[Asterisk-Users] DTMF detection

[Tom Vile]

I have been battling this problem for 2 months with no resolution as of yet
with TelaSIP. I am told that it is a provider problem(Level 3) because all
TelaSIP is doing is passing the call directly to them once the call comes
through.

Anyone else having this issue with TelaSIP or Level3?
