SCCP/VG224 not ringing phones

Phone’s are not ringing, but offhook is showing -43V onhook. When ring comes in I see a voltage drop.  The butt set is fancy and has a reading that shows 38V while offhook (hearing dialtone)

The VG224 data sheet show 50Vrms into 5REN.  What will a volt meter show? I use a volt meter about once every 5 years…

Re: SCCP/VG224 not ringing phones

Can the analog phone make a call outbound or to another phone?  I'd start there.

If it can not, then your gateway is not working.

Do commands such as "show sccp"  and see if if the ports are registered with CUCM.   Check in CUCM the ports are in fact registered. 

You can also run a quick CSIM command and force a call to the analog phone. This at least tell you the gateway can make a call.  It should ring the phone.
