We are experiencing problems when we try to forward directory number on our IP Phones to our mobile number. Attached is a isdn q931 debug showing a call coming into IP Phone extension 7563 which is than forwarded to mobile # 07962354000.
I've read in other post that the calls should not Plan: ISDN and Type: National in UK. I wonder if this is part of the problem. FYI - this is a H323 GW.
When calling the mobile directly from a phone the call goes through no problem.
Any ideas to what may be causing this issue?
Thanks in advance.
