All channels are busy!!

Hi Team,

I configured a H323 gateway and initially it was working fine a couple of hours back. We have 6 PRIs out of which 3 are one Service Provider (SP) and another 3 r a different SP. Now the out going calls are happening through all the pris. In one SP pri the incoming call is not happening, it gives an error message All the channels are busy. I debuged it and the cause value is 34. Have attached the gw conf.

Which SP is not working inbound?  RELIANCE or TATA?

Can you gather the following debugs when a call comes in and fails.

debug isdn q931

debug h225 asn1

Regards,

Jesse

Hi,

I have cornered this issue. The issue is with the number of digits which reliance are sending. Reliance sending eight digits and tata are sending five digits. So i have asked reliance to send five digits as required by our configuration. Hope it solves it. Thank you all.

You can also configure your system accordingly. That is usually easier than asking telcos change their side.

Note however than received digits has no effect whatsoever on outbound calls.
