[Spce-user] no voice or video register ok

[Daniel Grotti]

Hi Michael,
it seems an RTP issue. A can call B, B rings and can pickup, but then no 
audio. Is this the situation?

Please check the following parameters in your Domain preferences and 
make sure they are set to the following values:

1) use_rtpproxy = Always with plain SDP
2) rtp_interface = ext
3) transport_protocol = transparent

If yes, then it could be a network issue, RTP stream cannot flow 
properly from A <-> SPCE <->B.
To investigate that, you would need to check a SIP/RTP trace. You can 
use command "sngrep -r" to make this trace, and see why RTP cannot reach 
the end parties.

Daniel

All I want to do is to use a number of sip phones communicating with each other. I can register an entrance door station and a mobile phone to communicate with the server. I can also ring from one to the other, with the phone being connected to either the internet ( via NAT from the service provider) or with a local IP. ( so i would not think there is a NAT issue). However, I fail to be able to communicate with either voice or video. I can ring, I can pick up from either the phone or the doorstation but there is no communication.
