In an MX-ONE system with several Media Gateways with local MX-ONE Service Nodes, it is necessary to set up RTP resources for inter-Media gateway communication to be able to make calls between the Media Gateways without using IP trunks.
The rtp_resource handling commands can be used for viewing RTP resources for an MX-ONE. For more information, see TECHNICAL REFERENCE GUIDE, UNIX COMMANDS for details.
When connecting a TDM device to an IP device, the RTP resource will be booked in the same gateway where the TDM device is situated.
When connecting two IP devices with forced gateway, or of a auxiliary device towards a IP device, the order to try to book the RTP resources will be in the following order.
At multiple choices the load will be distributed equally.
