DTMF tones

[VOIPoTim]

Support had put me on these settings before you posted them and I am still hearing the tones. Oh, and I have rebooted the ATA several times.

Out of curiosity, how long have you had STUN on? Depending on the network setup in some cases STUN can force the audio to be routed directly instead of being proxied regardless of what we set it to do.

Has it always been enabled or was it enabled around the time this started?

If STUN wasn't on for a reason, let's try disabling it (and rebooting) and see if that solves it since it being disabled will make sure the audio preference is followed.

Although rare, its too bad DTMF couldn't be outside the normal vocal range.

Don't think it can be since DTMF has to be in the voice band in order to work..

The PSTN was engineered to carry just the normal vocal range; tones outside that range would be lost or mangled in transmission.

So what I'm wondering is: if hearing certain voice patterns in the incoming audio stream can fake the ATA into think a DTMF tone was present, wouldn't you think configuring the channel for RFC2833 should prevent that? After all, if you are telling the ATA that the other end will send DTMF either via RFC2833 or SIP INFO, it shouldn't be looking in the audio stream for DTMF, no? Or am I missing something?

[dswartz]

Ah, my apologies then. Sounds like two different problems?

Just for the record, I too have experienced hearing DTMF tones when my mom calls out from the VOIPo line to my POTS line at my office. It is irritating and I too would like to know how to solve it.

Also, mostly when talking to someone on a cell phone, the person on the cell phone claims to hear an echo of their own voice. These are the only problems I've had though.

Generally, the cell phone echo problem you mentioned might be helped by turning down the volume on the cell.

Conversely, you might ask support to turn down the transmit and receive levels in your adapter.

You can do this yourself in VPANEL.

I have had the echo crop back up again. It seems to come and go.
