fax-protocol-t38 redundancy
fax-protocol-t38 redundancy
Use the Voice Service SIP fax-protocol-t38 redundancy command to set the T.38 protocol high and
low speed redundancy.
Syntax: (config-voice-serv-sip)# fax-protocol-t38 {hs-redundancy
value}|ls-redundancy value}
Example: (config-voice-serv-sip)# fax-protocol-t38 hs-redundancy 1

fax-protocol-t38 signaling
Use the Voice Service SIP fax-protocol-t38 signaling command to configure fax signaling.
Syntax: (config-voice-serv-sip)# fax-protocol-t38 signaling
{nse-only|nse-preferred|sdp-only|sdp-preferred}
Example: (config-voice-serv-sip)# fax-protocol-t38 signaling

Variable Definition
hs-redundancy Configures the number of duplicate packets to transmit during a high-speed
T.38 fax call. Note: Setting the HS Redundancy to greater than 0 will cause a
significant increase in the network bandwidth consumed by the fax call.
Range 0-3 packets, with a default of 0 packets (no redundancy).
ls-redundancy Configures the number of duplicate packets to transmit during a
low-speed T.38 fax call machine protocol.
Range 0 to 4 packets (0 = no redundancy), with a default of 3 packets.
Variable Definition
nse-only Named Service Element (NSE) will be the only method tried without any
attempt to try alternate signaling method to establish connection if it fails.
sdp-only Session Description Protocol (SDP) will be the only method tried without any
attempt to try alternate signaling method to establish connection if it fails.
nse-preferred Named Service Element (NSE) preferred will be the first method tried with an
attempt to try the alternate SDP signaling method to connect if it fails.
sdp-preferred Session Description Protocol (SDP) preferred will be the first method tried
with an attempt to try the alternate NSE signaling method to connect if it fails.
Default.
