Gamma SIP Trunks

SIP Trunking has become a mature service trusted by numerous UK organisations, underscoring its reliability. To ensure a smooth transition, SIP Trunking can seamlessly integrate with existing ISDN connections.

With our national network ownership, we swiftly identify and address issues using advanced monitoring tools. This capability has helped us win many major UK Fixed Line Network awards in recent years, reinforcing the confidence of businesses choosing Gamma SIP Trunks.

While both technologies enable voice calls over the internet, SIP Trunking and VoIP differ in their capabilities. VoIP systems transmit voice calls over broadband connections, while SIP Trunking can handle various types of media, including voice, text, and audio. This means SIP Trunking can support multiple VoIP streams simultaneously.

Absolutely! Gamma SIP includes robust protection against phone hacking and misuse. As the incidence of telephony abuse rises, safeguarding your business from unauthorised call usage is crucial. Our CallGuard service ensures:

• Protection against unusual call activity
• Cost-effective solution for peace of mind

With Gamma as your SIP Trunk provider, you can expect top-tier call quality, reliability, and resilience right from the start. As the UK’s leading SIP Trunk provider, we prioritise quality of service across our network, ensuring exceptional performance. Our network supports both G.729 and G.711 codecs, offering flexibility and reliability for your business communication needs.

Technically speaking, there is no maximum number of channels that can be assigned to a SIP Trunk, which means your service will be able to handle a limitless amount of calls. However, each channel will require a certain amount of bandwidth, depending on the type and size of the data that is being sent and received across the network. This will need to be considered when planning and implementing your SIP Trunking solution.

With SIP Trunking, you can retain your existing number even when relocating, maintaining the perception of a local presence. We seamlessly transfer your old or existing numbers to avoid costly call forwarding charges. Enjoy CLI flexibility to display preferred numbers on a call-by-call basis, ideal for contact centres.

Of course! SIP Trunks offer flexibility for businesses with changing voice capacity needs. Whether you need to quickly scale up for sales campaigns or streamline operations across multiple sites, Gamma SIP Trunks allow you to adjust your connectivity easily. By consolidating telephony traffic into a centralised PBX, you can reduce maintenance costs and simplify management, even at remote sites where only an internet connection and handsets are needed.

Prices will vary depending on your channel capabilities and individual call charges (which are often calculated on a pence per minute basis). You can expect to pay between £50 and £150 for the monthly service rental, and between £3 and £150 per SIP channel. You will also need to consider the cost of connecting your phone system to SIP Trunk services; installation fees typically start from around £300. Number porting facilities will also incur additional cost.

Inbound call management can cater for business continuity in the event of a disaster or any other unforeseen event by instantly redirecting calls to another site. Changing to alternative locations guarantees a continuity of services without any kind of major disruption.

Inbound call routing services can manage what happens to calls when locations are busy or closed. Calls can be diverted to another location, including mobile devices, and can even be recorded for compliance or training purposes.

This helps to guarantee improved customer service, both now and in the long-term.

Call plans can be built according to operating hours, and modified instantly with any changing business needs. Inbound call routing can be scheduled according to business hours and call handling preferences.
