SIP Interop Tweaks
Accept INVITE's from Anywhere: By default, registered interfaces will reject INVITE's not coming from the SIP server with "305 Use Proxy".
Enforce Sending Complete:
No Inband Information on Error: Regards ISUP-to-SIP signaling. On receipt of DISCONNECT with progress indicator on an early call (not yet connected) a "183 Session Progress" is going to be sent in SIP in order to make the caller hear the inband announcement (tone pattern) provided by the PSTN. The caller will terminate the call then. If this option is enabled, a final error response will be sent to the caller and no inband announcement will be heard.
From Header when Sending INVITE:
Identity Header when Sending INVITE:
Notes (SIP specific)
domain/realm
normally, it is sufficiant to specify domain/realm. the DNS is queried then with this name to obtain the DNS SRV entry _sip._tcp or _sip._udp, respectively. this may result in a list of service addresses, ordered by priority and weight.
if no SRV entry is found, then the configured domain is queried as a host name.
if there is a Server Adress configured, then no DNS SRV lookup is done and the address provided is used. The domain/realm is used only for SIP URIs. If there is no domain/realm, the Server Address is used for building SIP URIs.
The two Server Address fields will be DNS-resolved.
[ will be enhanced in V7 ]
Both DNS lookups (HOST and SRV) currently only works for registered GWs (not Gateways without registration).
