Hi,
We have a remote site with a 2811 running 12.4(13r)T
There are 4 BRI ports and 2 FXS ports.
I have a fax connected to fxs 0/1/0
The dial-peers are configured like this :
dial-peer voice 7575 pots
destination-pattern 7575
port 0/1/0
The voice-port has the default configuration :
voice-port 0/1/0
!
voice-port 0/1/1
!
I can see when calling the fax number from a mobile phone that the BRI port becomes active
and the fxs goes to ringing :
CHSOSANyonISR#show voice port summary
IN OUT
PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC
============== == ============ ===== ==== ======== ======== ==
0/1/0 -- fxs-ls up up on-hook ringing y
0/1/1 -- fxs-ls up dorm on-hook idle y
0/2/0 1 bri-voice up dorm none none y
0/2/0 2 bri-voice up dorm none none y
0/2/1 1 bri-voice up dorm none none y
0/2/1 2 bri-voice up dorm none none y
0/3/0 1 bri-voice up dorm none none y
0/3/0 2 bri-voice up dorm none none y
0/3/1 1 bri-voice up up none none y
0/3/1 2 bri-voice up dorm none none y
50/0/1 1 efxs up up on-hook idle y
50/0/2 1 efxs up up on-hook idle y
50/0/3 1 efxs up up on-hook idle y
50/0/4 1 efxs up up on-hook idle y
50/0/5 1 efxs up up on-hook idle y
50/0/6 1 efxs up up on-hook idle y
However, I get a busy tone directly after this.
Any help will be much appreciated.
Rgds,
Jeroen

Hi, you need to take a trace with "debug isdn q931" and "term mon" to debug this.

Hi,
Thanks for your reply. I noticed that when I call the number, I first get a second dal tone for about 10 seconds and then I get the busy tone. This is the output of the debug :

I presume the port does not know what to do with the call.
Thanks for your help,

Hi, destination-pattern should be 75 as this is the number you're receiving.
Also check that you have configured;
network-clock-participate wic 2
network-clock-select 1 bri 0/2/0
network-clock-select 2 bri 0/2/1
If still problems collect "debug vpm signal" together with "isdn q931".

Hi, the translation cannot be checked from the debug you sent. Anyway, you still need to network-clock commands.
It is known that sometime calls remain hanging (never fixed bugs). The only solution is to reload router as they are non-cleanable.

For this trace the disconnection came from remote party. Was it taken with the network-clock commands in place? And yes you need them exactly as I've referenced above.
