It will not look up the NAPTR or SRV records at all since you have specified port 5060. Don't specify the port number and it should work. We run a large number of polycom phones without NAPTR records here. However we don't use the outboundProxy attributes at all. We use voIpProt.server.x.address or the phone's reg.x.server.x.address to tell the phones where to register. You shouldn't need to specify outboundProxy unless you need your signaling packets to go to a different server than the registration. -Evan From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Lloyd Aloysius Sent: Tuesday, November 01, 2011 6:23 AM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] FreeSWITCH - Polycom and DNS SRV Brian, Thank you for the reply. I set the voIpProt.SIP.transport="DNSnaptr" <SIP voIpProt.SIP.sdpNewType="0" voIpProt.SIP.tcpEnabled="0"> <outboundProxy voIpProt.SIP.outboundProxy.address="sip.mydomain.com<http://sip.mydomain.com>" voIpProt.SIP.transport="DNSnaptr" voIpProt.SIP.outboundProxy.port="5060 /> </SIP> But this fails to register.

All my DNS SRV records and other phone models [Cisico , Asstra, Yealink] working without any issue. But for Polycom Phones .. I need to specify the "Outbound Proxy" as IP address otherwise phone never register. * voIpProt.SIP.outboundProxy.address="IP ADDRESS"* I could not find why we need to specify "Outbound Proxy? How to avoid using IP address? Does Polycom phones fully support DNS SRV records? Any help is appreciated.
