This section describes how to add a PBX to an ICE Telephony Gateway. For instructions on configuring a Telephony Gateway see Appendix J: ICE Gateway Deployment > Running an ICE Telephony Gateway. This option provides private call connections between ICE users on ICE Desktop or Mobile, but does not provide a PTSN connection. For that you must deploy a SIP PBX.

Use the instructions in this section to add a SIP PBX to your ICE System for external call connectivity.
