Repeat with "debug isdn q931" and "debug ccsip message". Do not enable any other debug.

Output will be so reduced that you will be able to read it and will not require attachments to be posted.


If you are using asterisk or similar, note CME on the router does a  much better job especially when used with cisco phones.


Note if you should not use

isdn bchan-number-order ascending

I removed the command "isdn bchan-number-order ascending"

and this is the output of  "debug isdn q931" and "debug ccsip message"


from cellphone there are not sip message


the 2 sip server are two Interactive Voice Responder

You must have some other config not included above.

direct-inward-dial is always required.
