Here we are, 48 hours after upgrading to .108. I am impressed, we’ve had no issues.
This is the first firmware in 2 years that Grandstream hasn’t caused me to feel extreme regret, simultaneously fending off angry customers.
We did have 1 particular phone that couldn’t answer any call - It would just sit there and ring, and once the ringing stopped, it would de-register and re-register. This was a GXP2140, and downgrading it fixed it. Not sure if it’s just a bad phone or not. But we have another 300 GXP2140s with other customers without issues.
