Workaround: To minimize the frequency of occurrence configure the sec.srtp.key.lifetime as long as possible.

•37437: When SRTP is used with both Authentication and Encryption enabled on SoundPoint IP 301, 501, 600 and 601 platforms, and three-way conferencing is enabled the phone will re-boot when a local conference is attempted.
