My Grandstream HT-701 won't support rotary dialing. works fine on TT but on any rotary extension, it won't dial out. it keeps crashing or I get an error message. all my phone except for my office phone are rotary... any idea on what I should do? other then changing over to TT...

The HT 701 should work as far as I'm aware. I've got a HT502 working here with no issues. The only problem I've had was with the make/break ratio of some British dials, as I explained further up this thread. Try adjusting that and your ATA might start accepting pulses.

Grandstream HT-801 and HT-812 work very well with pulse dialing. Please add them to the list.
They support tone from pulse "overdial", so they are actually sending tone events on pulse dials during call. IVR works.
They support neon message waiting indicator. They will pulse neon lamp with about 1s on/off cadence, pushing about 90V DC. Successfully tested with normal and colored neon lamp.


HT-801 pros:
powered by microusb cable, which is neat.
have rudimentary line diagnostics in firmware
as cheap as it gets for single FXS with pulse dial capability
HT-801 cons:
line makes annoying pop sound when goes off-hook or during pulse dialing

HT-812 pros:
dual gigabit ports
nice sound quality
dual FXS port
HT-812 cons:
cadence/tone settings are common for both ports (cannot be set separately, as other settings)
no line diagnostics in firmware - replaced with basic call accounting
basic 12v power supply
