Porting from one VOIP Provider to another

How easy is it to port a number from one VOIP provider?

As an example, could I move an AAISP VOIP service to another provider and keep the existing number?

Ask AAISP and your proposed new VOIP provider? Hopefully they will both say yes.
AAISP said I could port a number to them from Sipgate which I might want to do if Sipgate close their service as has been mentioned.

As I understand it AAISP are one of the very few who WILL NOT allow a VOIP number to be transferred out. Might have changed in the last couple of years

Interesting. If I have to leave Sipgate I will ask them about that before moving to them! They might not be so fussy about a number which was not originally theirs.

Checked with A&A - they do allow numbers to be ported out as long as they have a porting agreement in place with the other provider (which in the vast majority of cases they will)

My understanding, broadly under Ofcom rules, was that any provider that allows numbers to be ported (in) must also reciprocate (allow porting out).

That's interesting to know, I will probably be going from PSTN to VoIP sometime early next year after I get FTTP broadband up and running. For me the ability to easily port a number is an important feature of any VoIP deal.

For example, VoIPify https://www.voipify.net/pricing/ state that: "not all numbers can be ported but we have porting agreements with the most popular providers, get in touch to discuss porting to us."

Incidentally and if applicable in my case (?) a charge of £15 by voipify to port a WLR landline number to their VoIP service doesn't seem too bad.

That porting charge seems fine. Less than I paid a few years ago.

I used VOIPIFY (then port5060) to move two BT numbers across. I paid te fee and BT refused to port them. I eascalated it with their support and VOIPIFYtried again - successful.

Personally I like VOIPIFY as their international charges are excellent and they are a small UK based company who are always responsive.

I'll give them a call on Monday to check out the various costs involved in a move to their VoID service from WLR PSTN. Initially I imagine there would be one off costs including the need for new hardware but I'll cross that bridge when I come to it. Basically I just want a conversion from analogue to digital voice using a single handset, no additional features and no problems with porting my number.
