CME : Sip to H323 Problem

HI all

CUCM-------------WAN-------VOIP-------------------------CME-----Pots

Above is my Scenario where I have  2 Remote site using CME and HQ CUCM 7. For toll bypass I am using SIP Trunk to route traffic from HQ  to Branch to make local call from Branches. 1 of 2 sites its working ok , But the Second Site although the calls are routing via SIP they unable to go out to POTS dial peer.

I have tried to compare the configs .the only difference from the workin site is that on the sip conf I have extracted the following, Site A does not Support the following commands.

NOT Supported

sip

  bind control source-interface GigabitEthernet0/1

  bind media source-interface GigabitEthernet0/1

( I have enclosed Debug from CME not work)

Could this be the problem

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip
