Source notes citing this source

• The Kamailio topoh module hides topology by encoding the Via, Record-Route, Route and Contact headers, and optionally Call-ID, without any changes to the routing script. in context
• Kamailio topoh encodes with the mask_key secret; servers sharing the same mask_key can restart without affecting ongoing calls, and mask_callid defaults to 0 (Call-ID not encoded). in context
• Kamailio's documented modules cover the main functions of an SBC-front or carrier-edge role: dispatcher for load balancing and failover, topoh or topos for topology hiding, and rtpengine for media anchoring and SRTP or ICE interworking. They are separate modules that the routing script composes; there is no single SBC feature. inferred in context
