Summary:                    Unable to make ISDN PRI calls after upgrade.
Description: 
After upgrade to SVN-trunk-r204919M from SVN-branch-1.6.2-r203077M we are
unable to make ISDN PRI calls.

reverting back to 1.6.2-r203077M with exactly same configs, works again.

Console output as attached files.

The difference is the extra "Ext: 1  DS1 Identifier: 0" that's not present
using older code.
