Proxy redundancy

[AndrewGold]

Hi all.

I have met a problem with proxy redundancy on W52P-25.73.0.40.
According with docs "Using server redundancy", NAPTR, SRV and A recordes had added to DNS. I used NAPTR for transport, and domain name (no FQDN) in SIP Server 1 field. But the phone are not trying to send DNS NAPTR request to DNS, instead that it send register request to the DNS IP address.

Here is my DNS settings (zone: bk.local):

IN NAPTR 100 50 "s" "SIP+D2U" "" _sip._udp.bk.local

_sip._udp SRV 0 1 5060 sip.bk.local
_sip._udp SRV 2 1 5060 sip3.bk.local

A sip.bk.local 192.168.192.10
A sip3.bk.local 192.168.192.197

Any help will be appreciated.
