I’m trying to set up a SIP and RTP proxy server to provide sip trunks to
other SIP servers and PABX. The trunk to the PSTN will be provided by an
other SIP server. This server will only handle signaling and rtp streams
from our server. To test the configuration I’m using a softphone (eyebeam
1.5), a cisco 7912 with SIP IOS, both logged in on my own SIP server, and a
mobile phone as a PSTN client.
Above shown in a diagram
.

The following occurs:
1. When I call from the softphone (eyebeam) the the Cisco 7912 the call is
established correct. As far as I can debug the clients are forced to use the
mediaproxy running on our server. This also works the other way around.
2. When I call from PSTN to a SIP client, I can only hear audio from the
PSTN on the SIP client.
3. When I call from a SIP client to the PSTN, I can only hear audio from the
SIP client on the PSTN client.
So, my conclusion is:
When a call is setup from or to the PSTN network, audio is only working from
the client the call is originated.
Below is the configuration from our SIP server and The Mediaserver.
Please help me out here
. Let me know if you have any questions or need more
information
Kind regards,
