From 4f7f8a7e95aa344ba31ffab4da4be52952cf50d1 Mon Sep 17 00:00:00 2001 From: Alexander Traud Date: Tue, 11 Oct 2016 13:55:13 +0200 Subject: chan_sip: Support nat=auto_comedia or nat=force_rport,auto_comedia. In the SIP channel driver chan_sip, auto_comedia was expected to be used in tandem with auto_force_rport. Or stated differently: Only when auto_force_rport was chosen (the default), auto_comedia worked. This change allows auto_comedia to be set independently of the state of (auto_)force_rport. For example, nat=force_rport,auto_comedia is useful for IPv4/IPv6 Dual Stack deployments when IPv6 clients are behind a Firewall.
