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.

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.
