When Mobile Agent local/remote CTI ports are located on different clusters and a SIP trunk is used to connect the clusters, "MTP required" must be checked on at least one side of the SIP trunk in order for Mobile Agent to Mobile Agent calls to work between the clusters. H.323 trunks do not require an MTP for Mobile Agent to Mobile Agent calls
