From 4c6e1bd0a5eaf3e1ebc09ad77f13116c9f2fac64 Mon Sep 17 00:00:00 2001 From: David Vossel Date: Wed, 15 Apr 2009 22:08:40 +0000 Subject: [PATCH] National prefix inserted even when caller ID not available When the caller ID is restricted, the expected behavior is for the caller id to be blank. In chan_dahdi, the national prefix is placed onto the callers number even if its restricted (empty) causing the caller id to be the national prefix rather than blank.
