[OpenSIPS-Users] New MediaProxy release 2.6.0

[Nick Cameo]

Hello Saul,

I was looking at a SIP trace on an active call as I type this. Actually
we only need the public ip address advertised in the SDP payload
for the device which is behind NAT (ie, listening on a private ip address
with 1to1 port forwarded mapping done on the router for the public ip
address).

The advertised address of the VIA and Contact headers are what shuffle
between public and private IP addresses. This of course is the handled
by OpenSIPS as it already does so eg:

Via: SIP/2.0/UDP 74.71.33.154:5060;branch=z9hG4bK4.0.
Contact: <sip:74.71.33.154:5060;did=5f7.8d>.

Via: SIP/2.0/UDP 192.168.0.100:5060;branch=z9hG4bK596;rport.
Contact: <sip:192.168.0.200:5080;did=5f7.8d61>

In summary, can you kindly direct us to the much needed documentation on how
to install, configure, and run an OpenSIPS+MediaProxy instance from behind
a natted 1to1 mapped instance.

Only upon doing so will I resume doing jumping jacks which I have
halted indefinitely
until further clarity.

Kind Regards :)

Nick.
