Sending Fax problem


We have a netwrork RightFax and we are able to send Faxes to local numbers but not to an international number.

You can find below the configuration on the voice gateway and the output of " sh call history voice brief "

Kindly advice what does " Interworking 127 " mean and how can we solve this issue.

Could this problem be due to the E1 ?

Thanks in advance,

Sending Fax problem

Hi Mirna

Cause No.127: interworking, unspecified. This cause indicates there has been interworking with a network that does not provide causes for actions it takes; thus, the precise cause for a message being sent cannot be ascertained.

Please post your debug isdn q931 command output, with a failed call also post a with call that worked (Local)
