Can not get the Alcaltel FXO card to detect ringing coming from VG224 port. The Alcaltel FXO card works fine using an analog port from Nortel PBX or Verizon POTs line. On the VG224 voice port, I tried changing the ring frequency, ring dc-offset voltage, idle-voltage, ring cadence, reversed the tip/ring connections, all with no help. All other functions with VG224 and the Alcaltel FXO/FXS are working. Any thoughts on what else to check?

Which exact IOS are you running ?
03-10-2010 08:42 AM
Running: vg224 Software (vg224-I6S-M), Version 12.4(11)T4
Also have 20 other ports up and working for various faxes, modems, telephones. Problem is with integration with Alcaltel D448 FXO/FXS cards.

Update IOS just to be on the safe side. Sometime things are misteriously resolved that way.
Otherwise you might try a ring booster:
