About a week ago I loaded the v1.19 beta firmware into my m3 system. No obvious problems but I’ve been traveling since then so I haven’t used it a lot. The snom wiki now has instructions on loading the beta from their provisioning server. It’s easy. I’ve set my phone to check for updates once a week. I see that it loaded v1.20 on its own while I was away. The wiki also has release notes on the v1.19 Beta.
I’m still waiting to get an example of the CSV file used for uploading the contact details. I tried a simple one but it was rejected by the phone. There’s obviously more than just the name and number in the file. Snom needs to provide an example so that I can format my contact details appropriately.
