I have this problem, when call is initiated from public number to my desk phone ( RDP number is set to my cell phone) , mobile connect would not initiate call to my cell phone number. I can call that cell phone number from my desk phone. Also mobility works when I call from one desk phone to another, call is ininitated to RDP cell number.
I believe that has someting to do with gateway sending redirect to provider, and provider ignoring that request ? Are there any settings that I can do on gateway/CUCM to hairpin that call on gateway ?
