How do I connect a SIP trunk?
SIP trunks are provided by Telephonic: a licensed ComReg Internet Telephony Service Provider. Unlike in traditional telephone lines and trunks, where bundles of physical wires are delivered from the tradition telephone company to your location of business, a SIP trunk allows your organization to replace these traditional fixed PSTN lines with PSTN connectivity via a single digital connection to Telephonic over the Internet.
A SIP trunk account normally consists of a username and password which allows your IP-PBX to connect to the Telephone network. Once you IP-PBX is successfully logged-in to our gateways, we will automatically be able to send inbound calls to you.
What if our PBX is an older model?
In most cases your PBX will be an IP-based PBX which also connects to all of your extensions and telephones using IP. However, you may also access Telephonic's SIP trunk service using traditional digital or analog PBX using a simple SIP adapter gateway.
