Outbound Proxy
(Optional) If a separate Outbound Proxy is being used (different to the SIP Server) the fully
qualified domain name or IP Address can be entered here. In most cases the Outbound Proxy
should be left blank.
Allow Re-Invites
Sets whether re-invite requests are allowed. SIP Re-Invites are used when calls are placed on hold,
during call transfers and to make other changes during call setup. In most cases this should be set
to Yes.
Qualify
If set to Yes the OneStream will send a SIP Option packet to the SIP Server / PBX every 60
seconds to confirm that the Server / PBX is available. Default is No.
DTMF Mode
Sets the format that DTMFs will be sent during a SIP call. Options are:
RFC 2833 (Default) – send DTMFs out-of-band as RTP payload according to RFC 2833
SIP INFO – send DTMFs out-of-band as SIP INFO packets
Inband – send DTMFs in-band within the audio of the phone conversation
Audio Codecs
Select the available audio codec and the priority with which they will be used (1 is highest priority,
3 is lowest priority). To use less than 3 codecs set the disused entries to “-None-“. Available codecs
are:
G.711u - Ulaw uncompressed codec, requires approx. 85Kbps per call
G.711a - Alaw uncompressed codec, requires approx. 85Kbps per call
G.729 – Compressed codec, requires approx. 25Kbps per call
