Sangoma Vega 100G

Sangoma Vega 100G/200G/400G Missing 0 on Caller ID

If you have a Sangoma Vega 100G, 200G or 400G gateway connected to a BT ISDN line, you might find sometimes that the Caller ID coming in on phone calls is missing the leading zero.  So you might receive a call that shows as being from ‘7123456789’ instead of ‘07123456789’.

The reason for this is that often an ISDN line doesn’t send the national or international dialling codes but instead a flag in the ISDN message called Type-Of-Number.  This flag can usually contains ‘national’ or ‘international’ as a value which is intended to tell the device connected to the ISDN line (i.e. an ISDN PBX) to add the correct codes to the start of the Caller ID depending on the location/country it is in.  The point of this is that these numbers might not be the same in different areas or countries.

To make the Vega put these numbers in, change the following settings found in the SIP -> Advanced SIP Settings page:

  • National Prefix = 0
  • International Prefix = 00

Then the gateway will add these numbers as long as the ISDN line includes the TON flag (which it should do if it is not sending the 0/00 in the Caller ID).


Vega 400/200/100 firmware recovery

If you have bricked your Vega box during the firmware upgrade process or something similar then it can be recovered.

You will need the following items for recovery.

  • Console cable (RJ45 to Serial converter). Vega 400/200/100 comes with a console cable.
  • Computer running Windows/Linux or Mac.
  • Terminal client such as Hyper Terminal, Minicom or Putty.
  • USB to Serial converter (optional: only required if computer does not have a serial port)

Recovery Procedure:

  • Turn off Vega
  • Connect RJ45 end of cable to console port and connect the serial connector to the serial port on computer.
  • Connect to Terminal client of your choice and set following configuration
  • Speed: 9600
    Data bits: 8
    Parity: None
    Stop bits: 1
    Flow control: None

  • Turn on Vega box and press Enter button a couple of times until the message “Press ‘Y’ to enter Boot Menu ” appears on terminal window.
  • Press ‘Y’

Note: Check the connections if nothing appear on terminal screen.

    1) Download Boot Image (SRec)
    2) Download Firmware Image (SRec) (115K2 Baud recommended)
    3) Config Clear
    6) Switch Boot Partition
    D) Duplicate FLASH
    F) Set Flow Control (currently Hardware)
    Z) Set speed high (115200 Baud)
    E) Exit BOOT and Run Firmware

  • Finally press 6 to choose option 6 i.e. switch boot partition press 6 and wait couple of seconds. This setting will change the partition to older firmware version press E to exit and reboot to old firmware.

After the reboot the Vega should come back with older firmware and settings.
