Cisco 803: DDR B-Channel Identification problem

I'm using a 803 for get into a local ISP, when establishing the connection, the link is dropped after 2 seconds. From the log, everything seems to be ok, the only error in the conversation proccess is the identification of the B-channel, find below the log:

Any ideas on where should be the problem.

Re: Cisco 803: DDR B-Channel Identification problem

Sounds like you are running into bug CSCdp76631 which is present in 12.0.7T. Please check your IOS and see if you are running this IOS. This bug only presents itself when placing outbound calls. Inbound works fine.
