SIP Trunking
What is it?
The term SIP Trunking comes from the old days of wired telephony when calls went over the public switched telephone network (PSTN). Today, SIP Trunking offers businesses the ability for savings on line rental and cheaper telephone calls.
A SIP trunk sets up communication between an enterprise PBX and an Internet Telephony Service Provider (ITSP) and the trunk includes as many multiple voice sessions as a business needs.
SIP trunks provide immediate cost savings and eliminate the need to purchase expensive BRIs, PRIs or PSTN gateways, as well as providing back up, resilience and DR solutions in the event of failure.
Your business will require an IPBX or legacy system with Media Gateway Interface, sufficient IP bandwidth to support the required channels (ADSL, SDSL or leased line), and a service provider that supports SIP trunking.
SIP trunks provide excellent voice quality and, as a number of failover solutions can be implemented, is more reliable than a traditional PSTN.
