SIP Hardphone w/TLS Recommendations

Hi Everyone,

I am looking to purchase a few SIP hardphones with TLS so that I can have TLS end to end and registration too. I am seeking recommendations for ones that are known to work and that are not too difficult when loading certs/keys/list, etc. and that will work even if the TLS packet is fragmented by TCP.

Thanks in advance for any assistance…
