I have 1 user out of 20 that cannot dial while in a call. For instance, she’ll call a 1-800 number or a local company that has an IVR system; while in the IVR it’ll say “Press 1 for this option” etc… She’ll press 1 but nothing happens.
This only happens to 1 user and as far as I can tell, her dialing plan is the same as the other users. We are using Trixbox 188.8.131.52
Any advice would be appreciated.
