Hi guys,

Sorry if my question seems a little weird. I'm totally new to VOIP and SIP!
I want to know if a SIP server acts as a central server to transfer VOIP packages from/to users, or it's just a registration server. I mean for example suppose that user A is in Asia, user B is in Europe and the SIP server is in the US. Now, when A calls B, does it mean that ALL voice traffic goes from Asia, to US and then to Europe, or just from Asia to Europe?
The problem I have is that I want to make my VOIP environment somehow that when A calls B, it uses direct connection to B. I don't want the SIP server to play any role in this voice connection other than registering that A & B are talking. Is it possible?
This is because my SIP server have very limited bandwidth :(

Thank you in advance for your help

AQuA - Audio Quality Analyzer

AQuA provides precise and extensive audio quality testing that can be easily brought to your company's own hardware enabling your monitoring server to graphing MOS/PESQ values for various voice termination locations.

Many companies are using this product to test and monitor voice and audio quality of conference bridges, carriers and VoIP links. Typically companies that provide telecom solutions have automated "test dialers" to test networks of conference bridges, carriers, terminations etc, and the system is able to place test calls and record them to for example a wav file. And the only thing that is missing to obtain full test sequence is an ability to automatically compare wav files to determine if there are any significant audio quality problems.

AQuA voice quality solution is designed exacty to fit these needs. In case of Asterisk for example voice quality monitoring using AQuA is implemented in the following way:

1. Originate a call on the monitoring server using Asterisk manager interface to a server which is running an echo application.

2. Monitor both inbound and outbound legs of the call and save them as wav files.

3. Use AQuA (Linux or Windows version of the software) to compare the wav files.

This approach is quite effective as one does not need to purchase additional hardware thus utilizing existing infrastructure. We sincerely believe that many other companies will find AQuA product useful, competitive and cost effective solution for audio quality testing and monitoring.

Thank you very much for your time and we are looking forward to hearing from you!

Best regards,
Endre Domiczi
