Re: Cisco 2610XM voice T1 with PSTN T1 connect

Shawn,

this is a long shot, but it is based on my experience. I have played witht he 2600XM and most of them come with the H323 v.4 which, still has some unresolved issues with some other Telephony devices out there ( i am not sure who needs to catch up to whom). Based on your description, it could well be an IOS issue. I would recommand the following:

1) downgrade the 2600XM to IOS 12.2(5) for example, or any other IOS that doesn't have the new h323 v.4 (i belive anything prior to 12.2(11) will do). if the problem persists, then

2) turn on debug isdn q931 to see what you get. I will suspect something around the "bearer's capability not implemented" ISDN cause in the ReleaseComplete that the XM sends back to the PSTN switch.

if 1) solves your problem but you would like to use the rich features available with the v4 stack, then you might need to contact the ISP and CISCO to reconcile differences. I will guess cisco will tell you how to adjust some of the parameters on the XM's end to make it work.

Finally, let's know how you resolve this issue. I am pretty interested in the outcome.

hello,

thanks your reply,

about cisco 2610xm IOS, it have 12.2(8)T above now, no any 12.2(5) IOS. so I can't to downgrade.

becuase I use voice T1, is nonisdn, so I can't use any isdn q931... debug command to show anything.

we will contact cisco tac, how to reslove, if have any reslove, I'll tell your later
