HT801: only for forwarding VoIP calls to non-VoIP number?

I have Hyperoptic broadband (1Gbps) and use the Hyperoptic VoIP service built into the Hyperoptic Hub for my landline.

Until recently I had a DECT phone connected to the Hyperoptic Hub, but a power surge killed the DECT base station so I've now configured the Hyperoptic VoIP service to forward all incoming "landline" calls to my mobile telephone, and this actually works really well to the extent that I don't plan on replacing the analog phone.

However for unrelated reasons I'm now thinking about replacing the Hyperoptic Hub with a third party router, but not all of the third party routers I'm considering support VoIP functionality.

So my question is this: would a Grandstream HT801 (while using the Hyperoptic VoIP server) be able to unconditionally forward incoming "landline" (VoIP) calls to my mobile phone, exactly as the Hyperoptic Hub already does - ie. with caller id etc.? There would not be an analog phone connected to the HT801 - it just needs to forward the incoming call straight to a mobile number.

As a solution I suppose this might be overkill - perhaps a software client on a Raspberry Pi would work just as well, but to be honest I really want something that works out of the box with minimal fuss!

Thanks in advance!

Where is the forwarding actually done?

Is it in the hub? Or on the VOIP providers server?

To be honest I'm not entirely sure - I had assumed the Hyperoptic Hub performed the forwarding function (note: I'm a VoIP novice which is another reason why I want an out of the box solution!)

Tomorrow (Saturday, as it's too late now!) I'll power off the Hyperoptic Hub and place calls to the landline number to see if they still come through to my mobile number.

If the landline calls continue to be diverted to my mobile phone without a Hub then the call forwarding must be being handled by the Hyperoptic SIP server which would mean an ATA may be unnecessary - I'd only need the Hyperoptic Hub should I ever need to reconfigure the server settings.

However, without a Hub (and therefore without a client) could my SIP registration to the Hyperoptic server eventually timeout? The Hub settings page for the VoIP service mentions a "Registration interval" of 3600 seconds. So maybe I'll be logged out after 1 hour and no further calls will be forwarded...?

Any call forwarding will be done on their SIP server, rather then the endpoint (customer router).

I know, the idea was to make the OP think about it; which has happened.

Do you know your registration details for your Hyperoptic VOIP service, or if not will Hyperoptic tell you these details?

There are apps like Csipsimple which will run on Android mobile phones and which can register with VOIP providers.

Some VOIP services such as Sipgate allow you to have more than one device registered and ring both phones. Otheres such as Voipfone don't allow this. You could ask Hyperoptic what they do.

The registration interval is how often a device tries to re-register rather than what the service provider does. If a device does not reply to an incoming call, I would expect the service provider to follow its procedure for phone not answered.

Check. But looks doubtful…

You could always port the number out to another VoIP provider and use your own gear.

Thanks both - disconnecting the Hyperoptic Hub causes any calls to my "landline" to result in an engaged tone, so the Hub appears to be required.

Yes, Hyperoptic will give out the registration details freely - that's not a problem. I know other Hyperoptic users have the HT801 working with the Hyperoptic service - I really wanted to know more about the functionality of the HT801 with regard to call forwarding (aka call divert) but we seem to have got off the beaten track for which I apologise.

I thought this VoIP sub-forum was the more suitable place to ask about the VoIP hardware (ie. HT801) rather than in the Hyperoptic sub-forum but in hindsight maybe that's what I should have done!

Yeah, however for the sake of a £40 device (approx cost of a HT801) I figured that would be the easier option particularly as I'm keen to keep my landline number and don't want to have to port it out again (plus I already pay for the Hyperoptic service, and am happy to continue for the price they charge).

Thanks! I've now determined that if the Hyperoptic Hub is disconnected then callers to the VoIP landline will get an engaged tone, presumably as there's no active "client" (user isn't logged in/connected)?

Thanks, that's interesting option but getting rid of the Hyperoptic Hub entirely was my main objective, although I guess it could always be a Plan C or D if nothing else works out!

The HT801 does work with the Hyperoptic service, so porting out shouldn't be necessary, I really just wanted to know the capabilities of the HT801 with regard to call forwarding (irrespective of Hyperoptic as the service - I guess maybe mentioning Hyperoptic was a mistake in hindsight!)

Thanks for all the replies, I think I'll ask on the Hyperoptic sub-forum where I know at least one user has an HT801. I'll update this thread if I'm able to reach a conclusion!

I think a Cisco SPA112 will forward calls as you want. You can download the full manual if you want. What I think you need is the User 1 (or 2) Call Forward Settings, Cfwd All Dest:

I have one which selectively forwards certain calls to another number.

It can also forward calls after a configurable delay if they are not answered.
