The firmware 650B2 for the M400 was pulled from our server due to some issues we verified on it, and it isn't publicly available, our developers are working on a new release but we do not have a time frame for now.
Thanks for the quick reply! With my new purchased M400, I am on stock version 610B4. I try to connect to my local 3CX SBC 18.1.36 and fail. Do you know if 610B4 firmware is working with 3CX SBC version 18.1.36, or do I require the 650B2?
Thanks a lot, Chris GAR! In SIP Log of the M400, it states
Received from udp:192.168.0.101:5060 at 19/04/2023 10:04:21 (378 bytes) SIP/2.0 500 Server Internal Error
So I think there's something wrong with the SBC. It runs on a Raspberry Pi 4, and in 3CX Start-Up edition, the SBC appears online (with that green square symbol).
If the SBC comes up correctly, I advise you to look at the SNOM instead, check if the outbound proxy is the IP of your SBC. In principle, nothing specific, here is my configuration for the SNOM if that can help you.
Thanks a lot for your assistance, highly appeciated! My settings seem to be fine, and in the log message, 192.168.0.101 is the 3CX SBC. What I found out further is this in the SIP Log:
Sent to udp:224.0.1.75:5060 at 19/04/2023 10:04:21 (718 bytes)

SIP/2.0 500 Server Internal Error
[…]
So, the M400 tries to connect to 224.0.1.75 – I am not quite sure, if the Server Internal Error is caused by the SBC or that IP address 224.0.1.75, where it tries to connect to.
Edit: I just learnt that 224.0.1.75 seems to be a SIP multicast address. So, it seems like the Server Internal Error was caused and given by the SBC.

Hi,
Our M400 in 610.3 works on the SBC 18.1.36 but I think it is more stable on the 650.2

Any idea?

Does it work in STUN?
This would allow to check if the SBC is working properly.
End user Benjamin Gasser
I don't have any STUN devices, just the M400 and the M85s. With the mobile apps on Android and iOS, things are working well.
Update: I set up an SBC on my Windows office machine (192.168.11.52). Same behaviour in SIP Log of M400 also here:

It works today. I have no clue why.
Thanks again, Chris GAR, for your efforts!
