Q1: How many servers may BM6020 register simultaneously

A: BM6020 is able to register two SIP servers simultaneously, and redundancy servers. User can configure the dial peer to route calls between these servers. Please refer "How to use the dial rule" for detail.

Q2: How to use the dial rule

A: BM6020 provide flexible dial rule, with different dial-rule configure, user can easily implement the following function:
----Replace, delete or add prefix of the dial number.
----Make direct IP to IP call
----Place the call to different servers according the prefix.
You can click “Add” to add a new dial rule. Below is the detail setting of the dial-rule:
Phone Number: The Number suit for this dial rule, you can the number as full match or prefix match. Full match means that if the number use dials is the completely same as this number, the call will use this dial-rule. Prefix match means that if prefix of the number that the user dials is the same as the prefix, the call will use this dial-rule, to distinguish from the full match case, you need to add “T” after the prefix number in the phone number setting.
Call Mode: support SIP..
Destination (optional): call destination, can be IP or domain. Default is 0.0.0.0, in this case the call will be routed to the Public SIP server. If you set the destination to 255.255.255.255, then the call will be routed to the private SIP server. Also you can key other address here to make direct IP calls
Port (optional): Configure the port of the destination, default is 5060 in SIP and 1720 for H323
Alias (optional):Set up the Alias. We support four Alias as below. Alias need to co-work with the Del Length:add:xxx, add prefix to the phone number, can set to reduce the dial length.all: xxx, replace the phone number with the xxx, can use as speed dial function.del, delete the first N numbers. N is set in the Del Lengthrep:xxx，replace the first N numbers. N is set in the Del Length. For Example: Use wants to place a call 8610-62281493, then you can set the phone number in the dial rule as 010T, and set the Alias as rep:8610, and set the Del Length to 3. Then all calls begin with 010 will be changed to 8610 xxxxxxxx.Suffix (optional):Configure suffix, show no suffix if not setInstance:
2T rule: If the call starts with 2, the first 2 will be deleted, and the rest number will be sent to private SIP server.3T rule: If the call starts with 3, the first 3 will be deleted, and the rest number with be sent to public SIP server.123 rule: Dial 123 and will send 8675583018049 to your server. Used as speed dial function.0T rule: If the calls is begin with 0, the first 0 will be replace by 86. Means that if you dial 075583018049 and BM8010 will send 8675583018049 to your server.179 rule: when you dial 179 , the call with send to 192.168.1.179, suit for LAN application without set up a sip server.

Q5: How to configure digital map

A: Digit map is a set of rules to determine when the user has finished dialing.
Digital Map is based on some rules to judge when user end their dialing and send the number to the server.
----End With “#”: Use # as the end of dialing.
----Fixed Length: When the length of the dialing match, the call will be sent.
----Timeout: Specify the timeout of the last dial digit. The call will be sent after timeout
----Prefix: User define digital map: [ ] represents the range of digit, can be a range such as [1-4], or use comma such as [1,3,5], or use a list such as [234] x represents any one digit between 0~9 Tn represents the last digit timeout. n represents the time from 0~9 second, it is necessary. Tn must be the last two digit in the entry. If Tn is not included in the entry, we use T0 as default, it means system will sent the number immediately if the number matches the entry.
Example:
[1-8]xxx All number from 1000 to 89999 will be sent immediately.
9xxxxxxx 8 digits numbers begin with 9 will be sent immediately.
911 Number 911 will be sent will be immediately
99xT4 3 digits numbers begin with 99 with be sent after four seconds.
