Here are some Frequently Asked Questions about SIP Trunks.
SIP is the abbreviation for Session Initiation Protocol. SIP trunking enables phone system operation over the internet, replacing traditional phone lines, and allows voice calls between parties using your phone system.
SIP trunking is a method that is used for sending voice and other communications services over the internet. It works in conjunction with a PBX (Private Branch eXchange) which is IP-enabled.
A SIP Trunk is basically a group of the SIP channels. Each SIP channel can handle only one call. This functionality is very similar to a traditional analog telephone line. Number of trunks depend on how many simultaneous calls you require.
Since the number of channels on a SIP trunk changes as you connect and disconnect calls, it involves no particular number of channels. For example, if there are 20 calls on-going, the SIP trunk will have 20 channels for these calls.
SIP is a protocol for managing real-time multimedia, while VoIP relies on SIP for call routing. Business VoIP is a complete phone system that uses SIP for expanded telecom functionality. SIP trunking is scalable and can be used with an IP PBX.
You only need one SIP trunk to handle all of your business communications. You can adjust your concurrent call capacity by adding or removing channels or opting for pay-per-minute billing for unlimited inbound calls.
You need access to manage your PBX and the credentials from your SIP trunking provider to use SIP trunking. Nextiva offers free assistance for setup and is compatible with most IP PBX systems. Additional features like DIDs, toll-free numbers, and call paths can be added by requesting a personalised quote.
SIP trunking is cost-effective compared to traditional business phone systems. Wavetel Business offers pay-as-you-go pricing with automatic volume discounts as you scale. For a detailed pricing breakdown or a custom quote, speak with one of our experts.
