Release Notes

4 Release Notes for Cisco Small Business SPA51X IP Phone Firmware Version 7.5.3
Release Notes
HTTPS Support
Secure HTTP (HTTPS) is now supported for uploading, downloading, and
provisioning. HTTPS is supported on phones that are part of a SIP call control
system.
HTTP Put Method Support
For the HTTP Report Method field, the put option is now available. This is the HTTP
method used when the server invokes the phone to send a configuration file
report using the HTTP protocol. This parameter is configured in the Voice >
Provisioning tab in the management interface.
New Report Rule for status.xml Data
The phones can now report the status.xml data if [--status] is specified in the
report rule. See the Cisco SPA500 Series, SPA300 Series, and WIP310 IP
Phone Administration Guide for more information.
VeriSign CA Support
The phones now support VeriSign CA certificates.
Special Character (#) in SIP INVITE Messages
A new parameter is added to the Voice > SIP tab, in the SIP Parameters section.
Normally, the IP phone sends a “%23” (escape) as part of the message when the
special character # is included in the SIP INVITE message.
This can cause problems with some telephony servers that need to receive the #.
The new parameter, “escape special character,” is added. When set to yes (the
default), the phone sends a “%23” (escape) as part of the message when the # is
included. When set to no, the # is sent directly and the escape (%23) is not used.
