I forwarded a number to an external phone number. The call connects and their IVR immediately prompts for an ID as expected. However, whatever key presses I input end up being doubled as I can hear their IVR repeating it back to me saying it is invalid. E.g. If I input an ID of 1234 then press # I hear it repeating back to me "11223344 is not a valid ID". I did confirm that calling their number direct does not result in this and I've used different devices to eliminate that as a potential source. Anyway to solve this? I'm still on 3CX v14.
