From fb7247c57c532f2d5e174ef12d6f82e576d65d10 Mon Sep 17 00:00:00 2001 From: Torrey Searle Date: Thu, 15 Jun 2017 10:12:41 +0200 Subject: res_pjsip: Add DTMF INFO Failback mode The existing auto dtmf mode reverts to inband if 4733 fails to be negotiated. This patch adds a new mode auto_info which will switch to INFO instead of inband if 4733 is not available.
