The Orbtalk business SIP Trunk service is built on Orbtalk's robust VoIP platform. Orbtalk SIP Trunking will allow your organisation to retain the advantages of their existing telecoms equipment, whilst gaining the additional functionality and benefits of IP Telephony. Companies can retain their existing handsets and have the flexibility to add remote or central IP users when needed - all of Orbtalk's SIP Trunks are routed with Tier 1 carriers giving you ISDN grade call quality. Orbtalk now offer online SIP trunk signup for fast provision and speedy deployment.

The Orbtalk SIP trunks support a wide range of hardware PBX's and IP handsets. For a list of supported SIP devices please see our Compatible Devices.

Business 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 SIP Trunking instead of using costly traditional phone lines. At this point, the IP call can be routed using the Customer's current data provider. Alternatively, Orbtalk can assist with the migration or supply of data connectivity including ASDL, SDSL and leased lines and can provide a wide range of UK geographic and International numbering services including number porting from BT to IP.

This solution offers 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 maximise existing infrastructure and reduce call costs.
