SIP Trunking Configuration Guides
The following Configuration Guides are intended to help you connect your SIP Infrastructure (IP-PBX, SBC, etc) to a Telnyx Elastic SIP Trunk.
Be aware, due to the large number of versions, variations, add-ons, and options for many of these systems, the settings you see may differ from those shown in our Configuration Guides. As such, these documents are intended as general guidelines, rather than configuration templates. There is an assumption of familiarity with your network and SIP infrastructure, and how they work.
Guide Listing
Telnyx cannot provide direct support for third-party products; you should contact the manufacturer for your PBX/SBC for assistance in configuring such products.
