[Serusers] Problem/Question regarding mediaproxy

[Ronald Voermans]

Hello,
 
I'm using Ser in combination with Mediaproxy. The situation is as
follow: My SER has a private ip address (10.254.254.1), and my UAs also
have private IP addresses, they can all see SER, and SER can see the
UAs. Next, our company has a Voice Interconnect with a telco. (it's
using Cirpack as softswitch). SER can see Cirpack and vice versa.
However, the UAs cannot see the Cirpack. So I want to use Mediaproxy to
overcome this. I can make outbound calls, but when calling inbound, I
sometimes have one-way-voice of no voice at all. I think the problem is
related to Cirpack, but I have a question thouh:
 
 
- When calling mediaproxy, how does mediaproxy decide which one is the
caller and which one is the called? Is this based on the From and To
header? Because, if i call from PSTN -> SIP, i get serveral thousands
(!) of messages saying that the called person signed in (no caller signs
in in mediaproxy). This could be due to the fact that the from and to
headers are incorrect.
 
My ser.cfg is the one from onsip.org (pstn with nat). I can post
configs/traces if someone needs them!
 
Regards,
Ronald
