SIP trunking

Frequently asked questions

  • What is the difference between SIP trunking and hosted PBX?

    It’s not about the difference between them but how these two services cooperate with each other. SIP trunking is a service that allows you to connect your VoIP compatible onsite phone system to the cloud to have a connectivity with the outside world. Hosted PBX is already a telephony system that operates via the Internet but you can interconnect them to use some of the hosted PBX features with SIP trunking, e.g. provide an inbound toll-free number or record calls.

  • What are the benefits of SIP trunking compared to PSTN and ISDN?

    SIP trunkng replaces older PSTN and ISDN phone lines and uses the Internet to transmit voice data. Key benefits of SIP Trunking are:
    - Lower cost compared to older PSTN and ISDN connections;
    - Ability to easily scale up or down with the number of channels or simultaneous calls required;
    - It is also easy to relocate as you could use your SIP Trunk anywhere you can get access to the Internet;
    - SIP Trunk can be configured to encrypt all voice data before transmission and allow for HD voice codes with significantly better voice quality to be enabled.

  • What are SIP trunk channels?

    A SIP channel is used for one incoming or outgoing call. You can think about it as a sort of a standard phone line. Every SIP trunk can support multiple SIP channels.

  • How many channels can a SIP trunk handle?

    Number of channels supported by SIP Trunk is limited by your Internet connection speed, but most of the modern broadband connections are capable of supporting dozens of channels. E.g. 10 Mbps connection could support about 100 simultaneous calls.

  • How fast Internet connection is needed for a good SIP trunking operation?

    This depends on your onsite PBX and its supported codecs. If your PBX supports G.729, you only require 0.03 Mbps including overheads. Therefore, if you have a reliable connection of even 8 Mbps, you could have about 260 simultaneous calls connected. However, quality of calls will highly depend on the reliability of your internet connection, so it does not have to be very fast but it must be reliable and stable.

  • What happens if my Internet goes down?

    Even if your Internet connection goes down, you'll still continue to receive inbound calls. This is possible thanks to diversion of calls to mobile phones. How it works: commonly a call is coming to the inbound number and then passes to SIP trunking. In case there’s no connection with the SIP device due to lack of internet connection, a call will transfer to mobile phone or any other phone number you will configure.

  • Why is there a minimum monthly spend?

    We offer lower rates for larger call volume accounts. For services with minimum monthly spend we deduct the minimum monthly spend amount on the 1st of each month and this amount becomes call credit on your account. There are no extra charges for calls up to the minimum monthly spend, calls over are charged at the call plan rates.

Rejection fees $10.00 p/number

Non-GEO number porting (any carrier)

Porting from any carrier$22.00 p/number
Resubmission fees:
Rejection fees $22.00 p/number
Note: You can bring your current local or non-geographical number to VoIPLine. You should be aware that when a number is ported any associated service(s) with the number could be disconnected. We recommend you check with your current service provider if you are unsure of the effect porting will have on any service(s) you still need. Once the porting is complete, we recommend you get in touch with your previous service provider to ensure that you will no longer be billed for any of the services that you previously used.
If you have any linked numbers associated with the number you wish to port then please contact your current provider and inquire about the detachment of those from your number or a cancellation. You can however also port the additional lines over to us if that is necessary. Please note that the porting process will be rejected if you try to port a number that is still linked to another number that is not being ported, which will also cause delays.
If incorrect information is supplied on the porting application and your porting is rejected, resubmission fees will apply.

Number porting

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.

Call recording storage

Convenient cloud storage of call recordings

Call recording storage can be configured individually for each 'User' object in the PBX, as well as for each 'Call recording' and 'Conference' objects. For users, you can set whether all incoming or outgoing calls will be recorded, or only those when the user himself or herself wants to record a call or part of a call.

Call recordings can be conveniently searched by a variety of parameters: type of object or call, who or where the call was made, and in what time period. The recordings can be listened to or downloaded immediately. Among other things, if the user has the Webphone set up, he or she can listen to their own call recordings from the call history.

The pricing for cloud storage is configurable and can be changed at any time, and to avoid overpaying, you can set up automatic deletion of old recordings. In addition to cloud storage, you can also receive call recordings to email absolutely free of charge.
