Zone data is a tool employed to easily manage the characteristics of groups of devices under the control of an
MPB/UCP. Such devices can be grouped into a Zone to define common characteristics, including Country
Code, DSCP, RTP packet handling, etc. Common attributes are defined at the device, Zone, and Inter-zone
levels. Device settings have priority over system and Zone settings, while Zone settings have priority over
system settings.
Generally, the transport of RTP packets should be peer-to-peer communication over either a LAN or VPN. If
iPECS devices are separated by a NAPT server or direct peer-to-peer communications are not available,
packet relay must be employed to assure communication. In packet relay, RTP packets are received by a local
VoIP channel, which is under control of the MPB/UCP, and the IP address is translated from public to the
device’s private address. The VoIP channel implements a secure channel using IPSec protocol. Devices can
be assigned as part of an “RTP Relay group” to use the same VoIP channels to implement the relay of RTP
packets. Packet relay groups also provide for conversion of multi-cast packets from the MPB/UCP to uni-cast
and back again at the group level to multi-cast. Note packet relay requires a VoIP channel to be available
locally for each simultaneous call that requires packet relay.
4.4.13.2 Device Zone Number – PGM 436
Selecting the Device Zone Number returns the Zone Number data input page. Enter the Sequence number
range (refer to section 4.4.1.4System & Device IP Address Plan - PGM 102 & 103) and click [Load]to assign a
device's zone number. Click the [Save] button after changing Value.
Enter Device/GW sequence Range: eMG80/100: 1-300 / eMG800: 1-2890 / UCP: 1-3688
