SIP Trunking works in conjunction with VoIP by utilizing a SIP-based PBX to deliver telephone system services without a traditional analog phone line. Rather than a physical wire, a SIP Trunk acts as a ‘virtual’ line that uses a data circuit (Cable Modem, T1, Ethernet over Copper, DSL, etc.) to connect to an ITSP network. Frequently included in an SIP Trunk are voice, video, and streaming media services, making this option ideal for businesses.
Thanks to the lack of physical lines requiring maintenance with a SIP Trunk, costs are considerably lower than traditional business phone service. SIP Trunking coupled with VoIP can save a company up to fifty percent on their monthly bill. SIP Trunking permits companies to only pay for the numbers they use rather than getting stuck in an agreement that includes excess analog lines. With this method, companies are more efficient with the amount of resources they use.
Additional benefits of SIP Trunks include:
- Inexpensive DID – A Direct Inward Dialing number, the number clients will use to reach a business on, costs less when purchased with a SIP Trunk. In the past, a DID is obtained directly from the phone company and charges were applied for the DID, IT and maintenance services, as well as the hardware associated with the system. A DID with SIP Trunking doesn’t include this infrastructure.
- Better customer service– By adding additional geographical and international numbers, businesses allow customers more options when dialing in. With this barrier between a business and their customers lifted, sales will increase.
- Flexible locations – If a business changes office locations, they can still keep the same number because SIP Trunks are not bound to a physical location.
- Leverage a modern IP PBX– Modern IP PBX allows customers increased productivity, mobility and a boost in sales. Furthermore, connecting an IP PBX to SIP Trunks is much easier than via the PSTN.
- Flexibility– It is easy to add channels to your SIP trunk to cope with increased calls. A simple phone call will allow you to add channels, and often this can be done immediately.
- Troubleshooting – SIP Trunking with VoIP increases consistency of services by providing a level of redundancy. When system failures and emergencies occur, SIP Trunking providers can reroute services to a redundant data line or forward the PBX to mobile phones to keep your business up and running.
