One way conversation from CUCM to remote location

Whenever I route traffic for network 145.47.184.0 to satellite link 172.20.1.3 which is bundle with other links using E1 as shown in the config attachment below there will be one way conversation I can hear from that end but they can't hear me, but if I route the traffic through another secondary link to the using E1 on different router there will be two way conversation. What could be responsible for this problem

might be routing issue?

The two links to the remote locations are PVC with similar IP routing table

this same router serves as gateway to CME in another remote site that is configured on subinterface 0/0/0:0.1, and the there is two way traffic at both end

Re: One way conversation from CUCM to remote location

when there is one way voice traffic the problem is usually a routing issue. If they cannot here you, then your traffic doesn't know how to reach the subnet their phone is on. Can you ping the phone's IP address (with a source address of your voice subnet) of which they cannot hear you?
