Hello,
For our customers, we provided SIP wireless phones from Spectralink SL8440. The only settings that worked was with TLS 1.0. TCP was not possible because NAT far-end.
It worked until the last Edge version, even if the Edges never pushed phone firmware updates. Now, TLS 1.0 is not accepted, so phones cannot register. A newer firmware should certainly solved the issue.
I'm trying to work with support, I'm searching a firmware.
Spectralink has been integrated into Polycom, and then Polycom has been integrated into HP. But I can't find firmware with public availability for SL8440.
Anyone else has also this problem ? Do you have a firmware more recent than 6.0.0.2193 13-Dec-18 ?
Best regards,
