I have this scenario:
One CallManger version 188.8.131.5200-2 and two H323 Gateway (Cisco 3845)
One H323 Gateway is connected to Alcatel PBX and the other H323 Gateway is connected to PSTN.
Alcatel PBX have extension 3xxx .
CallManager have exension in the range 1000-2499 (internal IP phone).
Extension 1xxx,2xxx can transfer to extension 3xxx but external call come to the PSTN not.
When a call comes to PSTN and I want to make the transfer to extensions 3xxx, call drop and CallManger give a busy signal.
