Unregister on Reboot | Default is No. If set to yes, the SIP user will be unregistered on reboot. | |
Register Expiration | This parameter allows the user to specify the time frequency (in minutes) the HandyTone ATA | |
| will refresh its registration with the specified registrar. The default interval is 60 minutes (or 1 | |
| hour). The maximum interval is 65535 minutes (about 45 days). | |
Early Dial | Default is No. Use only if proxy supports 484 response |
|
Dial Plan Prefix | Sets the prefix added to each dialed number |
|
No Key Entry timeout | Default is 4 seconds. User can short or extend that depends on digits dialed | |
Use # as | This parameter allows the user to configure the “#” key to be used as the “Send”(or “Dial”) | |
Send Key | key. Once set to “Yes”, pressing this key will immediately trigger the sending of dialed string | |
| collected so far. In this case, this key is essentially equivalent to the “(Re)Dial” key. If set to | |
| “No”, this # key will then be included as part of the dial string to be sent out. | |
Local SIP port | This parameter defines the local SIP port the HandyTone ATA will listen and transmit. The | |
| default value is 5060. |
|
Local RTP port | This parameter defines the local | |
| 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 is 5004. |
|
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 HandyTone ATAs are behind the same NAT. | |
NAT Traversal | This parameter defines whether the HandyTone ATA NAT traversal mechanism will be | |
| activated or not. If activated (by choosing “Yes”) and a STUN server is also specified, then the | |
| HandyTone ATA will behave according to the STUN client specification. Under this mode, the | |
| embedded STUN client inside the HandyTone ATA will attempt to detect if and what type of | |
| firewall/NAT it is behind through communication with the specified STUN server. If the | |
| detected NAT is a Full Cone, Restricted Cone, or a | |
| will attempt to use its mapped public IP address and port in all the SIP and SDP messages it | |
| sends out. |
|
| If this field is set to “Yes” with no specified STUN server, then the HandyTone ATA 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. |
|
| The interval of sending blank UDP packet to keep NAT “pin hole” open, default is 20 | |
Use NAT IP: | NAT IP address used in SIP/SDP message. Default is blank. |
|
| SIP Extension to notify SIP server that the unit is behind the NAT/Firewall. | |
Firmware Upgrade: | This is the IP address of the configured TFTP server. If selected and it is | |
Via TFTP Server | the HandyTone ATA will attempt to retrieve new configuration file or new code image from | |
| the specified TFTP server at boot time. It will make up to 3 attempts before timeout and then it | |
| will start the boot process using the existing code image in the Flash memory. If a TFTP server | |
is configured and a new code image is retrieved, the new downloaded image will be verified and then saved into the Flash memory.
Be careful when the TFTP is in progress (the LED will flash in red fast). Do NOT interrupt the process (especially the power supply) otherwise will cause the device dead. Be patient as in some network this process will take more than 15 minutes.
