ID used for authentication, usually same as SIP user ID, but could be different and
decided by ITSP.

Password for ATA to register to (SIP) servers of ITSP. Purposely left blank once saved
for security. Maximum length is 25.

request
SIP Registration
This parameter controls whether the HT503 needs to send REGISTER messages to
the proxy server. The default setting is “Yes”.
Unregister on Reboot
Default is No. If set to yes, the device will first send registration request to remove all
previous bindings. Use only if proxy supports this remove bindings request.
Outgoing Call w/o

This parameter lets users place outgoing calls even when not registered (if allowed by
ITSP) but it’s unable to receive incoming calls.
Register Expiration
This parameter allows the user to specify the time frequency (in minutes) the

interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45
days).

This parameter defines the local SIP port the HT503 will listen and transmit. The default
value for FXS port is 5060.
Local RTP port
This parameter defines the local RTP-RTCP port pair the HandyTone ATA 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 is
5004.
