[Spce-user] Source IP and port change by endpoint

I have a situation where rtpengine is use following way...

EndpointA -------------->Openser(rtpengine)------------->EndpointB (Gateway)

1- EndpointA initiates call and gets Session progress and media starts to
flow no issues so far.
2- In some situations EndpointB changes its source IP and Port and starts
sending media to rtpengine.
3- As rtpengine constantly learns source IP and Ports , it starts
forwarding media received from EndpointB to EndpointA but this time
Rtpenegine also changes its own source port for stream

EndpointA ignores media from this new port and we hear no voice afterwards.

Is there any setting to force rtpengine to use old port?
