Subject: pjsip_options.c: Allow immediate qualifies for new contacts.
X-Git-Tag: 16.4.0-rc1~7^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=941dead08d1a9a7f1a5932109b663d54edfc5467;p=thirdparty%2Fasterisk.git

pjsip_options.c: Allow immediate qualifies for new contacts.

When multiple endpoints try to register close together using the same
AOR with qualify_frequency set, one contact would qualify immediately
while the other contacts would have to wait out the duration of the
timer before being able to qualify. Changing the conditional to check
the contact container count for a non-zero value allows all contacts to
qualify immediately.
