strange problem of caller id

When i dial outside number i-e any PSTN number the call-id information will display a wrong number on the reciever end, lets suppose my number is

7551234 and on remote phone number shown be 7551234 BUT it will show 7554455.

these both number are valid PSTN numbers they are mapped to internal extensions by means of cucm 5.1, while using FXO ports,

PSTN ----------------------> 7551234 ---------------->FXO 1/1/3---------->Voice Gateway (MGCP) ------------------------> cucm 5.1 -------------------------> 4111 (internal ext.)

PSTN ----------------------> 7554455  ---------------->FXO 1/2/1---------->Voice Gateway (MGCP)  ------------------------> cucm 5.1 -------------------------> 4122  (internal ext.)

7551234 = 4111 <-- (did extension, partition and CSS)

7554455 = 4122 <-- (did extension, partition and CSS)

for incoming caller ID information both of the PSTN numbers are configured with explicit call-id information and dial-peer are removed under mgcpapp.

configured h323 pointing towards relevant extensions.

I have checked everywhere in call manager and voice gateway like how come always 7554455 will be displayed instead of 7551234...

but if someone dials from 7554455 there is no problem at the recieving end it will show corrrect number that is 7554455.

why is 7554455 messing up the outgoing call id info of 7551234, how to slove this problem ?

Anyone would like to give a clue?
