Iâ€™m having a lot of problems with getting my four analog lines to work.
First Iâ€™ll give you a overview of my hard- en software used :
Server : HP Proliant ML110 G5 (Intel Xeon with 6 GB internal memory, 2x 250 GB HDD (RAID1))
Telephonycard : Sangoma A200d with 2 FXO modules inserted (so, four analog lines with Hardware-EC)
4 external lines ; 3 lines from one provider (KPN Netherlands), bundled as one number and 1 line from another provider (Versatel Netherlands), mainly used for incoming faxes.
Operating System : CentOS 5 (2.6.18-128.1.1.el5xen), XEN kernel.
WanPipe version : 3.4.4
Dahdi version : 220.127.116.11
Dahdi-Tools version : 2.2.0
Asterisk version : 18.104.22.168
The problem :
Every time I restart the server, or just asterisk and wanrouter, it is the question which lines are working.
To explain it simply Iâ€™ve three states in which a line can be :
- When calling to the asterisk server (for example with my mobile phone), the server picks up the call, but no sound is heard.
- When calling to the asterisk server (for example with my mobile phone), the server picks up the call, sound is heard, but DTMF is not working (Iâ€™m using a IVR menu).
- Line is working perfect; the server picks up the call, sound is heard and DTMF is working. People get to an extension and can have a conversation.
So when I restart the server, sometimes line 1 is in state 2, lines 2 and 3 are in state 3 and line 4 is in state 1.
When I change NOTHING in the configuration and restart the server, line 1 and line 3 are in state 3, line 2 and 4 are in state 1.
These are just examples, every line can be in another state after a reboot. Sometimes all lines are in state 1 (nothing is working), and a very rarely time all lines are in state 3 (everything is working).
At this time of writing Iâ€™m running on 3 lines (lines 2, 3 and 4 are in state 3), line 1 is in state 2. Because itâ€™s a live system (people are depending on it), Iâ€™m afraid to reboot it again, because it can take one to twenty reboots before everything is working ok.
And again: I donâ€™t change a single file on the server before I reboot the server.
Iâ€™m experience this behavior since the first installation of the server back in April 2009. Iâ€™ve updated all relevant software (wanpipe, dahdi and asterisk) several times and completely reinstalled the server on a Sunday back in June 2009 (not my favorite waste of time on a Sunday).
I hope someone can give me a clue, because the only thing my boss does give me is a …
