SIP SETTINGS/SIP ToS

The following options are provided to configure SIP ToS on the GXE5102/5104/5108/5116.
Firmware version 1.0.0.19
static NAT or PAT.
Configures the externally mapped TLS port when GXE is behind a static
NAT or PAT. The default value is 5061.
A list of network addresses that are considered inside of the NAT
network. Multiple entries are allowed, e.g., a reasonable set could be as
follows:
192.168.0.0/255.255.0.0
This is a global NAT setting that will affects all peers and users.
•
No: Use rport if the remote side requires it.
•
Force rport: Force rport to always be on. This is the default setting.
•
Yes: Force rport to always be on and perform comedia RTP
handling.
•
Comedia: Use rport if the remote side requires it and perform
comedia RTP handling.
Note:
"comedia RTP handling" refers to the technique of sending RTP to the
port where the other endpoint's RTP comes from. This can also be
rephrased as "connection-oriented media".
When turned on, the GXE will try to redirect the RTP media stream
(audio) to go directly from the caller to the callee.
•
Yes: Enables RTP Reinvite.
•
NoNAT: Allows media path redirection (reinvite) but only when the
peer is not be behind NAT. The RTP core can determine if the peer
is behind NAT or not based on the IP address where the media
comes from.
•
Update: use UPDATE for media path redirection, instead of INVITE.
Note:
Some devices do not support this (especially if one of them is behind
NAT).
