, In Alarm, Down, Active
PRI span 8/0: Provisioned, In Alarm, Down, Active
Seems to be OK! but i can't make a call:

What is happening?
Could you let me know how to debug or to understand the output from "pri
intense debug span 4"?

What should i check on the above span debug? what's important there? the
timers? the ACK? SAPI? TEI? is there any place to learn how to understand
this output?
Hope you can help me
Verions of my server:
libpri version: 1.4.11.4
Asterisk 1.4.24.1
DAHDI Version: 2.4.0
WANPIPE Release: 3.5.15.4
Please don't ask me to upgrade my Asterisk Version, the idea is to test this
environment
Best Regards!
