Need help with IAX2 on Asterisk using the voip.ms provider

[Matt Minuti]

I set up an Asterisk server running on FreeBSD for a company probably 8-10
years ago, using Vitelity (back when they offered services for
brick-and-mortar small businesses). I believe it used IAX2, and the actual
phones were bottom-of-the-line Grandstream DECT cordless units that
connected to the Asterisk box through SIP over SSL (probably with a
self-signed cert knowing me). That knowledge is probably out of date now,
unfortunately.

For my office, I'm using voip.ms and having the phones directly connect to
their servers via subaccounts. It's working great - I only have one DID
hooked up, but depending on what the caller presses in the IVR (voice menu
thing), it rings different sub-accounts in groups. I expected it to be a
holdover solution until I had the time to set up a proper Asterisk install,
but it's working well enough that I'm likely to keep it. That said, I
initially had a lot of difficulty keeping the registration attached to the
hardphones, while the softphones never had issues. Although it makes
absolutely no sense, I want to say that there was a codec incompatibility,
because once I turned off one of the codecs (forget which) on a hardphone,
that hardphone has maintained registration forever.

Have you checked the guides on the voip.ms wiki? I found them to be pretty
helpful, particularly when I looked at the guides for hardware I don't
actually have, so that I could cross-reference and get a sense as to what
MUST be set versus what is flexible.
