IPv6 and Why Email Didn't Work Anymore
snom ONE has supported IPv6 since the early days of PBXnsip, and while we're still waiting for service providers to fully embrace IPv6, there are more practical issues to address. One of the challenges is the handling of DNS records for IPv4 and IPv6 (A and AAAA). As more services add AAAA records, the problem arises when clients without IPv6 connectivity still receive those records, which leads to connection issues. A recent example was Gmail, where the snom ONE email client stopped working. The solution was to prioritize IPv4 records first, though this workaround isn't a permanent fix, as IPv4 will eventually become obsolete.
