Help, basic opensips setup not working & volume too low

apenk
Hi,

I have two problems with opensips. I really need some solutions for my problems.

First Problem: Voice Volume Too Low
I try to set up opensips in a home environment. The opensips use MySQL authentication.
The components are two android phones (with softphone), one wireless router, and one server that run opensips.
I connect the server to LAN port on wireless router, and android phones connect the network via wifi. It worked well.
I mean, the phones can talk to each other. But the problem is the voice volume that too low. I did not use any media server.
I know I used opensips for proxy, but how can this happened? And what should I do? Because I could not find any documentation that said about relation between opensips and voice volume.

Second Problem: Opensips Basic Setup No Working
When I connect the server to WAN port on wirelss router (of course I changed the IP address), it didn't work well.
The phones could register to opensips, but their calls were not reaching. It said "connecting..." and then timed out.
Should I change the configuration? If yes, what should I change?

Please help me.
Thanks in advance.

Kind regards,
Apenk Satria

Hi,
 
 Because I could not find any documentation that said about relation between opensips and voice volume. 

I doubt you'll ever find any document of that sort, openSIPS is for SIP and not for RTP thats why its not openRTP. So the issue is with the phones which are sending the audio directly to each other w/o going through the server. You can verify this by taking pcap/wireshark/tcpdump traces of calls on server.

but their calls were not reaching. It said "connecting..." and then timed out.
Should I change the configuration? If yes, what should I change? 

Without looking at your basic configurations I can only assume that your REGISTER method has handled NAT whereas the INVITE method receives the traffic from your home network with a private-ip to be replied back to and honestly it do so. While phones are looking to hear from the server , the server is trying to send the packets back to an unknown private network destination !!. 
Phones(192.168.15.x)---->Router(PUBLIC.IP.A)----->(PUBLIC.IP.B)OPENSIPS~~~>(SENDING TO PRIVATE IP UNROUTABLE FROM INTERNET)
To troubleshoot it better please take sip capture for calls you're making and paste these here.

Again the above is my assumption. You may need to use NAThelper module for this. For a clear picture please post sipgrep/ngrep/tcpdump traces.

Regards,
Sammy.
