[asterisk-users] vegastream 50 FXO DTMF Problem

[Peter Doyle]

Hi Issac,
I would double-check the dtmfmode=inband thing, just to be 100% sure.
We've never been able to get out of band dtmf working with the vega and
asterisk, so we just use inband and it works well enough.

With our setup, the vega doesn't seem to strip out outgoing inband dtmf
tones, so if asterisk sends them inband, it seems like it should make it
to the PSTN.  That's why I think it'd be valuable to just verify
asterisk was actually sending inband dtmf.  I'm assuming the link
between asterisk and the vega is using an uncompressed codec like
g711a/g711u, otherwise maybe codec compression could be distorting the
dtmf tones, making them unrecognizable to the equipment at the far-end.

Here's the appropriate sections from our sip.conf:
[vega]
type=user
dtmfmode=inband
disallow=all
context=from-pstn
allow=ulaw

[vega-gw]
type=peer
host={ip address here}
dtmfmode=inband
disallow=all
context=from-internal
allow=ulaw

Then in the vega web setup, under media, we set the out of band DTMF to
"0" (off) for g711ulaw (which is all we use internally, and asterisk
translates for other codecs).  

Hope that helps.  It atleast was the solution for us
Thanks
Pete

Thanks Pete,

I did try dtmfmode=inband and it did not work for us.

Hi Issac,
If I recall correctly, out of band DTMF didn't seem to work for us on
our Vega 50 (atleast not when using the Vega with Asterisk).  We had to
tell Asterisk to use dtmfmode=inband in our sip.conf.  It didn't seem
like we had to change any settings on the Vega, because it was sending
both inband and RFC2833 when RFC2833 was selected (for incoming DTMF).
This is all from memory, so hopefully its correct.

I'm headed to work in a few minutes here, where maybe I can see our
actual config and send it along.
Good Luck!
Pete

P.S.  How has your experience been with the echo cancelers?  Are you
experiencing much echo at all?  That's the one thing we're still
struggling with. Thanks

Asterisk is sending the DTMF as we can see in ethereal but the Vega is
not sending them out. We did try the debug before ethereal but the tech
at VegaStream insisted we will need ethereal to troubleshoot this.

How do you mean it does not recognize them? By the routing not working
properly?

Or by not outdialing properly?

No need for ethereal, just turn on sip debugging and it will display the
messages for you, just like * will.
