PSTN call to analog phone on FXS VG200 fails

Hi,

I have a VG200 analog gateway with fxs ports and vic-2BRI to the pstn network configured as H323 gateway. IOS Version is 12.2(4.2).

CCM Version is 3.1(2c).

Unity is not installed yet so I'm trying to use an "old" analog phone with integrated answering machine. I configured forward no answer on IP Phones to this analog phone (n°6014) on the VG200 port (1/0/0) trhough a route pattern to this gateway in the CCM.

When call are forward to this analog phone an error occurs and call is dropped. Direct connexion from PSTN to this phone are dropped either with the same error.

Calls from an IP phone to the analog phone work fine.

H323 conf on the VG 200 :

!

call rsvp-sync

isdn switch-type basic-net3

isdn voice-call-failure 0

!

interface BRI1/0

Re: PSTN call to analog phone on FXS VG200 fails

Try adding the command "voice call send-alert" which will send an alert message to the PSTN instead of the progress seen above
