What is needed for VOIP?

(1/2) > >>

broadstairs:
I am having to start looking into this because TT dont (yet) supply VOIP, so I have a few questions.

1. Apart from an internet connection obviously what do I need to connect my house DECT phone to VOIP? What are the options?
2. Can I have FTTP installed alongside my existing copper connection?
3. Can I use VOIP over any ISPs internet connection or do they have to support it?
4. I assume that if I transfer my existing number from TT to VOIP that will terminate my existing connection and contract. I really need to keep my existing number.
5. Once VOIP is working can I redirect calls to my landline to my mobile phone? Useful if I'm out or away.

Well that is all for starters, I'm sure loads more will come out as I progress.

My set up WAS broadband and phone with VM.
BT copper left in place but not used.
I then migrated to BT FTTP with Digital Voice. BT copper left in place but not used.
I use BT supplied handset that uses the Smart Hub as a DECT base station. AFAIK the only way to use BT Digital Voice is with the Smart Hub as a base station.
Other VOIP would use the broadband connection with a suitable adapter.
I have transferred my land line number from VM to BT DV. Bit of a hassle but we got there. I don't know about other VOIP providers.
Whether BT will provide a phone service down an existing copper line I don't know.
Other DECT handsets can be registered to the Smart Hub (not just BT ones).

Its been mentioned that AAISP can redirect VoIP to mobile, but then you can also setup SIP on your phone and access VoIP over mobile data.

VoIP gives you a lot more flexibility in the long run as its just another service over the Internet, ANY Internet connection.

I believe the only time it becomes a problem is for incoming pure IP calls, that will only work correctly if everything is configured exactly right.

1. Apart from an internet connection obviously what do I need to connect my house DECT phone to VOIP? What are the options?
Depends on your DECT system.  In my case I bought a new Gigaset base that supports SIP as well as land line, and which was compatible with our existing DECT handsets.   Otherwise to use your existing gear you need an analogue adapter (ATA) to convert from IP to POTs.  I dislike these as you often lose function in the conversion.

3. Can I use VOIP over any ISPs internet connection or do they have to support it?
Should be able to use any line, the performance demands are quite low in terms of bandwidth, under 100K for a voice call.  Ideally you want the latency to be as consistent as possible.

4. I assume that if I transfer my existing number from TT to VOIP that will terminate my existing connection and contract. I really need to keep my existing number.
Normally a number port ceases the existing line, however A&A now have a process to port a number off a BT (Openreach) line without the line ceasing.  Not sure on the options of your TT line is actually native TT and not OR for the telephony side

5. Once VOIP is working can I redirect calls to my landline to my mobile phone? Useful if I'm out or away.
Depends on the SIP service, in most cases yes.

1. Depends on the handset.

2. Yes you can. OpenReach allow it. Some individual ISP's don't support 2 services on the same account so you may need to pick another provider for the FTTP or sign up as a new customer if your current ISP doesn't support both together. Talktalk don't support 2 different products on the same account/email. So the FTTP needs ordered with a new email address if you wish to keep both.

3. Yes. The ISP doesn't need to support it. VOIP should work over any internet connection.

4. Yes it will.

5. Depends on the VOIP provider. Some support that and others don't.

If you wish to stay with Talktalk, move to FTTP and keep your number, my advice on another thread still works perfectly.

Order the FTTP and wait till it's live. You need to do so as a new customer (for reasons explained above).
Once you are satisfied the FTTP is live and working, migrate the landline number to a VOIP provider.
10 working days later your FTTC will cease.
You now have the benefit of your number not being tied to your broadband.
