Maybe you’ve heard of a VoIP SIP Trunk or VoIP SIP Trunking. Maybe an acquaintance of yours saves money by using a Switch Telecom VoIP SIP trunk in his or her business. As a result, you’d like to know more. VoIP stands for Voice over Internet Protocol, or in more common terms telephone service over the Internet.
Because your business is already paying for the internet, you can now use our VoIP solution to make calls at a reduced cost.
A VoIP SIP trunk is the VoIP equivalent of the traditional analogue, basic or primary rate telephony service. It’s a multi-line service that you would use together with a Switch Telecom Hosted Switchboard or a VoIP PBX. You can also connect it to a traditional switchboard with a gateway device.
You can choose from a minimum of 4 up to 1000 channels. A channel is the number of concurrent lines you can have linked to a number or numbers to allow for concurrent calls both incoming and outgoing. This means that the trunk is ideal for both small and large companies, even call centres.
Direct Dial Numbers and a VoIP SIP Trunk
You can choose between a VoIP SIP trunk with just one number or one with multiple numbers. Multiple numbers linked to a trunk are called direct dial numbers.
Some of our clients give each employee a phone number that rings directly to their desktop or mobile phone. This allows callers to bypass the main business number. Some of our clients have more than one business number linked to their SIP trunk. We can provision 1 number up to a maximum of 10000 numbers on the trunk.
Moreover, you can upgrade the number of channels or add additional numbers to your SIP Trunk, at any time, without interruption to your business.

Switch Telecom offer both Pre-Paid (Advance) and Post-Paid (Arrears) payment options.
On Post-Paid billing the invoice is automatically generated and emailed on the 1st of each month in respect of that month’s service fee and the previous month’s calls.
Payment is collected strictly via debit order three working days later.
Subscribers who have elected to pay in advance will need to pay via EFT or by Credit Card on a strictly pre-paid basis. Airtime top-ups purchased using a Credit Card on the Switch Telecom Client Zone are immediate whereas EFT payments are subject to bank clearance delays.
You can take as many direct dial numbers as you require. We do however work on a 10 number to 1 channel ratio. For example, if you have a 4 channel trunk, you can have a maximum of 40 direct dial numbers. If you require more than 40 numbers the channels on your trunk will have to increase accordingly.
