latest version is 2.1.14-507.
Regression from 2.1.15 to 2.1.14 is not recommended. It usually works but it isn't 100%. If you want to try it do this...
save the file /home/e-smith/db/selintra-work somewhere (use the -a switch).
rpm -e selintra-sail
rpm -e smeserver-asterisk
rpm -e smeserver-asterisk-zappri
rm -rf /lib/modules/{uname}/extra
Install 2.1.14
copy your saved file back to /home/e-smith/selintra-work
Immediately log on the the system (server-manager) and do a commit.
Do
/etc/init.d/asterisk stop
/etc/init.d/asterisk start
Now go and do PCI card discovery
stop asterisk with the STOP button in PCI
start asterisk with the START button in PCI
You may be lucky.

Best
