PROFILE PAGE DEFINITIONS
Settings Options Definitions
Account active When set to Yes this profile is activated
SIP Server SIP Server’s URI or IP address
Outbound Proxy SIP Outbound Proxy Server’s URI or IP address
NAT Traversal
This parameter defines whether the Unicorn 600x NAT
traversal mechanism will be activated or not.
If Choosing No,nothing to do.
If Choosing No, but send keep-alive, the Unicorn 600x will
periodically (every 20 seconds or so) send a blank UDP
packet (with no payload data) to the SIP server to keep the
“hole” on the NAT open.
If choosing STUN and a STUN server is also specified, then
the Unicorn 600x will behave according to the STUN client
specification. Under this mode, the embedded STUN client
inside the Unicorn 600x will attempt to detect if and what
type of firewall/NAT it is sitting behind through
communication with the specified STUN server. If the
detected NAT is a Full Cone, Restricted Cone, or a
Port-Restricted Cone, the Unicorn 600x will attempt to use
its mapped public IP address and port in all its SIP and SDP
messages. If choosing STUN with no specified STUN
server, the Unicorn 600x will periodically (every 20 seconds
or so) send a blank UDP packet (with no payload data) to
the SIP server to keep the “hole” on the NAT open.
If choosing UPNP, the embedded UPNP client inside the
Unicorn 600x will attempt to mapping ports with the router
by upnp protocol.
Ports Using The Profile
Share With One
Common Account
If set to “Yes”, Unicorn60x0 will use the first account among
the FXO PORTS of using the same profile.
If set to “No”, you need configure one port one account in
FXO PORTS page.
Auto Select Idle Port
(For Outgoing Call)
If set to “Yes”, Unicorn60x0 will auto-select an idle Line to
make outbound call to PSTN.
If set to “No”, you need configure one port one account in
FXO PORTS page, then it is the business of SIP SERVER
that it decide which idle FXO Port for outbound call.
Use DNS SRV Default is No. If set to Yes the client will use DNS SRV for
server lookup
User ID is Phone
Number
If the Unicorn 600x has an assigned PSTN telephone
number, this field should be set to “Yes”. Otherwise, set it to
“No”. If “Yes” is set, a “user=phone” parameter will be
attached to the “From” header in SIP request

Hanlong Technology Co., Ltd Unicorn 60x0 User Manual Page 16 of 25
Firmware 1.0.0.29 Last Updated 8/2010
SIP Registration This parameter controls whether the Unicorn 600x needs
to send REGISTER messages to the proxy server. The
default setting is “Yes”.
Unregister on Reboot Default is “No.” If set to “Yes”, then the SIP user will be
unregistered on reboot.
Register Expiration
This parameter allows the user to specify the time frequency
(in minutes) the Unicorn 600x refreshes its registration with
the specified registrar. The default interval is 60 minutes (or
1 hour). The maximum interval is 65535 minutes (about 45
days).
Outgoing call without
Registration
Default is No. If set to “Yes,” user can place outgoing calls
even when not registered (if allowed by ITSP) but is unable
to receive incoming calls.even when not registered (if
allowed by ITSP) but is unable to receive incoming calls.
Local SIP port This parameter defines the local SIP port the Unicorn 600x
will listen and transmit. The default value for FXS port 1 is
5060. The default value for FXS 2 port is 5062.
Local RTP port
This parameter defines the local RTP-RTCP port pair the
Unicorn 600x will listen and transmit. It is the base RTP port
for channel 0. When configured, channel 0 will use this port
_value for RTP and the port_value+1 for its RTCP; channel
1 will use port_value+2 for RTP and port_value+3 for its
RTCP. The default value for FXS port 1 is 5004. The default
value for FXS 2 port is 5008.
Use Random Port
This parameter, when set to Yes, will force random
generation of both the local SIP and RTP ports. This is
usually necessary when multiple Unicorn 600x are behind
the same NAT.
Refer-To Use Target
Contact
Default is NO. If set to YES, then for Attended Transfer, the
“Refer-To” header uses the transferred target’s Contact
header information.
DTMF Payload Type This parameter sets the payload type for DTMF using
RFC2833
DTMF in Audio
This parameter specifies the mechanism to transmit DTMF
digit in audio which means DTMF is combined in audio
signal(not very reliable with low-bit-rate codec),
Default is YES.
DTMF via RFC2833 This parameter specifies the mechanism to transmit DTMF
digit via RTP (RFC2833).
Default YES.
DTMF via SIP INFO This parameter specifies the mechanism to transmit DTMF
digit via SIP INFO.
Default is NO.

Proxy-Require SIP Extension to notify SIP server that the unit is behind the
NAT/Firewall.
USE NAT IP NAT IP address used in SIP/SDP message. Default is
blank.
Preferred Vocoder
The Unicorn600x supports up to 5 different Vocoder types
including G.711 A-/U-law, G.726 (Supports bit rates 32K),
G.723.1, G.729A/B. The user can configure Vocoders in a
preference list that will be included with the same
preference order in SDP message. The first Vocoder is
entered by choosing the appropriate option in “Choice 1”.
The last Vocoder is entered by choosing the appropriate
option in “Choice 6”.
Voice Frames per TX
This field contains the number of voice frames to be
transmitted in a single packet. When setting this value, the
user should be aware of the requested packet time (used in
SDP message) as a result of configuring this parameter.
This parameter is associated with the first vocoder in the
above vocoder Preference List or the actual used payload
type negotiated between the 2 conversation parties at run
time. e.g., if the first vocoder is configured as G723 and the
“Voice Frames per TX” is set to be 2, then the “ptime” value
in the SDP message of an INVITE request will be 60ms
because each G723 voice frame contains 30ms of audio.
Similarly, if this field is set to be 2 and if the first vocoder
chosen is G729 or G711 or G726, then the “ptime” value in
the SDP message of an INVITE request will be 20ms. If the
configured voice frames per TX exceeds the maximum
allowed value, the Unicorn 600x will use and save the
maximum allowed value for the corresponding first vocoder
choice. The maximum value for PCM is 10(x10ms) frames;
for G726, it is 20 (x10ms) frames; for G723, it is 32 (x30ms)
frames; for G729/G728, 64 (x10ms) and 64 (x2.5ms) frames

respectively.
G723 Rate This defines the encoding rate for G723 vocoder. By default,
6.3kbps rate is chosen.
VAD Default is No. VAD allows detecting the absence of audio
and conserve bandwidth by preventing the transmission of
"silent packets" over the network.
Symmetric RTP
Default is No. When set to Yes the device will change the
destination to send RTP packets to the source IP address
and port of the inbound RTP packet last received by the
device.
FAX Mode Default is T.30(Fax Pass-Through), or T.38 (Auto Detect)
FoIP
Fax Tone Detection
Mode Default is Callee. This decides whether Caller or Callee
sends out the re INVITE for T.38 or Fax Pass Through.
