BricLink II works great with LinPhone in either Opus or AAC mode... still more setup needed on the remote end than the Opus.

I agree with your assessment of the Z/IP One.  I can connect with LinPhone in G.722 mode, or with other codecs in G.722 mode... even when both codecs support Opus, AAC, or others... Not sure why Telos limits inter-codec operations to G.722?

I have not tried Linphone.  However, I have Telos Z/IP Ones rather than Comrex units and the Telos boxes are more finiky about connecting with non-Telos gear or apps such as Linphone.  For example, I CAN connect using Luci Live Lite because it is only G.722 and Telos limits NACIP connections to G.722 for reasons I have yet to fully understand.  However, the full-blown Luci Live, which offers many more algorithms, will still only connect using G.722.  It doesn't sound bad, but the frequency response promised by the Opus codec is broader than the 7 kHz limit of G.722.  So if I want to get better audio than G.722 from guests with minimal hassle, it looks like I'll likely be getting new hardware of some sort.  Perhaps a BricLink II paired with Linphone would be a better option.  Is anyone using that?  (The price of the Access is more than I really want to spend at this point.)
