Subject: res_pjsip_registrar: Don't specify an expiration for static contacts.
X-Git-Tag: 19.0.0-rc1~357
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=921b1a02c4d602fa1f3cd8ebd916956b4a5d4a08;p=thirdparty%2Fasterisk.git

res_pjsip_registrar: Don't specify an expiration for static contacts.

Statically configured contacts on an AOR don't have an expiration
time so when adding them to the resulting 200 OK if an endpoint
registers ensure they are marked as such.
