SIP Trunking


Your key to agile, scalable cost-effective communications

SIP Trunking replaces the traditional telephone lines that connect your communications infrastructure to the PSTN with virtual lines that carry voice over an Internet connection. SIP Trunking gives you greater flexibility in terms of volume and geographic distribution, and it is a highly scalable solution. If you need more capacity, you can simply activate more channels without having to install more lines.

SIP Trunking solutions also reduce costs. SIP channels cost an average of 40% less than traditional ISDN lines. Voice calls on SIP trunks can be carried over the same network as data traffic. With just one network to manage for voice and data, you’ll save on support costs. With GoCo SIP Trunking, there is no compromise on quality or reliability. The solution is capable of supporting crystal-clear HD voice and, as a digital solution, SIP reliability is higher than legacy cabling.

GoCo SIP Trunking – your questions answered

  • What is SIP Trunking?

    An SIP Trunk is a digital circuit using Internet and IP networks to carry voice calls from the PSTN to a PBX. SIP Trunks replace traditional analogue circuits and can reduce your overall IT management and administration costs by simplifying networking.

  • How many SIP Trunks will we need?

    You should initially purchase SIP Trunks based on the number of simultaneous calls you anticipate needing. However, you can increase or reduce the number on demand if your requirements change.

  • Will we need to increase our bandwidth?

    You may need to increase your bandwidth if you carry a lot of data traffic as well as a high volume of voice calls.

  • What happens if our Internet connection fails?

    If your Internet connection fails, your SIP Trunk will be unable to process inbound or outbound calls. However, incoming calls can be redirected over a back-up circuit to other working numbers, mobile phones or voicemails and processed later so you won’t lose any calls.

  • Do we need additional equipment to use SIP Trunking?

    GoCo’s SIP Trunks work with your existing IP-PBX. Our solution is compatible with more than 30 IP PBX models. SIP Trunks can also be used with analogue devices via an Integrated Access Device. 

  • Do we need SIP Trunks if we have a hosted solution? 

    No. SIP Trunking is designed for use with premise-based infrastructure such as an IP-PBX or analogue device. 

  • Why is SIP Trunking more scalable than analogue circuits? 

    Traditional analogue circuits can only support a fixed number of communication channels, which limits your possibilities when trying to scale to the exact number of lines you require. With SIP Trunking, you can add or reduce capacity by one circuit at a time to meet your exact needs. You may need to scale the bandwidth of your Internet connection to align with the new number of lines.
