Hello,
I read in the Cisco CUBE HSRP guide at below link that Cisco CUBE does not preserve call signalling when the primary CUBE goes down and secondary takes its role. Thus you cannot do call transfers, conferences, hold/resume..etc, when CUBE does stateful failover to secondary. However, this document also states that call signalling is preserved from Cisco IOS® Software release 15.1.2T. Can someone confirm if this is true, and if we can do all those functions (transfer, conference, resume/hold..etc) when stateful failover occurs and if CUBE is installed on IOS 15.1.2T??
Thank you.

Hi,
According to this link
The two router used for an HSRP pair should be identical (to ensure the same performance and call capacity level).
Box-to-box redundancy configuration support on SIP-SIP calls flows, the SIP transport can be either UDP-UDP or UDP-TCP
HSRP virtual addresses support only IPv4 addressing.
The media stream of established calls is preserved over a failover, but signaling is not. Therefore, preserved calls cannot be modified (Hold/Resume, transfer, conference, etc.).
Calls involving supplementary services such as transcoding, DTMF-interworking, IVR, SIP-TLS, RSVP, STUN, RTP-SRTP conversion, or fax/modem features are not preserved in a failover.
Video streams are not preserved upon switchover, although the audio stream can be preserved.
Multiple HSRP groups per router are supported, but only a single HSRP group per physical interface.
Loopback addresses with HSRP are not supported, the SIP bind command must use the HSRP virtual IP address.
Configuration synchronization between the Active and Standby router is manual, there is no automation. Configuration changes must be made manually to both routers.

Hi
Yes its true.
Stateful failover is possible.
1) Box-to-box Active/Standby redundancy
2) Inbox Redundancy:
You also need to take care of additional license requirements for failover.
