Phone loads 8.4.x use SCCPv17.
Loater phones loads use even newer versions of SCCP which will
experience the same problem documented in the defect.

8.3.x and earlier will use a version earlier thank 17 which IOS/CME/SRST
can parse.  Those versions may have other issues but should not suffer
from this specific problem.

Okay fine...now what is exactly meant by SCCP v17...is it any firmware
after 8.3 or 8.4?

CM7.0 shipped with phone load 8.4 which supported SCCPv17.

To avoid v17 you need to go earlier than that.

Check red text....which one should we believe:

 

CSCte08121 

 

Symptoms: Cisco IP phones running firmware that uses SCCP version 17
cannot register to SRST/CME-SRST, or will register but not obtain any
lines. 

 

Conditions: This symptom is observed on Cisco routers with Survivable
Remote Site Telephony (SRST) and Cisco IOS Release 15.0(1)XA. This is
the first image with SCCP version 17 support for SRST. 

 

Workaround: Download the IP phone firmware to a Cisco IOS release image
that does not use SCCP version 17. For Cisco 79x1/5/2 phones and Cisco
797x phones, this is 8.4 firmware. For Cisco 7937 phones, obtain a load
prior to 1.4(1).
