From 271908886f91169d7ad1407cecdf75d1d8a866d1 Mon Sep 17 00:00:00 2001 From: Alec L Davis Date: Sat, 27 Feb 2010 23:51:28 +0000 Subject: [PATCH] overlap receiving: automatically send CALL PROCEEDING when dialplan starts Following Q.931 5.2.4 When the user has determined that sufficient call information has been received the user shall stop T302 and send CALL PROCEEDING to the network. Previously timeouts were possible if the dialplan took a long time to issue any response back to the network. Verified that our local TELCO also does the same.
