The Cost-Effective And Flexible Alternative To ISDN
Flexibility with phone numbers
SIP trunking enables you to move office and keep the same geographic number without any ongoing call-forwarding costs or those associated with producing new company stationery.
If your office has to be temporarily relocated in an emergency, this can be achieved quickly and cost-effectively with SIP trunking to keep your business working.
For businesses with multiple sites, SIP trunking provides the opportunity for line rationalisation and reduces the number of PBXs you need to maintain – while retaining full control of the numbers associated with your business.
IP connectivity costs less than ISDN with lower call costs, free internal calls between extensions and offices and lower line rental costs for multi-sites. Also, no expensive call-forwarding costs are required should you relocate or need to divert calls in the event of a disaster.
SIP trunking provides a phone service that will cope with any situation and give you business-grade resilience for your telephony. Whether you need to keep your business running in a disaster or emergency, or you need to load balance your calls between sites during peak hours, SIP trunking delivers.
Compatible with Skype™ for Business
Gamma SIP Trunks are integration tested and approved to interoperate with Skype™ for Business, allowing you to directly connect to the platform to make external calls.
Who Is SIP Trunking Aimed At?
SIP Trunks are suitable for any size of business, from small businesses to large enterprises and government organisations that currently have a PBX, unified communications solution or a key system.
Our resilience design allows dual SIP endpoints to act as the active sites and offer stand-by resilience to the other. It is similar to Active Standby except that both sites are active and provide failover for the other.
