OfficeServ 7100 SPECIAL APPLICATIONS
TECHNICAL MANUAL PART 2 JANUARY 2009
SIP Trunking Gateway
The MGI card(s) when used as a SIP (Session Initiation Protocol) trunking gateway
allows VoIP call connectivity to opposite MGI's, or other SIP standards based VoIP
gateways or devices. Calls placed in this mode are treated like IP tie line trunk calls. As
a tie line type trunk, incoming digits are expected. Programming allows routing of
incoming calls based on incoming digits, digit translation or trunk ring destinations.
Outgoing calls are made by selecting the trunk or trunk group and dialing the
appropriate digits to reach a predetermined destination. The flexible programming
allows outgoing digit manipulation with LCR like routing.
SIP trunking gateway programming follows the same programming as the H.323
programming but has an additional MMC to address the SIP attributes. MMC 837: SIP
Options, includes general SIP inquiries, response times, UDP ports, SIP server
addresses and other related SIP options.
ITP Keyphone Support
The ITP keyphones use the CODEC's on the MGI when calling a circuit switched digital
keyphone or an outside trunk in the OfficeServ 7100 system. The MP10/MP10a controls
the setup messages and determines if the destination (IE iDCS keyphones or outside
trunks) require the use of the MGI. The ITP keyphones only use the MGI when
accessing the OfficeServ 7100 circuit switched system side. ITP to ITP calls do not use
the MGI when called on a private network. This aspect of use can determine how many
MGI cards need to be installed based on ITP station traffic considerations. The number
of ITP keyphones does not need to match the number of MGI channels unless a
complete non-blocking application is required.
VoIP Networking (SPNet)
The MGI supports the voice when connections between OfficeServ systems are set up
to use the IP Networking Feature. IP Networking Features are the same as the PRI
Networking features but use IP as the transport method. Point to point calls are
originated and terminated as VoIP trunks but the informational data is exchanged via IP
packets between MP10/MP10a cards.
Facsimile over IP
This option assigns the number of ports used to support IP facsimiles. The MGI card
supports the T.38 facsimile over IP standard.
Each MGI-16 can support a maximum of 2 simultaneous fax calls. The same applies to
the on-board MGI.
