 To sign-in:
1. Open the Configuration File page in the Web interface (Management tab > Manual
Update > Configuration File).
2. Configure the parameter using the table below as reference.
Table 2-7: Online Sign-In
Parameter Description
lync/sign_in/support_adal
Determines which online sign-in method option is
used.
 [0] The phone uses the OrgID method option to
sign in.
 [1] (Default) The phone first attempts to use the
ADAL (Azure Active Directory Authentication
Libraries) method option and only if ADAL fails,
the phone uses the OrgID option.
2.2.5.8 Disabling AutoDiscover Web Service Protocol
You can disable AutoDiscover Web Service Protocol [MS-OCDISCWS] which is by default
enabled. AutoDiscover improves discovery of the phone's SIP home server during the sign-
in process. The phone finds its home server URL for a specific Skype for Business account,
based on user credentials. The protocol is especially efficient for Skype for Business online
and hybrid environments, when phones must sign in to a different Skype for Business server
according to the user’s account.
The home server was previously found using DNS SRV records based only on a SIP account
domain [MS-CONMGMT]. If AutoDiscover is unsuccessful, the phone falls back to SRV DNS.

Parameter Description
lync/sign_in/auto_discovery_enabled

[0] Disabled.
 [1] Enabled (Default)
2.3 Copying the Configuration File to the Provisioning
Server
After creating the delta configuration .cfg file as shown in the previous section, copy the file
to the provisioning server (e.g., TFTP server) from which the phones download it when
they're connected and powered up. Make sure DHCP Option (e.g., Option 160) on your
DHCP server is configured with the correct URL pointing to the provisioning server's
directory.
2.4 Triggering Automatic Provisioning
When you connect the IP phones to the network and power them up, the phones' automatic
provisioning is triggered. The phones automatically send out a DHCP Discovery request and
then receive IP address information (e.g., TFTP server's address) in the DHCP Options sent
by the DHCP server. The phones then contact the provisioning server for downloading the
required files (e.g., .cfg file and firmware .img file).
