[asterisk-users] DTMF Issues

[Barton Fisher]

I have a block of DID's that I ported to Vitelity about 7 days ago.  The 
problem is if a POTS caller dials into the system, his dtmf is not heard 
at READ() or Background() while a prompt is played.  After the prompt is 
finished, then dtmf is heard.  I've been working with their support, but 
it still not resolved. SIP callers are not effected.

Yesterday, I purchased a DID from Flowroute.  The setting are the same 
as Vitelity.  And amazingly, this DID works perfectly. This to me would 
indicate the problem whatever it is, is Vitelity or its upstream 
provider. - Am I right here??

Also, I have other DID blocks that have been with Vitelity for a while 
that do not have this issues.  I'm told the upline carrier is the same.

So I'm reaching out to you guys to give me ideas of what could be 
causing the problem and how I can resolve

Thanks, Bart
