Configuration Differences for Phones That Are Running SIP
Table B-2 provides a comparison overview of the configuration differences between Cisco Unified IP
Phones and third-party phones that are running SIP.
Use Cisco Unified Communications Manager Administration to configure thi rd-p art y p hon es t hat are
running SIP (see the “Where to Find More Information” section on page B-6). The administrator must
also perform configuration steps on the third-party phone that is r un ning SIP; see fol lowing examp les:
• Ensure proxy address in the phone is the IP or Fully Qualified Domain Name (FQDN) of Cisco
Unified Communications Manager.

device in Cisco Unified Communications Manager Administration.
• Ensure digest user ID (sometimes referred to as Authorization ID) in the phone matches the Digest
User ID in Cisco Unified Communications Manager Administration.
Consult the documentation that came with the third-party phone that is running SIP for more
information.

How Cisco Unified Communications Manager Identifies a Third-Party Phone

Because third-party phones that are running SIP do not send a MAC address, they mu st ide nti fy
themselves by using username.
The REGISTER message includes the following header:
Authorization: Digest
username=”swhite”,realm=”ccmsipline”,nonce=”GBauADss2qoWr6k9y3hGGVDAqnLfoLk5”,uri
=”sip:172.18.197.224”,algorithm=MD5,response=”126c0643a4923359ab 59d4f53494552e”
