Telesis PX24U/PX24M Hybrid IP PBX systems try to have the media transport directly
between the connecting IP entities. However, in some cases like IP-TDM, TDM-IP,
SIP-H.323, H.323-SIP calls, this is not possible or efficient. In such cases, switching
and media proxying capabilities in Telesis PX24U/PX24M Hybrid IP PBX systems
route calls from one side to the other.

xSIP (eXtended SIP) protocol has been developed by Telesis. The main purpose of its
