SIP Addresses

In this group of parameters, the IP addresses or host names for the SIP server, the SIP regis-
trar, and the SIP gateway are defined.
SIP server address provides the IP address or host name of the SIP proxy server
(OpenScape Voice). This is necessary for outgoing calls. SIP registrar address contains the
IP address or host name of the registration server, to which the phone will send REGISTER
messages. When registered, the phone is ready to receive incoming calls. SIP gateway ad-
dress gives the IP address or host name of the SIP gateway. If configured, the SIP gateway is
used for outgoing calls; otherwise the server specified in SIP server address is used. A SIP
gateway is able to perform a conversion of SIP to TDM, which enables to send calls directly
into the public network.
With firmware V2, enhanced survivability using DNS SRV is available. To make use
>
of it, a special configuration is required. For details, please refer to Section 3.5.9,
"Resilience and Survivability".
