Moving phone numbers is the one change where every user notices a mistake straight away. A short checklist takes most of the stress out of it.
Before the porting date
- Confirm the full list of numbers with the customer, including fax and alarm lines.
- Set up the trunk in advance and test outbound calls with a temporary number.
- Build the inbound rules for every number, even though nothing arrives on them yet.
- Agree on who calls whom if something goes wrong.
On the day
- Call each main number from a mobile phone and from a landline.
- Check the caller ID that is shown on outbound calls.
- Test the paths outside office hours: voicemail, holiday schedule, queues.
Afterwards
Keep an eye on the event log for the first few days and ask the customer about missed calls. Problems with a single number often show up only when that number is first used.
