In firmware 1.20 the way call routing was configured has been changed. In this FAQ you are going to find out what is different from previous firmware versions.
On 2N® VoiceBlue MAX following changes have been done:
- In Gateway configuration there is no longer option to select port modes, where you were able to select how calls incoming from one port should be routed (basically allowing you to route calls from FXS to GSM or VoIP). This setting has been merged into LCR table offering an easier configuration.
- LCR table has been redone.
New LCR table allows you to have a complete control over where an incoming call (from VoIP, GSM or FXS interfaces) should be routed to. On pictures bellow you can see examples of differences between the new LCR table and the old one.
1) Explanation of new LCR table
Records in LCR table are read from top to bottow. When a record that matches all conditions is found than the call is going to be sent to outgoing destination specified in that record. Therefore it is important to pay attention to the order in which you have your LCR table records organized!
From (channels/groups) - this parameter specifies where outgoing call originates. In case of VoiceBlue Max it can be:
- all GSM channels
- specific GSM incoming group (1-2)
- FXS ports, all channels
- FXS port, specific channel (0-3)
- VoIP
Prefix list - you must specify either one prefixlist, that the outgoing call number must match, or you can select option All prefixlists, where any outgoing call number that matches at least one prefixlist, will be routed by channel specified under Groups/Tarrifs
Groups/Tarrifs - this parameter specifies if outgoing call should go through a specifis GSM outgoing group, VoIP or FXS interfaces
This way you have a better control over how ougoing and incoming calls are handled and routed. Plus it is possible to route incoming calls from GSM back to GSM which was not possible in older firmware version.
2) Default LCR table settings
Firmware 1.20 | Firmware 1.19 and older |
|---|---|
 |
|
In default there are 5 records which match the default setting of Port modes and LCR table from firmware 1.19 and older | You needed to setup both Port modes and LCR table. |
3) Calls from FXS port 1 are routed directly to GSM outgoing group 1 (dialed number must match prefix list 1), outgiong calls from FXS port 2 are routed directly to GSM outgoing group 2 (dialed number must match prefix list 2), all other calls are left in default
Firmware 1.20 | Firmware 1.19 and older |
|---|---|
 |
|
Calls coming from FXS port 0 (dialed number must match prefix list 1) are routed directly to GSM outgoing group 1. Calls coming from FXS port 1 (dialed number must match prefix list 2) are routed directly to GSM outgoing group 2.
All other calls are routed as is in default | Routing calls from a specific port was dona based on the number that the person was dialing. In this scenario person calling from FXS port 1 must have dialed 01 XXXXXXXXX, caller from FXS port 2 must have dialed 02 XXXXXXXXX. |
4) Incoming call from GSM group 2 (matching prefix list 2) will be routed back to GSM through GSM outoing group 1. Every other incoming call from GSM will be sent to FXS interfaces. Everything else is left in default.
Firmware 1.20 | Firmware 1.19 and older |
|---|---|
 | Sending incoming calls from GSM back to GSM was not possible |
| On picture above you can see how to set a scenario where all incoming calls from GSM incoming group 2 should be sent back to GSM through GSM outgoing group 1 (if dialed number will match Prefix list 2) | Sending incoming calls from GSM back to GSM was not possible |
 | Sending incoming calls from GSM back to GSM was not possible |
On the picture above you can see how to set described scenario. All calls from GSM incoming group 2 (matching prefix list 2) are sent back to GSM. | Sending incoming calls from GSM back to GSM was not possible |
