SENDDTMFLAST: This setting is not normally required. It can be used to reorder the codec
sequence to end points, so that the DTMF codec is sent last. Only required if problems are
encountered with certain types of end point. Default value: OFF
RTPTOS: Sets the value of the TOS/Diffserv field in the UDP packets carrying RTP data. This
value prioritises traffic over the network to provide QoS (Quality of Service) for voice, see
RFC2474. Valid values are 1->63 (Default value = 46
)
SINGLEPTIME: Certain endpoints can only accept a single audio packet time regardless of
CODEC (see AUDIO page). This field forces a single packet time to the value set in ms.
Valid values are 0 to 100, where 0 disables the feature allowing codecs to use the packet
times set on the AUDIO page. Default value 0.
SENDMULTIPARTMIME: This option is for future enhancement and should always be set to
‘OFF’. Default value OFF.
NEWBRANCHONAUTHBYE: This is a legacy option that is no longer used, and must always
be set to 'ON'. Default value 'ON'.
MODE: This field sets whether multiple proxies and registrars are used serially or
concurrently. If set to SERIAL the phone will attempt to register with the next priority registrar
if registration with the current one fails. If set to MULTIPLE it will attempt to maintain
registration with all enabled registrars, and will use the priority sequence for outbound call
failover. Default value: SERIAL. When only a single proxy / registrar is enabled, set this
value to SERIAL to ensure any registration failure is detected quickly.
REGTIMEOUT: Sets the Registration timeout value (in seconds) that will be suggested by the
telephone to a Registrar. Following the expiry of this timeout, the telephone will be
deregistered and then automatically attempt to re-register. (Value range: 0 to 2
32 -1, default
value: 3600) The registration server can ignore or override this suggested time.
REREGTIMEOUT: Sets a period in seconds after which the phone will force a re-registration
period and the server cannot override it. Disabled if set to zero. Default value 0. This field
can be used to ensure that registration is maintained for this particular phone, regardless of
the general settings on the registration server. For example, if this were an emergency
phone, setting this field to 30 would force re-registration every 30 seconds even if the server
normally only refreshes registration once an hour. In this way, if the proxy server fails or
becomes unavailable, the phone can detect it quickly and either attempt to register with the
