What is SIP Trunking?
Session Initiation Protocol (SIP) allow businesses to retain the advantages of their existing telecoms equipment, whilst gaining the additional functionality and benefits of IP Telephony. Companies can retain their existing telephone system and have the flexibility to add remote or central IP users when needed - all routed with Tier 1 carriers.
SIP Trunks can be linked to a customer's current PBX using an IP enabled PBX or by using a Media Gateway. Outgoing calls are then routed through the PBX and out via the SIP Trunk instead of using costly traditional phone lines. At this point, the IP call can be routed using the Customers current data provider. Alternatively, NGC can assist with the migration or supply of data connectivity including ASDL, SDSL and leased lines and can provide a wide range of UK and International numbering services including number porting from BT to IP.
SIP Trunks offer a future-proofed and innovative service to customers who do not wish to replace their existing telecoms equipment. Customers also benefit from the ability to take advantage of IP Telephony features when right for them, whilst also continuing to 'sweat' assets and reduce call costs.
