Optimize Audio Path - What does it do
 

Does any one know what the "Optimize Audio Path" on the Service Provider Page does? When I turn it on for sipphone I lose the audio from the call recipient. However, the call recipient can hear me. Knowing what this does may help me diagnose my problem.

Notes: I have symmetric NAT handling OFF as per the instructions. My ATA is an unlocked RTP300 which is attached directly to my cable modem and it has successfully registered. I have the same problem when this ATA is connected directly to sipphone.com instead of via Voxalot. I get bidirectional sound if I turn "Optimize Audio Path" off. And finally I get bidirectional sound when I am connected to Callcentric with "Optimize Audio Path" on.

Optimize Audio Path - attempts to have voice bypass VoXaLot
 

See this thread:

Thanks for the referral, I would have never found that post on my own. If I understand the jist of that post, then setting the Optimize Audio Path to "Yes" causes the SIP packets to bypass Voxalot entirely.

Well, yes....unless the other end is not properly set up to receive SIP invites (in which case it will likely default to proxying). Also some providers do not have very good support for this.

VoXalot does not get involved in the SIP packet exchange (if Optimize is working properly), but it still stays in the middle sending the two ends ReInvites telling them where to find each other.
