Hey DracoFelis!

It's great to get advice from a famous guy like you! I have read many of your articles about VoIP.

I can call test numbers from my SPA2102 device which is registered with Voxalot, but same test number fails (slow busy tone) when I try it at a Sipbroker PSTN gateway. I have only IP phones here, my calls to the PSTN go out via carriers.icall.net. I have had some issues with my credit card company not always understanding my DTMF tones. The problem may be that my DTMF tones are not getting through to the Sipbroker PSTN gateway. I called the time at *393-612 as a test.

My SIP device is a Linksys SPA2102. There are some settings for DTMF stuff, here is what it's got now:

DTMF Process INFO: yes
DTMF Process AVT: yes
DTMF Tx Method: Auto
DTMF Tx Mode: Strict

Should I change any of those?

Thanks,
boatman
