User's Manual
Figure 29-2: Defining SAS Proxy Server
The VoIP CPEs (such as IP phones or residential gateways) need to be
defined so that their proxy and registrar destination addresses and ports are
the same as that configured for the device's SAS IP address and SAS local
SIP port. In some cases, on the UAs, it is also required to define SAS as their
outbound proxy, meaning that messages sent by the UAs include the host
part of the external proxy, but are sent (on Layer 3/4) to the IP address / UDP
port of SAS.
