Hi,

Can anyone tell me what this error message indicate?

**ERROR**: call_progress: DEV_CONNECTED VOICE ERROR: Bearer capability not available(0x3A): b channel 17 call id 0x274C

I've counter a problem with my VOIP where users can't hear the voice clearly, then I use the 'debug q931' command at the router connected to PABX thru PRI. The error above popup along with other normal message. Can anyone help me?

Thanks.

I have this problem too.

Hi Azmir,

this error message is normal. I have it on all the ISDN installations and the calls are normal.

Hopefully cisco will eliminate the spurious message sometime.

Are your E1 controllers clean of slips ? Do "show controllers E1".
