Override DNS on Polycom 550 on corporate network

[Anonymous]

Hi !

I am looking for a way to use the Polycom phone profile to override or statically set a DNS server information. The Polycom phones sits within a customer network (Private address space). I am trying to statically set the DNS information (remotely via phone profille) on the phone. (The phone is running SIP version 3.1). I found some information in the following manual (page A124-A127).

 "http://supportdocs.polycom.com/PolycomService/support/global/documents/support/setup_maintenance/pro...

I tried a number of different combinations but the phone is still sending all DNS requests to the customer network DNS instead of the specified one. I added the following to the mac-phone.cfg file (also tried putting it in the sip.cfg file to see if I can get it to work):

<device>

<device.dns device.dns.altSrvAddress="218.xxx.yyy.zzz" device.dns.domain="" device.dns.serverAddress="203.xxx.yyy.zzz">

      <device.dns.altSrvAddress device.dns.altSrvAddress.set="1">

      </device.dns.altSrvAddress>

      <device.dns.domain device.dns.domain.set="0">

      </device.dns.domain>

      <device.dns.serverAddress device.dns.serverAddress.set="1">

      </device.dns.serverAddress>

    </device.dns>

</device>

Any ideas on how to achieve this.

Thanks

Hi Lion

Is the phone using DHCP?  I would imagine that the DHCP string is being seen by the phone first before the config files are loaded into the phone.  Try disabling DHCP then set the ip, mask and gw in the config and see if that helps...
