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.

  • RFC 3666 Call Flows - SIP to PSTN Dialing

  • ISDN to SIP UUI Support

  • SPIROU support in SIP INFO

  • Digit mapping in CAS
     

CUSTOMIZABLE VARIANTS:

  • Sangoma can rapidly customize IP and TDM variants for you using our patented PPL (Programmable Protocol Language) tool.
     

OAM&P:

USER MANAGEMENT:

  • Network Administrator can manage User Passwords and Privileges with the AdminView utility.
     

RADIUS:

  • The IMG 1004 uses Remote Authentication Dial In User Service (RADIUS) protocol for streaming the Call Detail Records (CDR)The implementation is compliant with RFC 2865 and RFC 2866. The RADIUS messages are sent to external RADIUS servers.
     

POWER REQUIREMENTS:

  • 100-240V AC 50/60 Hz with voltage range (90V to 240VAC)* Power consumption: 25  Watts
     

PHYSICAL SPECIFICATIONS:

  • Height = 1.72" (43.7 mm)

  • Width = 17.25" (438.2mm)
