Its not the actual pts devices which cause problems. Those are happily 
created with any user name that's tried. It is the /dev/FS* links which 
won't create unless you are root. I'm not clear how udev can be used to 
make those creatable by someone like the freeswitch user. If you create 
a directory /dev/FS, make that writable by all, change FS to create the 
link as /dev/FS/*, and run as user freeswitch things work OK. However, 
/dev/FS is lost on reboot, because of the dynamic nature of /dev.
