I use to work for Tie...sounds like your company downsized...got rid of the recptionist...just stored the phone from x300...theres prob a call coverage key(s) on other exts...if there was a dss unit
then port 301 might need to have its type changed. We use to skip 301 when using a dss. found it did cause tramau. Keep in mind...if you do reconnect x300 and drop 301...that person will lose handsfree/ speaker phone function.
