Hy, i have set the contry code correct (49) in 2.1.5
always when i redial from phone call log, the call failed why number is wrong and the trunk (0) digit is missing.

Currently i take a workaround in Sip SBC, i overwrite the suffix with (00*;00*49;00*0;000*00)
So comes all external calls as 00049xxxxxxxxx
That is working, its not perfect

Can anyone help for correct settings, i have no reference System for view.

The calls comes over a SIP SBC to a BRI ISDN on OfficeServ

What is the required setting for BRI ? National / ISDN
