For businesses who have already invested in their onsite PBX, would prefer to keep their PBX management internal, or are not yet prepared to make the jump to cloud based telephony, SIP trunking provides the best available upgrade to a traditional telephony system. Furthermore, BT will stop selling ISDN in 2020 and will stop supporting the service by 2023; so now is the time to prioritise the migration to SIP.
Adam Phones leverage the largest proactively monitored SIP Trunking network in the UK to deliver and support our business grade SIP solution. Voice and data are provided over the same connection, maximising network efficiency and enabling companies to migrate away from legacy ISDN and costly maintenance.
Our services are compatible with all leading PBXs, feature a business grade Quality of Service, and are proactively monitored to prevent downtime. Additionally, because of the nature of SIP trunking, we can upscale or downscale our clients’ services almost instantly, and it is easy and efficient to load balance calls between multiple sites.
