Setting DNS SRV from cero

[Maradona]

Hi, im new in this forum. I'm setting the DNS SRV in T20P ipphone model, however in the link http://www.yealink.com/Upload/document/U...545425.pdf there is only a brief help, but my question is, where have i to set two ip address in order to point them to server name?

The help only shows the setting of 'Transport = DNS SRV', but I need to set two IP address with 'redundancy Fail-over'.

Is possible to use only IP addres, rather server name?


Thank you for the answer,
