How often to refresh External Host if used.
NAT Mode
Global NAT settings (Affects all peers and users), is used when Asterisk is on a public IP, communicating with
devices hidden behind a NAT device (broadband router). If you have one-way audio problems, you usually have
problems with your NAT configuration or your firewall's support of SIP+RTP ports.
Local Network identification
You may add multiple local networks. A reasonable set of defaults are set here.
Allow RTP Reinvite
By default, Asterisk tries to re-invite the audio to an optimal path. If there's no reason for APBX to stay in the media
path, the media will be redirected. This does not really work with in the case where APBX is outside and have clients
on the inside of a NAT. In that case, you want to set this option to nonat.
