Advanced Configuration Settings
The advanced feature settings below only apply to deployments with All Ring Groups or SLA/SCA (Shared Line Appearance or Shared Call Appearance) configured. These configurations require the greatest number of SIP transaction resources and should be as close to accurate as possible. If these Advanced Configuration settings don’t apply to your Hosted VoIP deployment, fields should be left at default “0”.
All-Ring or SLA/SCA Groups
In most cases, when deploying an “All Ring” Group (meaning a single number rings multiple phones simultaneously), or SLA/SCA (a single line configured on multiple phones that rings simultaneously), you will often have multiple groups of phones. If multiple groups are required in your application, you’ll need to define each group separately. (Note: This tool will allow you to enter up to 5 separate groups, (Group 1 - Group 5).
Number of Phones in All Ring or SLA Group
This is where you will define the number of phones assigned to a single number ring group, or the number of phones configured with Shared Line Appearances/Shared Call Appearances. (Note: Think of SLA/SCA as the old Key System (Square Key) mode of operation, in which users have the same incoming/outgoing line appearances configured on multiple phones, (e.g. Line 1, Line2. Line 3, etc.)
Number of Phones w/Full Mesh BLF Configured
Only applies to phones within this group that have BLF (Busy Lamp Field) buttons of other group members configured on their phones. If NO BLF is configured within this group, leave this field as “0”.
Simultaneous Inbound Calls to Group
Please estimate the number of “simultaneous” inbound calls to this group. This applies to both Ring Group & SLA groups, with the minimum number being “1”. (Note: Simultaneous calls entered here are subtracted from the "Total Number of Phones in use" in the final calculation.
Required number of SIP Transaction Resources
This field provides you the total number of SIP Transaction resources required for your configuration. With this number, you can then go to the AOS Feature Matrix to locate a Product that exceeds the SIP Transaction Resources calculated in this field.
