About H.323 gatekeepers and SIP proxies

You can configure the Pexip Infinity platform with the addresses of one or more H.323 gatekeepers and SIP proxies. These are the call control systems that can be used to route outbound H.323 and SIP calls on behalf of Pexip Infinity.

Each System location can have a nominated H.323 gatekeeper and/or a SIP proxy — these are used to route outbound H.323 and SIP calls from that location.

Each Call Routing Rule can also have a nominated H.323 gatekeeper and/or a SIP proxy — these are used to route outbound calls for rules that are targeted at external H.323 and SIP systems.

The H.323 gatekeepers and SIP proxies configured here are used for outbound calls from Pexip Infinity. They do not determine the systems used to route inbound calls to Pexip Infinity. Pexip Infinity will not automatically register with any systems configured here. To route inbound calls from a gatekeeper or SIP proxy, you must configure these systems with neighbor zones that direct calls to Pexip Infinity. For more information see Call control.

Outbound calls are made from Pexip Infinity when:

When a Pexip Infinity Connect user who is connected to a particular Conferencing Node adds another participant, the call will be routed to the H.323 gatekeeper or SIP proxy associated with the system location to which that Conferencing Node belongs. If you do not specify an H.323 gatekeeper or SIP proxy for a system location, Pexip Infinity Connect users connected to Conferencing Nodes in that location may still be able to dial in other participants. To enable this, the user must enter an IP address or FQDN (and for the latter, DNS must be configured properly), thus allowing Pexip Infinity to dial the participant directly.

To add, edit or delete an H.323 gatekeeper, go to Call control > H.323 gatekeepers.

To add, edit or delete a SIP proxy, go to Call control > SIP proxies.

After adding the details of the H.323 gatekeeper or SIP proxy, you must then add it to the relevant location (Platform configuration > Locations) or Call Routing Rule (Service configuration > Call routing).
