No, there is
only traffic in the direction SIP->PSTN.
I'm not using the web interface, but instead the shell command
session.py
This is what it shows ... ( for the case when I call from
PSTN-to-SIP )
Total traffic: 20.48kbps/0bps/0bps (in1/in2/out)
Session count: 1
I think you need to look into your ser.cfg; it looks to me
like you are proxying calls only when they originate from NAT
-> non-nat and not from non-natted endpoints -> NAT.
I know that, I could tell from when UA sends rtp traffic directly to the
Gateway instead of sending it to the proxy. Is there something in the
sip/sdp headers that tells the proxy from where to get the IP of my UA,
so to be able to proxy the call ? Or, in other words, Why should calls
coming in from the pstn not be proxied ?
Here goes my ser, may be you can see something I'm not seeing ...
