SIP trunks provide you with an IP alternative to traditional PSTN delivered over IP Connect and can reduce your costs by:

  • removing expensive interfaces to the PSTN
  • reducing the number of trunks needed by up to 30 per cent
  • giving you low cost international PSTN minutes
  • self-service administration and reporting giving you control and flexibility over your communications
  • centralised SIP – no need to segregate (logically partition) SIP traffic per country
  • fully compliant with in-country regulation, supports multiple codecs.

Our One Voice platform offers SIP services in 73 countries, with full PSTN replacement in 21. We support 350+ customers, with over 380,000 channels.
