Questions about B100/200/400/800 ISDN BRI Cards
b800p, Sporadically Dial out fail
14 years 9 months ago #3515
by slutec18
have a trixbox installation with a b800p with 6 ISDN lines configured in PTP mode.
Versions are Trixbox 2.6.2, mISDN 1.1.7, asterisk 1.4.25.
B800P board is configured with
in mISDN script i have the following settings
HFCMULTI_protocol[${i}]="0x22,0x22,0x22,0x22,0x22,0x22,0x22,0x22"
HFCMULTI_layermask[${i}]="0xf,0xf,0xf,0xf,0xf,0xf,0xf,0xf"
the mISDN.conf in /etc
<mISDNconf>
<module poll="128" debug="0" timer="no">hfcmulti</module>
<module debug="0" options="0">mISDN_dsp</module>
<devnode user="root" group="root" mode="644">mISDN</devnode>
<card type="BN8S0">
<port mode="te" link="ptp">1</port>
<port mode="te" link="ptp">2</port>
<port mode="te" link="ptp">3</port>

The system works well but I have the following problem. Sometimes, usually twice a week the system gives me a dial out failure.
In that circumsance I can receive calls as before but I cannot perform outbound calls.
The only solution is to reach the ssh console in the system and givean "mISDN restart", after that the system returns to normal operation and i can perform outbound calls outbound calls again. I heard the some telcos power off their ISDN to save the power but the strange think is that I get a dial out failure when all the employees are working and not during the night or sundays when everybody is sleeping. Also in misdn.conf I have pmp_l1_check=no and the ports are not configured in group (ports=1,2,3,4,5,6,7,
, so in asterisk the outbound call is performed by choosing directly the channel in sequential mode (from the first to the sixth) and not by calling using a group of trunks.
I tried to search in the forums without success. Someone is telling that is related to telco interrupts in the line.
What can I do with this issue. Is there a way for debugging and try to reproduce this issue?
Your help is really appreciated.
