my SPA3000 is in Thailand. I config with voxilla with 2 stanaphone accounts: line1=account1 and PSTN=account2. PSTN to VoIP works great.
Here is what I am trying to do;

1) I have 3 users with 3 VoIP account and 3 different PSTN caller PIN ( userA account A, pin is 11 - userB account B, pin is 22 - userC account C, pin is 33). Each user needs to do PSTN to VoIP calls but they need to use their own account. How can I configure the SPA so that when userA call PSTN after he authentificate his pin which is 11. SPA will automaticly use account A to make that VoIP call. and when userB call PSTN and use his pin which is 22. SPA will use account B to make that VoIP call.

2) when I use SPA as gateway to make PSTN to VoIP call. The sound seems a little low. How can I ajust?

Any suggestion are welcome. I left my config below
