DTMF (touchtone) passthru failing

US RC Office Standard

I have noticed in the last 2 weeks a high incidence of failure of DTMF going through on outbound calls from my VVX-410.  Audio quality if fine and initial dial if fine.  But if I call into another provider phone bridge (Webex, Join.me etc) I will sometimes have to enter my access code multiple times and have had a few instances of having to hang up and redial the number.

Anyone know if RC is using Inband or RFC2833 for sending through post connect DTMF signals?  If InBand, have there been any changes to the compression CODEC used for calls? (I believe Office Standard uses G711 as it is not HD Voice.)

I haven't had any issues, but full disclosure, I've only been on RC bridges - not WebEx or others.  However, I do have several locations on different PBXs and I made some test calls to retrieve messages (via touch tone) all with success.  Let's see what others come back with...

Barry, I'm trying to get some info on the Codecs, I don't think there have been any recent changes.  Have you noticed that there are specific numbers where it tends to work, or always fails?  If so, you may want to open up a support case and include the time, date, and number you are calling from, and too, in the ticket.
