vvx 310 for s4b questions

Hi , 


1. If we don't have Windows DHCP options , Can I provision the sfb server information to the hard phone and using PIN to login?

I know BTOE software can help to login easily but they may not have computer with connect to the Lync Phone.


2, If the POE network disconnet, VVX phone can auto login after few minutes or hours? I have tested if unplug and plug  the POE network VVX can cache the information and login automatically. They have some branch office , if the network have problem they don't want go on-site to login manually on every VVX phones .

1. The DHCP options are required in order to use PIN auth. This can be setup using almost any DHCP server, it does not have to be a Windows DHCP server.


2. The VVX phones can autologin if powered off for hours even a few days is normaily fine. As long as you are on a recent version you can log the phones in using the Web interface. If you set up a provisining server you can also put the phones credentials in the phones over ride file so it can login with no interaction.


Lync DHCP Options for PIN Auth.


There is also a new Skype for Bussiness board!
