Configure an Acme Packet SBC with Telnyx
Acme Packet produces and markets session border controllers (SBCs) to protect SIP-based VoIP networks.
This guide will go through specific configuration for use with your Telnyx Trunk. A good place to start is by reading the entire ACME SBC guide for details of the full setup.
For step by step instructions on each of the requirements on the Telnyx Mission Control Portal, please follow this guide.
Once your portal is up and running, you can start configuring your ACME Packet E-SBC.
You are now all set on the Mission Control Portal side and are ready to configure your Telnyx trunk within your ACME SBC system.

Telnyx accepts the called number on outbound calls in 10 digit, 11 digit and +11 digit format, so there is no need to modify rules for the called number.
However, we have a caller ID policy and require the calling number to be in +E.164 number format.
The example below helps append a +1 for US calling numbers. This is the session translation rule on the calling number.
session-translation id includeCallingPlus rules-calling includePlus rules-called
Then define the rule to append +1 to the calling number:
translation-rules id includePlus type add add-string +1 add-index 0 delete-string delete-index 0
Then apply the translation rule to take effect on the outside realm:
realm-config identifier OUTSIDE ... in-translationid out-translationid includeCallingPlus ...
In the example below, the SBC will change the codec list for all clients that make outbound calls through the SBC's realm, such that PCMU will be preferred codec offered.
realm-config identifier clients ... options preferred-codec=PCMU ...
