We use the 2760vn as a business router with a VoIP line provided by our ISP. Connection/call quality was always a bit dodgy, sometimes requiring a router restart. I assumed it was a factor of being on a fixed wireless service and didn't do anything about it.
I've recently moved to a new ISP (with a more stable fixed wireless connection) and problems persisted.
The ISP informed me that they've moved away from Draytek gear recently because their VoIP firmware is poor, causing issues like echo and failures to register SIP line etc.
Having read a bit of this forums sticky, it seems that misconfiguration is rife, so I was looking for an opinion by experts who've used Draytek VoIP gear.
Is Draytek's firmware flawed by design in any way? Or, with some tweaking of the config should a Draytek hum along with no issues? (pretty sure my ISP resells a basic 2talk service)
This is going to determine if I bin the Draytek and buy a Linksys router + ATA.
