No audio on US destined calls

[kjmj]

Hi,

I'm having trouble making calls to some US phone numbers. The calls connect and I can hear the party on the other end but they can not hear me. Even after repeat attempts, the recipient can not hear me. This has happend on my last two US calls, first was to (206) 441 XXXX and the second was to (615) 354 XXXX.

Now I can recieve calls from anywhere without any problems and can make calls a anywhere in Canada without problems. This NEVER happens on Canadian calls.

I'm using a Linksys PAP2T NA and the configuration was completed based on the tutorial on this site.

Thank you in advance.

Ken

This problem is still happening.

Any ideas?

I'd suggest a PM to fongo_neil or fongo_mike as this sounds like a call routing issue which both of them would be equipped to look into!

Thanks, I PM'd those guys earlier in the week and have not heard back. Is there anyone I could email directly at a higher level of tech support?

Just try running STUN (stun.callwithus.com) and activate "Nat Mapping Enable" and "Nat Keep Alive". This is often needed with the Linksys ATAs.
