1751 - "incoming-voice" command not found, IOS Version 12.2(8)T1

1) I am unable to find the "incoming-voice" command on this IOS, should I upgrade to another version or is it enabled by default?

2) I manage to get calls from the PABX to the router, but am unable to place calls from the router to the PABX -

ISDN q931 debug:

"ISDN BR2/0: RX <- INFOc sapi=0 tei=65 ns=1 nr=2 i=0x0801825A080380E070"

"RELEASE_COMP pd = 8 callref = 0x82"

"Cause i = 0x80E070 - Mandatory information element missing"

Any ideas out there?

Lutz.

Re: 1751 - "incoming-voice" command not found, IOS Version 12.2(

Incoming voice command should be on that IOS if you are running IP PLUS Voice/VOX feature set. Nonetheless your PBX is complaining about some information element that is not present in the setup message. If you had posted a complete setup message I could take a guess at what that may be. You need to contact your PBX vendor as to what IE that is.

I had the same problem. It's reported as a bug in 12.2(8)T and 12.2(11)T. I've upgraded the system to 12.2(13)T1 and the command is there.
