Hi,
I have configured a E1 PRI at Germany (CustomerA).
CustomerA is complaining that his clients are reporting that when they dial CustomerA they get busy tone 1st time and then when they redial the call goes through and its intermetent and not always.
It happens mostly when the clients are dialing from PBX.
Anyone faced this? thanks in advance.

Hi Atul,
I would 'debug isdn q931' and see who is originating the disconnect. If it is the gateway you may have codec or resource problems, if it's the provider you would need to contact them.

Hi Nick,
Thanks for your valuable comments, this router(2811) have PVDM2-32 and PVDM2-48, I am using only 10 sessions in dspfarm, so do you think there could be resource crunch? I will check the debug, if I have further queries I'll post it. If you have any more suggestions please let me know.
Regards

Hi Atul,
It's kind of an odd scenario - it sounds like there is a bug somewhere but you'll need to debug to find out where. You should be fine for DSP resources.
'show voice dsp group all' at the bottom will tell you if you are over-utilizing your DSPs.
hth,
