SIP traversal for an incoming session of an
Ingate SIParator® (image below):
- SIP signaling/request for media session with an internal user comes in on a dedicated port (usually 5060)<1>.
- The SIP registrar is consulted to determine on which private address
the recipient is located and the signaling is forwarded to the
recipient<2>.
- Once the two clients have agree that they want to set up a session the
SIParator® sets up NAT
and allows RTP streams through UDP ports<3> (port numbers as
agreed during setup) and allows media to flow<4>.
