How do UK SIP Trunks work?

  • UK SIP trunking uses VoIP to allow a PBX to connect to external telephone networks via the Internet.
  • The Internet acts like a traditional telephone line, so a user can communicate with telephone subscribers that use a fixed or mobile telephone service. AstraQom uses the SIP trunks to deliver the communications from your PBX to the outside networks, and from outside networks to your PBX.
  • SIP trunks can offer significant cost savings for enterprises, because they eliminate the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces).
  • Business that have invested in an internal IT infrastructure are great candidates for a SIP trunk because they can easily plug it into their SIP environment – there is no upside to hanging on to existing landlines when there are tools in place for a more easily-managed, lower-cost communications solution from AstraQom that is versatile and equally reliable.
  • As UK SIP Trunking providers, we are able to enhance the capabilities of your software or device by providing a complete solution for all internal and external communications. Whether you have a traditional PBX or Virtual PBX, a calling card service or a call center solution, we can help you make the most of your IP investment with a SIP Trunk, which is a combined solution of DID Numbers and bi-directional channels scaled perfectly for your needs.
  • Usually, the the most important aspect of deploying a SIP Trunk is the channel and DID distribution. SIP services from AstraQom UK let you combine these two elements according to your business needs, making it probably the most versatile and scalable solution available on the market.

UK SIP Trunks Features and Capabilities


Aggregated SIP Trunk

Eliminate the need for dedicated trunks by allocating a number of channels that will be distributed dynamically wherever you need more capacity. For example, if you have 5 DID Numbers and 10 channels and 3 calls are coming to one of your numbers, 3 of your channels will be allocated to allow the connection to that number, leaving the other 7 channels available for further incoming or outgoing calls on your other numbers.


Bi-directional SIP Trunk

AstraQom UK offers both inbound and outbound channels capability in our SIP trunks.


Call termination

The service offers national and international termination using AstraQom network. You are free to choose to be limited to a specific geographical coverage or get something customized just for you.
