Frequently asked questions

What is required from me to port a number to VoIPline?

Everything is quite simple. All you need is to submit an application in customer portal: fill data in fields, e.g. name of the former provider (losing carrier), your account number there and which numbers you want to port to VoIPline. Also, you will need to attach a recent invoice from the losing carrier in any convenient format: image or PDF — it will prove that you actually possess a number(s). That's all, the rest of the work will be done by our porting team.
How long does it take to port a number(s) to VoIPline?

Our porting team works every business day and operates all porting applications they get on the same day but there are some factors that affect the porting speed.

First, it's required to get a response from the losing carrier: the faster he responds, the faster the porting will be. Also, it depends on the type of the number: geographic, toll-free or mobile — toll-free and mobile are much faster than geographic numbers due to peculiarity of telecommunication systems.

Overall, average porting time for toll-free and mobile numbers is up to 3 business days, up to two weeks for a single geographic number and up to 4 weeks for a number range.
Is there any outage for the number work during the porting?

No, there's no outage during the porting process. Before the actual port of the number to VoIPline Telecom the number will continue to work with the previous provider. The cutover day usually happens at night to minimise the chance of any disconnections: you wake up and the number already works with a VoIPline Telecom.

Also, we allow you to add the porting number to your call flow before the cutover day. Configure it for required users, queues, call recordings and so on. Once the porting happens, the number will start working the way you configured it before — it's very convenient.
Why a rejection can happen?

A porting rejection most often happens because of inattention. It is very important to provide all details correctly, without typos and so on. When we will pass the porting information to the losing carrier, he can reject it because of the typo in the account number or phone number. Even though our porting team checks the provided invoice with the data in the application, it's still recommended to double check all details before submissions. This way you can not only reduce time porting but also save money.
