[Serusers] Asymmetric UA & mediaproxy

[Adrian Georgescu]

1. Don't think  about making your UA asymmetric, make it symmetric
2.  I t is possible to use Mediaproxy with your asymmetric client but 
you would still need to set port forwarding in your NAT device so stick 
to point 1
3. Symmetric means to use same port for sending and receiving data

Hi

Sorry if this is already answered, but i've search the archives and
couldn't find what I'm looking for.

Basically I would like to have the following scenario:


UA1 asym --> NAT/Firewall --> Ser/mediaproxy --> PSTN Gateway

PSTN Gateway is a Quintum box, we already have several of this, and it
can only support asymmetric rtp, that's why we are looking at mediaproxy

I develop the UA1 myself, and can support both symmetric or asymmetric
rtp.

My question, is this possible with Ser/mediaproxy? If it is, could
somebody give me pointer on how to configure Ser with mediaproxy

Currenty I have the call goes to the pstn gateway but no voice on each
side.

Another question, how do you know if the sip signalling is asymmetric or
not?

Thanks,
Fikri
