Resonance Telcom SIP trunks for Asterisk
Point your Asterisk server at Resonance Telcom SIP trunks and keep the dialplan you have already built.

About Asterisk
Asterisk is an open-source telephony framework sponsored by Sangoma. It is the engine behind many commercial and do-it-yourself phone systems, and it can be configured through text files or a graphical front end.
Asterisk speaks SIP natively, so connecting it to Resonance Telcom is a matter of defining a trunk endpoint and routing calls to it in your dialplan.
Why Resonance Telcom for Asterisk
- Standard SIP trunk settings that drop into your existing PJSIP configuration.
- Your dialplan, IVRs and queues stay exactly as they are.
- Engineers who can read an Asterisk log and help you troubleshoot quickly.

Asterisk FAQs
Which SIP channel driver should I use?
Use chan_pjsip. The older chan_sip driver is deprecated and has been removed from recent Asterisk releases.
Can I use registration or IP authentication?
Both approaches can work with Asterisk. Which one your trunk uses is confirmed when your account is set up.
