My client has a UC540 and a SIP trunk for incoming calls. Incoming calls go to a blast group then after the timeout the call should go to voicemail however the caller is receiving a message from the SIP trunk provider stating that the number dialled is not valid.
PSTN calls to voicemail are working - just SIP calls are affected.
I have taken debugs of voice ccapi inout, and ccsip all and these are attached. In example the called number is 0394281062, and the calling number is 0390240631.
Any suggestions please...........
