Phone doesn't ring on VoIP

[hodgsodc]

I have recenlty switched my telephone service with iDNET from analogue to VoIP. Since I wanted to retain my analogue phone with bell ringer, I chose to Cisco ATA 191 route. The result is only partially satisfactory. I can make ourgoing calls but not incoming as the bell does not ring. In fact if I pick up the receiver at the right time, I can hear an incoming call. I understand from others on the internet that the problem is probably that the ringer voltage generated by the ATA191 in too small. However the ATA191 is programmable, so I would like to be able to programme it myself or have iDNET do it for me. So far "Support" has not been able to offer any solution.
Can anyone please shed light on this problem?

Hi David, and

I'm no expert on these matters but I'm sure someone will be able to help soon.

Older phones need an ATA adapter lead with a ring capacitor.
