Have you tried changing the plan and type of the call. You can do so with isdn map address command under the channel. I can work with you in the lab on this.

Hi Issam
The release is coming from the switch. Have you tried changing the plan and type of the call. You can do so by using the isdn map addess command under the D channel. I can work with you on this in the lab.
