T48U Firmware v. 10.86.188.7
Hello dear Yealink team !

Our company has about a thousand T48U phones. I've begun upgrading their firmware to the last official one - v. 108.86.0.90 .
Since March this year, i've received 20 T48U phones with the 10.86.188.7 firmware. Which one is newer ? Would you recommend changing the 10.86.188.7 version with the last official one from your website - 108.86.0.90 ?

Thanks in advance.

Any firmware with x.x.188.x (188 in the 3rd part) is special localized firmware from Lydis (the Dutch Yealink supplier). Regular standard Yealink firmware are the ones with x.x.0.x.

Thank you for the reply, I thought as much. I've seen such custom firmware's on T49G also. I will be upgrading all these phones to the official firmware then.
