Hello,
We have been doing this for 12+ years...
Something odd is happening.
We use Grandstream HT814 and HT818 most of the time.
Usually with an NEC SL1100 or SL2100 to provide the dial tone.
I have 2 customers...with the same set up.
1. SL2100
2. Grandstream ATA
3. Verizon FiOS
DTMF has gone wonky.
When a caller hits the auto attendant, the system doesn't recognize DTMF.
Calls time out to the operator phone.
This doesn't happen anywhere else.
And we have plenty of systems out there.
Any ideas for this?
I've tried forums, SL tech support...nothing solves it.
Thanks,
Ed
