Subject: res_pjsip_session: Rewrite o= with external_media_address.
X-Git-Tag: 13.19.0-rc1~206^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dcbf61a31e5a86452e6dd05948b10a024c6069af;p=thirdparty%2Fasterisk.git

res_pjsip_session: Rewrite o= with external_media_address.

PJSIP allows a domain name as external_media_address. This allows chan_pjsip to
be used behind a NAT with changing IP addresses. The IP address of that domain
is resolved to the c= line already. This change sets also the o= line to that
domain.
