Features
IP Telephony
The MIPU / LIPU / LIPS and GIPH supports all "IP" functionality in the Strata CIX. This includes
the following:
• Multiple protocols supported:
•
• SIP (Session Initiation Protocol) telephones provides basic functionality that can be used for
very basic user capabilities. Toshiba supports only the Uniden telephone that Toshiba has
approved for interoperability.
• SIP Trunking is an application layer protocol used for establishing sessions in an IP
network. SIP Trunking allows the CIX to get PRI like services from an Internet Telephony
Service Provider using SIP.
• MIPU / LIPU/LIPS and GIPH IP endpoint devices and interfaces (requires IP Endpoint
license):
• Toshiba IP telephones
• SoftIPT on PDA, Notebook and TabletPC's
• Wireless IP Telephone
• SIP IP telephones
• Strata Media Application Server (MAS)
• MIPU / LIPU/LIPS Port devices and interfaces (requires Basic Port license on all CIX systems,
except with GIPH because all Basic Ports are fully licensed on CIX40).
• IP Attendant Console
• MAS Voice Mail Ports
• MAS ACD Announcement Ports
• StrataNet IP Network resources
• In addition to the above features, the MIPU also includes the following:
• Backward compatibility with LIPU
• Compatible in the CIX40, CIX100, 200, and 670
The MIPU16 is compatible with the CIX40 with CIX Release 5.1 software.
• Log files collected remotely from the MIPU
• MIPU card uses one IP address
• Tail-length echo cancellation increased from 32 ms to 64 ms (G.711 and G.729A)
• Quality of Service (QoS) threshold alarm notification and measurement
• IP Mobility support
• Connects between a node using G.711 A-Law codecs and a node using G.711 Mu-Law
codecs.
• The maximum transmission interval of voice packet at using G.711 codec is 40ms (80ms in
LIPU)
• RTP ports used by IPTs can be user modified
• Continuous rebooting (even after six failed attempts)
• For a comparison of the MIPU and the LIPU refer to

MEGACO+ delivers a consistent user interface over all Toshiba IP endpoint devices,
except SIP telephones. Toshiba has enabled the MEGACO protocol for call control to
provide more stimulus/response capabilities that allows all the feature functionality of
digital desktop telephones to be supported on IP telephones. The MEGACO+ protocol is
able to implement this feature functionality consistency much better than could be done
using other VoIP protocols.
