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.
