SIP Trunking is an IP alternative to ISDN that offers flexible numbering, can be easily scaled up or down and can be provisioned in hours.

The service is available via DSL or Ethernet connection and is designed to work successfully with all the leading IP PBX brands in the UK market giving you peace of mind in knowing that your PBX hardware works with the network service. Compared to ISDN SIP Trunking is cheaper on a per channel basis, more flexible in terms of what telephone numbers you can have and where you can have them, is quicker to install and offers a very robust business continuity service that ensures your business never loses calls. Eze Talk’s SIP Trunking can support connections ranging from two channels for businesses with small PBX’s to no limit on the number of channels that can be supported for large enterprises and contact centres.
