SoftKeySets fails with chan_sccp-b and ami interface prior to chan_sccp_b revision 11048.
Check the version with the installer, and subsequently to ensure that do not get exception by using old interface for this method with earlier versions of chan_sccp_b (including the current release).
Thanks to @dkgroot for recommending and @rofferman for reporting.
