E&M does not collect digits

[jeremy.chang]

I have a Cisco 1760 with one VIC-2E&M module. I get the dial tone after dialing a access code. When I dial the called number , the 1760 does not accept the phone number and I still hear the dial tone .

Phone ---- PBX ---- E&M (1760) ----- Leased Line ----- PBX ---- E&M(MC3810)

The IOS version is 12.2(15)T and E&M configuration is

signal immediate

type 2

2 wire

How can solve this problem ?

My guess is your pbx is probably not forwarding the digits to the router.

Can you include

debug vtsp all

debug vpm all

debug voip ccapi inout

from the 1760 in millisecond

service timestamps debug datetime msec

Thanks.

I think it's a IOS bug !

It's ok after I changing a older IOS.
