Telephony Cards - How do I find the serial number of my Sangoma card?

The serial number of a Sangoma card can always be found on the card itself, it is recommended you make a note of the serial number as it entitles you to your warranty support.

Some Sangoma cards allow access to the serial number through DMESG at the Linux CLI, these include the TE13X, TE23X, TE43X, TE820, A4X and A8X series cards.

The TE12X, TE22X, and TE42X do not include this feature and their serial number cannot be retrieved by DMESG.

To retrieve the serial number of a Sangoma card from DMESG run the following command at the linux CLI.

dmesg | grep SN:

Example:
[root@101-28-24-10 ~]# dmesg | grep SN:
wcte13xp 0000:06:09.0: Found a Wildcard TE132/TE134 (SN: 1TE134F - DF05132035553 - B1 - 20130523)
wcaxx 0000:06:08.0: Found a Wildcard A4A (SN: 1A4A00F - DM41142700123 - A - 20131212)

The serial number will start with a DF or DM depending on the model of card.
