[2022-06-25] As we consolidated all tech blogs into Dewapost website, we also post this blog into Dewapost.com and we reformat the content to suit within their guideline.
What involved
The site relocation process is involving the new carrier, losing carrier, PBX maintainer, system integrator and internal IT staff.
What we found
Communicating regularly with the carrier is a key, especially for the Account Manager, Project Manager, and Delivery Specialist about the site and ensuring the site is a relocation not changing service. There was the case that the carrier assumed that the site is changing service NOT relocation.
Porting number process involving losing carriers takes about 10 working days for registration. Then another 10 working days for booking the actual porting. The registration has an expiry which is 90 days. It has 3 chances to do the porting. It may have costs involved associated with cancelling and reissuing the porting.
For the booking porting time, it has a morning, afternoon or evening time slot. Friday evening and Monday morning have high demand. Always do the booking early as possible in order to meet the right time slot.
When do the booking for the porting, it's better off not to aim for 10 working days dot and allow couple more days extra (ie. 12 working days in total) just in case the Porting Manager is not available on the day or to have more chance for the preferred time slot.
When the service number has an in-dial range (100 block numbers), the redirection can't be done for all numbers. Normally, the main number and fax numbers are nominated as a redirection instead.
Some carriers have a lead time for modifying configuration on routers potentially 5 - 10 working days. It has a form that needs to submit. Some carriers have no lead time at all - changing can be done instantly via phone.
In some cases, the data line might not come in on time. Plan to have the 3G/4G solution as an in-term solution. This device is a modem/router with Wifi support.
We have a replacement of the Account Manager due the current one is away. We have to deal with third-party for hardware procurement, and ensure to communicate about the tech fund to the new account manager.
When organising the cut-over for data and voice lines, ensure to have an hour apart. For instance, the phone is 9 am and the data is 10 am. Otherwise from a technical point of view, it requires dealing with receiving a call from the carrier for testing.
