[cisco-voip] No inbound call signaling

[Ryan Huff]

Jamie,

Is there a plar on the voice port going somewhere you are not expecting maybe?

Have you tried a new cable from the demarcation to the router?

If the telco is using anti-tinkle circuits, you may need to play around with the ring in frequency.

You may also need to adjust the dc-offset voltage.

Thanks,

Ryan

Hello all,

I have a weird one. I'm in a rural area for a customer and I can't get inbound calls on the FXO port to generate any debugs of any kind. I can call outbound all day and see debugs when doing so. I've put a phone on the end of the cable going into the router and verified inbound calls ring in from the PSTN. However the second it's connected to the FXO port I get nothing on the CLI. We've replaced PVDM and FXO card, even tried a different router. I'm thinking it may be possibly be an inbound ringing current issue. Thoughts anyone?
