It uses system level stuff to do the DNS resolution, that has its own timeouts that Asterisk doesn't control. -- Joshua C.

Hi, thanks for responding. No ICE or STUN. Some of the servers have entries for themselves in /etc/hosts and some rely on external DNS. That is not by design, it's just how it happened and I shall sort that out. I can't figure out how whether the delays were on only the ones without /etc/hosts entries, but I can be sure that some without those entries definitely did experience those delays. Does 5 seconds match some sort of DNS timeout within Asterisk that could have been the cause? Cheers, Kingsley. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
