I just installed an outside 1a2 phone. Ran 25pr underground in conduit, installed a pipe to hold up an aluminun weatherproof enclosure with a Comdial 10 button phone inside. Also added a paging horn in the tree. The 1a2 can access the doorphone directly, it's conencted to a NuTone pbx, and the other way is through Asterisk by dialing the paging extension (33). Intercom is accomplished through Asterisk as well. Even got the diodes installed on the 66 blocks for the right ringing. Most important extension is buzzer not bell. I am glad that others use this fine phone system (1A2) for home use. It's my favorite for sure!
