Smart SIP

Switch to SIP Trunks today and save!

With SIP Trunking, companies can connect their PBX system to a PSTN network via the Internet, instead of the bundles of physical wires used in traditional telephony. SIP trunks typically use the same Internet access that is used for transferring data, for simplified administration and troubleshooting.

In addition, SIP Trunking provides significant savings by eliminating the need to install local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces), or PRIs (Primary Rate Interfaces).

If your PBX is not IP-enabled, one will be installed on your premise to convert all calls from traditional phone service to less costly VoIP.
