Appendix B Configuring Non-Cisco Phones That Are Running SIP
Configuration Differences for Phones That Are Running SIP
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 third-party phones that 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 running SIP; see following examples:
• Ensure proxy address in the phone is the IP or Fully Qualified Domain Name (FQDN) of Cisco
Unified Communications Manager.
• Ensure directory number(s) in the phone match the directory number(s) that are configured for the
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 must identify
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=”126c0643a4923359ab59d4f53494552e”
