Miscellaneous
• The MIPU / LIPU / GIPH supports both G.711 and G.729A standard codec compressions
simultaneously. The type of compression used is set independently for each telephone in
system programming.
• With the MIPU / LIPU/ GIPH, the IP telephone works with DSL and cable routers.
The MIPU / LIPU / GIPH operates on the network at 100 Mbps and can be connected to a fast
switch router, LAN, WAN, etc. When connecting remote IP telephones to the MIPU / LIPU /
LIPS and GIPH over the Internet, a VPN router is needed to circumvent Network Address
Translation (NAT) and firewall issues by tunneling.
• MIPU / LIPU / GIPH provides MEGACO+ mobility to enable roaming. The LIPU / LIPS and
GIPH enables remote IP telephones to be connected over VPN and non-VPN IP networks.
• MIPU / LIPU / GIPH firmware can be updated locally or remotely using eManager. This
enables service personnel to update IP equipment with new features and enhancements as they
become available. Updates require a brief interruption of IP telephone operation (a few
minutes).
