We have a customer wanting to move from Orcon Genius to BigPipe (sorry!) and they want to keep their landliine number and port it to a different VOIP provider (nothing to do with us).
We're having a bit of a discussion here about the best way to do this, and thought I would ask you guys to see what you think.
Normally, with traditional POTS+BB (say, from Telecom, Vodafone, etc), if the customer ports the voice before we move the BB, there is a danger their whole BB gets cut off and has to be reconnected with us which might mean quite a bit of downtime compared to a transition. So if somebody wants to do this we normally transition the BB first, but leave the pots in place for the customer to port it out at a time of their choosing.
BUT because Orcon BB is a requirement for Genius VOIP and it is delivered via a single naked connection rather than distinct POTS + BB, I worry that this might not work, and porting the BB will actually cut off the voice line first, meaning this customer might lose his landline number.
On the other hand, because the Genius VOIP is (hopefully) not a requirement for Orcon BB, porting the voice FIRST should allow the Orcon BB to remain without an associated voice number, and then the BB can be transitioned over to BigPipe VDSL.
Is this correct? Should we port voice first, then BB in the case of Orcon Genius?
