I am trying to make all calls automatically start with a 9 for outside line. I have enabled number rewriting. Numbers without international prefix will be treated is set to UK(44) and rewrite international numbers is set to other then 900.
This setup works perfect on android but not on ios. When dialling outbound using the app it seems to completely ignore this setup as when it dials 0 it rings other phones in the phone system because its part of the operater group.
Does anyone have any ideas how to get past this? As mentioned, this setup works perfect on android
