SIP is a signalling communications protocol similar to that used by ISDN lines. SIP Trunks from Intratel empower our clients to use their existing IP PBX phone system on our SIP network.
Intratel SIP Trunks gives a business-class voice service harnessing the full potential of high quality broadband links to make significant savings in overall communications costs by eliminating expensive PRI, FRA and ISDN monthly line rental charges.
