DESCRIPTION
Select this to have the GPON Device send fax messages as UDP or TCP/IP packets
through IP networks. This provides better quality, but it may have inter-operability
problems. The peer devices must also use T.38.
Enter the number of seconds your SIP account is registered with the SIP register server
before the registration is downgraded to 'inactive' and all SIP functions for the account
are blocked. The GPON Device automatically tries to re-register your SIP account when
one-half of this time has passed. (The SIP register server might have a different
expiration, which takes priority over this setting.)
Enter the number of seconds the GPON Device waits before it tries again to register the
SIP account, if the first try failed or if there is no response.
Select the DSCP (DiffServ Code Point) number for SIP message transmissions. The
GPON Device creates Class of Service (CoS) priority tags with this number to SIP traffic
that it transmits.
Select the DSCP (DiffServ Code Point) number for RTP voice transmissions. The GPON
Device creates Class of Service (CoS) priority tags with this number to RTP traffic that it
transmits.
Control how the GPON Device handles the tones that your telephone makes when you
push its buttons. You should use the same mode your VoIP service provider uses.
RFC2833 - send the DTMF tones in RTP packets.
InBand - send the DTMF tones in the voice data stream. This method works best when
you are using a codec that does not use compression (like G.711). Codecs that use
compression (like G.729 and G.726) can distort the tones.
SIPInfo - send the DTMF tones in SIP messages.
Select the protocol your VoIP service provider uses for sending SIP traffic.
UDP - User Datagram Protocol.
TCP - Transmission Control Protocol.
TLS - Transport Layer Security. This is used for secure transmissions.
