74 Chapter 6 Setting up the private VoIP network
When you set the value of the RFC2833 Dynamic Payload field, if the value is greater than 0, then
this feature is enabled. If the feature is enabled then DTMF digits are sent in RTP packets. For
CS1000 Release 4.5 set the value to 0.
For detailed information on entering the values in this panel, see the Networking Configuration
Guide (NN40020-603).

Line pools

Both VoIP trunks and PSTN trunks must be configured in separate line pools. In the default state,
all VoIP trunks are assigned to line pool BlocA and all PSTN trunks are assigned to line pool A. It
is not necessary to reassign the line pools.
Instructions for configuring line pools is provided in the Networking Configuration Guide
(NN40020-603).

Call routing

Call routing is covered in depth in the Networking Configuration Guide. The instructions in the
SRG50 Configuration Guide are an abbreviation of that material, and only cover procedures that
are specific to SRG operations; that is, for calls from redirected IP telephones. For more detailed
information, see the Networking Configuration Guide.
Note: The DNs for the main office telephones system are marked off by the vacant
number routing feature. SRG does not support Vacant Number Routing (VNR).
Instead, SRG uses Call Forward All Calls to emulate VNR for the SRG IP telephones that
are in normal mode. When the telephones switch to local mode, Call Forward All Calls is
cancelled for those telephones.
A single destination code and route (or a group of destination codes and routes) can be set
up on the SRG to route all the calls that are not terminated locally by the SRG. These calls
are routed over the VOIP trunks. In the case where the VoIP trunks become unavailable, the
calls can be routed to the proper location using PSTN fallback. This is similar to the VNR
feature in CS 1000.
