Public Distribution Lists, page 5.
Configuring Cisco Unified CME SIP Options for RFC Compliance
Cisco Unity Express provides the protocol command to ensure compatibility with all Cisco IOS
releases. Cisco IOS Release 12.4(2)T and earlier releases are not RFC 3261 compliant. The lack of
compliance causes the Cisco Unity Express software not to interoperate properly with those older
Cisco IOS releases when sip-notify or sub-notify are used for DTMF.
Required Data for This Procedure
The release number of the Cisco IOS software running on your call control platform.
