[Serusers] how does a b2bua help billing

[Shaikat Mahmud]

Hi
	Did you see any RTP flow from or to your Media Proxy? Did you
analyze the sip massages? Please verify that, Media Proxy is getting the RTP
flow from both ends and it is relaying these to the receiving ports. You can
test it using Ethereal. I don't know about Vovida, but if you can give call
to any other UAC, then problem is in Vovida configuration.

Does the following scenario work?

Uac1 -----> NAT DEVICE -----> SER with Media proxy--------------> uac2.

If this scenario works, then you should check the Vovida's configuration.
Otherwise you are using a bad ser.cfg.

Hi Shaikat I'm deploying a similar environment like you describe but I'm 
using Vovida instead Asterisk as B2BUA. I'm using mediaproxy for NAT 
traversal support and I'm having troubles when I try to place a call.
I'm not receiving any audio but the call is established. Do you have any 
idea according your experience?
