Perhaps I'm going down path and maybe this solution will not work..
I have a CM 4.X system at location A that uses a local H323 gateway to connect to the PSTN....
I have a CUCM 5.X system at location B that uses a local H323 gateway to connect to the PSTN....
I can dial over the trunk from location A to location B using the 4-digit local extensions... IE Location A is 4XXX and Locatino B is 6XXX.. so the inter-office calling is working great.
However when a call from the PSTN at Location A , is answered by a phone at location A (4XXX), and is attempted to transfer to DN at Location B (6XXX) the call is immediately dropped when Location B picks up the handset.
I've tried setting up the Call Class as OffNet and OnNet... but I just can't seem to get the PSTN calls to tranfer while the internal calls transfer and router just fine....
I appreicate any feedback.
