MP58 Pro downgrade to SIP

[dobei]

Hello everyone,
I bought an MP58 Pro, unfortunately I didn't find out more about the phone in advance. I thought it was a normal SIP phone with "Teams" functions. Unfortunately it is exactly different, it is a specialized "Teams" phone which also offers the possibility of limited SIP.
For my everyday work I need SIP with BFL etc. The API to use PhonerSuite is also missing

Hence my question, is there also a pure SIP firmware for the MP58, such as with the T58?
(I have already tried to flash the T58 firmware, but this is aborted. I think the hardware is the same???)

Thanks in advance for any info.

The MP58 is not the same as the T58A/T58V, I think it is the same as the T58W.

To upgrade from the Teams firmware to SIP you'd probably need to follow the Yealink How to Upgrade to Yealink SIP Edition from Teams or SFB Edition guide.

And in the end, the firmware to download would be the T58W one https://support.yealink.com/en/portal/do...62c24e43ed

FYI I just tried and it said invalid hardware when using the T58W SIP firmware on a MP58 Teams.

Also found this NOTE MP series do not support converting between SIP and Teams versions.
