when i receive a call from a mobile phone, for example from the number
333-77777777 to the virtual number 0465-777777

i see in the logs

call from 333-77777777 to 465-77777777

if i call from 0465-777888 to 0465-777777

i see in the logs

call from 465-777888 to 465-7777

why the first 0 is never displayed?
and why if the call comes from an ISDN line the DID isn't totally displayed?

thanks
