[Asterisk-Users] Feedback from VON expo! Info on * HA andPolycomphone!!

[Douglas Garstang]

Huh? Phones do a NAPTR/SRV lookup in a specified domain to get a list of SRV records to use. The phones don't query the DNS server every time they make a call... they have a cache. You also run primary and a secondary (or two primary) dns servers. It's a simple scalable solution. It's a shame Asterisk doesn't support it.

	Seems to me that it's more logical for the phones to know what their 
	SRV records are than the server.  You shouldn't rely on the dns to 
	ensure that your system is redundant.
