Raja,


The majority of RTP one way transmission problem are down to IP routing issues.


The RTP stream should be from the CME phone ip address to the CUCM phone IP address.


In your case the issue of RTP one way direct is from CME PHONE ----> CUCM PHONE.


You weill need to start checking the IP connectivity and routing tables

from the VLAN for the CME phone to the VLAN for the CUCM phone


May be use something simple like

tracert from the CME PHONE VLAN

Alex.
