Accounts Active

Activates/Deactivates the accounts. The FXS port configuration will not change if disabled, although the port will not be operational, in this state, there will be no dial tone when picking up the analog phone and making/receiving calls will not be possible.

Primary SIP Server

Configures SIP server IP address (Supports both IPv4 and IPv6 addresses) or domain name provided by VoIP service provider. (For example: sip.mycompany.com, IPv4: 192.168.5.170, or IPv6: 2001:1260:1:277::3). This is the primary SIP server used to send/receive SIP messages from/to HT8xx.

Failover SIP Server

Defines failover SIP server IP address (Supports both IPv4 and IPv6 addresses) or domain name provided by VoIP service provider. (For example: sip.mycompany.com, IPv4: 192.168.5.170, or IPv6: 2001:1260:1:277::3)This server will be used if primary SIP server becomes unavailable.

Prefer Primary SIP Server

Selects to prefer primary SIP server. The account will register to the primary Server if registration with the Failover server expires.

 
Will register to Primary Server if Failover registration expires: If failover server registration ends, the client reverts to the main server.

 
Will register to Primary Server if Primary Server responds, need to enable SIP OPTIONS/NOTIFY Keep-Alive: Client registers with the main server if it's responsive, requiring keep-alive methods.

 
No: The client doesn't prioritize the main SIP server.

 
The default is No.

Outbound Proxy

Specifies IP address (Supports both IPv4 and IPv6 addresses) or domain name of outbound Proxy, or media gateway, or session border controller. (For example: proxy.myprovider.com, or IP address, if any: IPv4: 192.168.5.170/ IPv6: 2001:1260:1:277::3). Used by HT801/HT802 for firewall or NAT penetration in different network environments. If symmetric NAT is detected, STUN will not work, and only outbound proxy can correct the problem.

Backup Outbound Proxy

Configures the backup outbound proxy to be used when the “Outbound Proxy” registration fails. (For example: proxy.myprovider.com, or IP address, if any: IPv4: 192.168.5.170/ IPv6: 2001:1260:1:277::3). By default, this field is left empty.

Prefer Primary Outbound Proxy

If the user configures this option to “Yes”, when registration expires, the device will re-register via primary outbound proxy.

By default, this option is disabled.

allows users to add the actual domain name, it will override the the header. This is an optional configuration.

Allow DHCP Option 120 (override SIP Server)

Configures the HT802 to collect SIP server address from DHCP option 120.

Default is No.

Specifies if “sip” or “sips” will be used when TLS/TCP is selected for SIP Transport. The default setting is “sips”.

Use Actual Ephemeral Port in Contact with TCP/TLS

Controls the port information in the Via header and Contact header. If set to “No”, these port numbers will use the permanent listening port on the phone. Otherwise, they will use the ephemeral port for the connection. The default setting is “No”.

NAT Traversal

Indicates type of NAT for each account. This parameter configures whether the NAT traversal mechanism is activated. Users could select the mechanism from No, Keep-alive, STUN, UPnP.

Default setting is No.

Authenticate Password

Specifies account password provided by VoIP service provider (ITSP) to register to SIP servers.

Name

Chooses a name to be associated to user.

DNS Mode

Selects DNS mode to use for the client to look up server. One mode can be chosen. Default is A Record.

A Record: resolves IP Address of target according to the domain name.

SRV: DNS SRV resource records indicate how to find services for various protocols.

NAPTR/SRV: Naming Authority Pointer according to RFC 2915.

Use Configured IP: if SIP server is configured as domain name, device will not send DNS query, but will use “Primary IP” or “Backup IP” to send SIP message if at least one of them are not empty. It will try to use “Primary IP” first, after 3 tries without any response, it will switch to “Backup IP 1”, then “Backup IP 2”, and then it will switch back to “Primary IP” after 3 re-tries.

DNS SRV use Registered IP

When this option is set to “Yes”, when the HT is registered on second SRV and makes an outbound call, it will try the second SRV (registered IP) first.

By default, this option is disabled, and the DNS SRV will use first SRV instead of the registered IP.

DNS SRV Failover Mode

Configure the preferred IP mode for DNS SRV or NAPTR/SRV. If “default” is selected, first IP from query result will be applied; If “Saved one until DNS TTL” is selected, previous IP will be applied before reaches DNS timeout; If “Saved one until no response“ is selected, previous IP will be applied even after DNS time out until it is unreachable.

• Default: If the option is set with “default”, it will again try to send register messages to one IP at a time, and the process repeats.

• Saved one until DNS TTL: If the option is set to “Saved one until DNS TTL”, it will send register messages to the previously registered IP first. If no response, it will try to send one at a time for each IP. This behavior lasts if DNS TTL (time-to-live) is up.

• Saved one until no responses: If the option is set with “Saved one until no responses”, it will send register messages to the previously registered IP first, but this behavior will persist until the registered server does not respond.

Failback Timer

When the primary SBC is up, device will send SIP requests to the primary SBC. If at any point device fails over to the secondary SBC, the SIP requests will stay on the failover SBC for the duration of the failback timer. When the timer expires, device will send SIP requests to the primary SBC, (in minutes. Default is 60 minutes, max 45 days).

Register Before DNS SRV Failover

This feature is used to control whether the device need to initiate a new registration request (following existing DNS SRV fail-over mode) first and then direct the nonregistration SIP request (INVITE) to the new successfully registered server or not.

TEL URI

Indicates E.164 number in “From” header by adding “User=Phone” parameter or using “Tel:” in SIP packets, if the HT801/HT802 has an assigned PSTN Number.

Disabled: Use “SIP User ID” information in the Request-Line and “From” header.

User=Phone: “User=Phone” parameter will be attached to the Request-Line and “From” header in the SIP request to indicate the E.164 number. If set to “Enable”.

Please consult your carrier before changing this parameter. Default is Disabled.

SIP Registration

Controls whether the HT801/HT802 needs to send REGISTER messages to the proxy server. Default setting is Yes.

Unregister on Reboot

Dial Plan

Dial Plan Rules:

1. Accept Digits: 1,2,3,4,5,6,7,8,9,0, *, #, A,a,B,b,C,c,D,d

2. Grammar: x – any digit from 0-9;

a. xx+ – at least 2 digits number;

b. xx – exactly 2 digits number;

c. ^ – exclude;

d. . – wildcard, matches one or more characters

e. [3-5] – any digit of 3, 4, or 5;

f. [147] – any digit 1, 4, or 7;

g. <2=011> – replace digit 2 with 011 when dialing

h. <=1> – add a leading 1 to all numbers dialed, vice versa will remove a 1 from the number dialed

i. | – or

j. Flag T when adding a “T” at the end of the dial plan, the phone will wait for 3 seconds before dialing out. This gives users more flexibility on their dial plan setup. E.g., with dial plan 1XXT, phone will wait for 3 seconds to let user dial more than just 3 digits if needed. Originally the phone will dial out immediately after dialing the third digit.

Example 1: {[369]11 | 1617xxxxxxx} –

Allow 311, 611, 911, and any 10-digit numbers of leading digits 1617

Example 2: {^1900x+ | <=1617>xxxxxxx} –

Block any number with leading digits 1900 and add prefix 1617 for any dialed 7-digit numbers

Example 3: {1xxx[2-9]xxxxxx | <2=011>x+} –

Allow any length of number with leading digit 2 and 10 digit-numbers of leading digit 1 and leading exchange number between 2 and 9; If leading digit is 2, replace leading digit 2 with 011 before dialing.

1. Default: Outgoing – { x+ | +x+ | *x+ | *xx*x+ }

Example of a simple dial plan used in a Home/Office in the US:

{ ^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. | [3469]11 }

Explanation of example rule (reading from left to right):

^1900x. – prevents dialing any number started with 1900

<=1617>[2-9]xxxxxx – allows dialing to local area code (617) numbers by dialing 7 numbers and 1617 area code will be added automatically

1[2-9]xx[2-9]xxxxxx – allows dialing to any US/Canada Number with 11 digits length

011[2-9]x. – allows international calls starting with 011
