Headers
Complete domain – specify the domain to be used within the
Send information –
header for the INVITE message. This header is used for CLIR transmission to the
counterparty, giving it information on the calling number even in the case of
active CLIR (Calling Line Identification Restriction). By default, the header is
enabled on the SIP Gateway and disabled on the SIP Proxy.
Aliases
Use this option to specify additional Realms (Domains) to be accepted on this port.
Such incoming calls (their INVITEs) will be routed to this port whose Request–URIs
match the given SIP GW or SIP Proxy settings and Domains or Aliases.
RTP
DSP– here you can optimise data to be transmitted. Packets are not sent while
the user is not speaking. VAD stands for Voice Activity Detection.
Generate comfort noise – enable comfort noise generating. As users of classic
analogue lines are used to some background noise, this option simulates a similar
call impression to them.
Mask lost packets – enable optimised computing of probable contents of lost
packets.
QoS
The TOS/DiffServ
packet priority for processing by network elements.
SIP – hexadecimal priority value for SIP packets.
RTP – hexadecimal priority value for RTP packets.
Default values – restore the default values for the two parameters.
