CUCM integration with CME

[luqman_khalid]

(SIP Phone)1000004<---->CUCM(HQ)<--->c2921rtr<---->c2921(CME router)<---->3020005(SIP Phone).both routers 2921 are connected on gi0/0 via optical fiber.

number on CUCM(1000004)

SIP Phone on CUCME (3020005) . both phones ping each other successfully.

but first Problem is SIP Phone on CUCM side can hear my voice but i cannot hear voice of SIP Phone registered on CUCM.

secondly i cannot place any call from SIP Phone(3020005) Registered on CME to CUCM (1000004).

but CUCM(1000004) can call (3020005).

i think there is problem on CME end and whether i had to make any configuration on gig 0/0 in both routers..

configuration of CME side router is attached.

I asked because H.323 is not supported for a SIP CME.
