VoIP Phones - Grandstream HT8xx: Difference between revisions

* There's a confusingly explained option under ''FXS Port'' labelled ''Use # as Dial Key'', explained as ''if set to Yes, "#" will function as the "(Re-)Dial" key''. If set to ''No'' the # key works as a normal key, if set to ''Yes'' it acts as a special key variously named ''Send'' or ''Dial'' which can be used as ''Redial last number called'' - but that'll be the last number dialled by the unit, not the last number dialled by the phone concerned. I set it to ''No'' to avoid surprises.▼

* Also under ''FXS Port'' are some options regarding Hook Flash. This corresponds to what the UK calls ''Timed Break Recall''. I set the option ''Enable Hook Flash'' to ''No'' - otherwise you can think you've hung up on a call by tapping the hook switch but you haven't (and your phones ring to remind you - so you pick the handset up and find the other party is confused too).▼

You can set up distinctive ring tones based on the calling number, and it even allows matching on part of a number. I use '020836xxxxx' to match calls from a number of exchanges on the northern edge of London (which is where your author lives). You can't match a E.164 number (+442036xxxxx) directly but under ''FXS Port'' is an option ''Replace Beginning '+' with 00 in Caller ID'' which changes +4420... into 004420... which can be matched.▼
