Hi,
I have a SER + Mediaproxy. I have not any problem
the call between SIP clients (behind or not the NATs)
but when I try to call to PSTN (via cisco) I only
have RTP traffic from SIP client to PSTN.
Summarizing, the path of rtp traffic would have
to be from:
up: SIP Client
----> SER ---> GW-PSTN
down: SIP Client <---- SER <--- GW-PSTN
but, really is:
up: SIP Client ----> SER --->
GW-PSTN
down: SIP Client
<------------- GW-PSTN
I use the command:
rewritehostport("212.xxx.xxx.xxx:5060");
when I match a geographic number.
The complete scheme is:
SIP Client ---- NAT
--------- SER+Mediaproxy -------- SIP Server --- GWPSTN
Some idea?
Thanks,
