Have a 0.X route pattern using OverlapSending. Everything works OK for PSTN calls.
But when trying to CFwdALL to a PSTN destination is impossible, the diverted number is accepted straight away after 2nd digits.
to overcome this, you need to configure an additional route pattern with a wildcard character, such as "0.!" and put this in a separate partition. Create a additional CSS and assign this on the line CallForward-CSS.
