DTMF Issue with Trunk to trunk Transfer

I’m having issues with passing DTMF to another sip trunk. We set a time condition, After hours the call will be routed to another trunk that has an IVr. we can here the prompt but cant select an option.


you need to post a LOT more info about your setup and the trunks if you want help.

Make sure both trunks use the same DTMF Mode and that the devices on the other ends of the trunks support the chosen mode…
