ROUTING:

The IMG 1004 supports up to 66 total Route/Cause Code/Service Routing Tables per EMS. Each table can support up to 5000 entries. The IMG 1004 has a max capacity of 100,000 entries, or 20 tables each with 5000 entries.

Calls can be routed using the following criteria

• ANI (Calling Party)

• DNIS (Called Party)

• Incoming Channel Group

• Q.931 Nature Of Address (NOA)

• Time of Day

• Day of Week

• Day of Year

• Pre- and post-routing digit translations

• Multiple routing algorithms per trunk group or groups of trunks for IP to TDM and IP to IP with a- law and µ-law conversions

• Route to Treatment (Pre-call announcements or branding)

• Pre-call announcement (Branding)

For more information, click on the Overview of Routing link

MEDIA PROCESSING:

• (1) On-board DSP chip used for announcements and tones across IP and TDM networks.

• Each DSP chip can handle 128 Treatments. Max amount of simultaneous treatments is 128.

• The treatments are mapped in the release cause code table.
   

INTERWORKING:

The IMG 1004 supports interworking between SIP/H.323/SS7/ISDN.
