How do I request a SIP licence (to "downgrade" from SFB firmware)?
Hi.

I have a T41S which is currently running an SFB (Skype for business) firmware v66.9.0.80, and I would like to downgrade to a standard SIP firmware (I believe the downgrade to a standard SIP firmware is necessary to be able to configure the phone with "standard" SIP providers).

I have already tried to flash the new firmware using the Settings/Upgrade page but despite there showing no errors, the firmware version remains unchanged.

I have now read in several forum posts that I should upload a SIP licence to the phone before attempting to flash the standard firmware. Could anyone please confirm whether my understanding is correct and, if yes, how do I request this SIP licence?

Many thanks, Jaime
