STEP 2 Click Admin Login and advanced. STEP 3 Click the SIP tab. STEP 4 Under SIP Parameters, make the necessary configuration changes to the fields shown in the following table and click Submit All Changes. Parameter Description SIP Reg User Agent Name User-Agent name used in a REGISTER request. If not specified, the SIP User Agent Name is also used for the REGISTER request. Defaults to blank. SIP Accept Language Accept-Language header used. If empty, the header is not included. Defaults to blank. DTMF Relay MIME Type MIME Type used in a SIP INFO message to signal a DTMF event.

Remove Last Reg If set to yes, removes the last registration before re-registering (if the value is different). Defaults to no. Use Compact Header If set to yes, the Cisco IP phone uses compact SIP headers in outbound SIP messages. If inbound SIP requests contain normal (non-compact) headers, the phone substitutes incoming headers with compact headers. If set to no, the Cisco IP phone uses normal SIP headers. If inbound SIP requests contain compact headers, the phone reuses the same compact headers when generating the response, regardless of this setting. Defaults to no. Escape Display Name Setting this parameter to yes encloses the configured Display Name string in a pair of double quotes for outbound SIP messages. Any occurrences of or \ in the string is escaped with \ and \\ inside the pair of double quotes. Defaults to yes. 90 Cisco SPA and Wireless IP Phone Administration Guide
