Weird issue here.
We have a VG224 configured with SCCP and we are experiencing an issue with an analog phone not ringing (audible). The call flow is such that the call will go out the VG224 FXS over an OPX line and ring down an analog phone. The issue is that the analog phone does not ring so that the end user can hear that they have an incoming call. The calling party DOES hear ringback and if the called party (analog phone) picks up they will have 2-way audio. The issue is that there is never any audible ringing on the analog phone side.
VG224 running 12.4(24)T2. Other analog devices on this VG224 work with no issues. Its only a couple OPX lines that are having this issue.
