I'm installing a Executech 616 and can not get dial tone. I've wired up set 10 and 11 to start. They are both 6614E phones and both pass their self test. I assume with out doing any programming that I should have dial tone on the intercom key and be able to dial from station 10 to station 11. I have read the install manual but still not sure why I don't have intercoms dial tone. I have battery on the handset and speaker and do get dtmf tones if I hit the buttons on the keypad. I try to log into programming and I hear the tones but it doesn't seem like I'm in programming. But I really don't know this system but do know telephoney. Can somebody tell me if the staytem is bad or if I'm totally missing something. Thanjsceverybody!
