SIP Trunking
01
SIP - Session Initiation Protocol
SIP (Session Initiation Protocol) is used to send voice calls over the internet via an IP telephone system rather than using traditional PSTN (analogue) and ISDN (digital) lines.
SIP Trunks are now the number one choice for voice communication where an onsite PBX solution is utilised. They are already used by thousands of businesses nationwide.
Why SIP Trunks?
SIP Trunks are a great solution in the event of a disaster recovery situation. They are also very cost-effective compared to traditional PSTN and ISDN services
Can I change my existing lines to SIP Trunks?
Yes you can. Most PSTN and ISDN numbers can be easily ported onto our SIP platform.
