At XSTRA we have had years of experience porting the numbers of our Clients. Here is a list of the steps that XSTRA usually undertake and this process can take between 4 to 12 weeks.

1 Obtain copy of Clients telephone bill/invoice
2 Submit a Port Number Validation (PNV) against all of the numbers on the bill/invoice
3 Get results back from PNV and based on the results from the PNV, XSTRA submit a Porting Form with AAPT to port all of the numbers identified on the PNV
4 Setup Cloud Based PBX with trunk to XSTRA’s CTS
5 Pick a temporary number(s) from XSTRA’s number pool and assign it to the trunk and change the inbound route for the trunk to point to the new PBX
6 Setup all of the phones and extensions and setup call flows on the new PBX
7 Setup the new numbers that will be ported on the new PBX in preparation for the porting completion
8 Exchange based divert of inbound calls from old carrier to temporary number(s)
9 Client is now using the new phone system
10 Setup the new numbers on the CTS
11 Wait for porting process to complete
12 Let Client know the date and time of the porting cut-over
13 Test PBX after advised cut-over from multiple carriers
14 Clean-Up – including removing temporary numbers from the new PBX and moving them back into XSTRA’s number pool
Port-Out Reject Codes
1 – Account number is missing or not valid
2 – ACN or equivalent is missing or not valid
3 – PAF has expired (Proof of Authorization Form. This is similar to CAF which is Customer Authorization form)
4 – Number has outstanding service orders
5 – Number Not Active or Suspended
