- Use domain to register – use the domain during registration. In this case, domain will be
transmitted into Request URI of ‘REGISTER’ request;
- Outbound proxy – ‘Outbound’ mode:
 Off - route the calls according the dialplan;
 Outbound - dialplan is needed for outgoing connection, but all calls will be routed
by SIP-server; in case of registration absence subscriber will get station reply, to
manage subscriber service (Supply services management);
 With busy tone - dialplan is needed for outgoing connection, but all calls will be
routed by SIP-server; in case of registration absence VOIP will be unavailable: error
tone will be output in the phone. 'Outbound’ mode is analogue to the device
operation with dialing plan (x.);
- Registration renewal time period (Expires) – time for subscriber port registration on SIP
server. At the average, port registration renewal will be performed after 2/3 of the
specified period;
- Registration Retry Interval – when the registration is unsuccessful, time period between
SIP server registration attempts;
- User call (SIP):
 180 Ringing - 180 reply is sending to caller equipment; caller equipment should
output local ringback tone in line after getting this message;
 183 Progress with SDP - 183+SDP reply is sending to caller equipment; used for
frequency path forwarding to callee reply. In this case, TAU-8.IP will remote send
ringback tone to caller.

of the 'Register' message;
- Ringback at 183 Progress – when checked, 'ringback' tone will be sent upon receiving
'183 Progress' message (w/o enclosed SDP);
- Use Alert-Info header – process INVITE request 'Alert-Info' header to send a non-
standard ringing to the subscriber port. Cadence for a non-standard ringing may be
configured in the section 2.4.9 The ‘Cadence’ submenu;
- Remove rejected media – when option is enabled, passive media will be excepted from
offer-SDP against the RFC3264 advice. Enable the option for coordination with Iskratel
equipment;
- Check RURI user name only - when checked, only subscriber number (user) will be
analyzed, and if the number matches, the call will be assigned to the subscriber port. If
