Description (partial)

After the transfer is completed we can see the media exchange signaling is looping on all the servers in the cluster. Muliple OLC/OLC ACKs are sen to from the phone as well on the H323 Trunks. On the SIP trunk we can see Re-Invites with SDP changing the port numbers.
When pressing the ? button on the phone send/received packets are looping from 1 to 0.

Security (encryption) configured on all the devices in the topology (including trunks), SME does inter-working between h323 and SIP.
