[Asterisk-Users] Ringer Equivalencies?

[Matt Davies | MattDavies.Net]

So I had my CO replace an IAD at my premesis today because of their hardware
failure. Now, with the new equipment in place, I am unable to even detect
ring on my Adtran 750. I have the same configuration as before, but when I
call my inbound analog lines I cannot see that the Adtran detects the ring -
therefore, it rings forever and forever.

Anyone ever seen this? I know that their IAD is a Cisco 2400 series, but I
don't have a login to the router. Can the ringer voltage be adjusted? Do I
need to adjust something on my 750?

Thanks in advance
