I know this topic has come up a few times on the list before but now I can't seem to find the discussion(s) now. Is it mostly the wireless carriers that support HD Voice / Wideband audio?

Phone auth for incoming calls?
by caalvarez＠gmail.com Aug. 9, 2018

Do most of you have the phones authenticate incoming calls? We haven't been, but occasionally find a router that has unfiltered full cone NAT (Cisco) or that puts one phone on 5060 with no filtering by IP. The result is that the phone will start ringing at random as script kiddies hit the IP and port 5060 trying to find servers to exploit. I don't see a downside to changing to auth, but not having done it outside of a few tests of a small number of phones, I figured I would ask.

SBCs - Ribbon and AudioCodes
by ryan＠finnesey.com Aug. 9, 2018

I am going to have to install a series of SBCs for a? voice offering connected to Microsoft Teams.? We are going to pass the SIP traffic off to a large number of SIP providers.? I would like? to get some feedback from the group on SBCs from Ribbon and AudioCodes . I am leaning towards a software based SBC over an appliance. Would be helpful to get the other members feedback on Ribbon or AudioCodes deployments within their networks. Cheers Ryan

Phone auth for incoming calls?

You're right, most phones have both options also. However I'm not sure how the "same server" is applied for a phone behind NAT. Would the phone actually know where the call came from? I've never tried it. Alex, it does work fine with Asterisk, at least on a small scale test. But the fear of changing something so drastic on thousands of phones lead me to asking about it here.

I am looking to have a conversation with someone at Ribbon Communions formally Sonus that works with CLECs and Service Providers. I am hoping someone on the list may be able to make an introduction.
