Hi!
We have a few Snom 710 that sometimes respond with "505 Version Not Supported" to a "401 Unauthorized" asking for authentication when the phone is sending an INVITE, SUBSCRIBE etc.
This can for example make outgoing calls from the phone fail.
I can't figure out what the problem is here, any ideas?
I have not seen this issue before. I would like to have a look at your logs and settings and try to reproduce the case in the lab. I will open a ticket for you to provide these to us privately.
