Installing the telephone line is part of the standard installation, it has been since we started doing DBS installations all the way back to 1994.
Directv used to enforce this rule very heavly until around 1999 when they started slacking off on it, and Dish didn't start until around 2003 when they came out with Dual Tuner receivers that penalized the customer for not connecting it up.
Both Directv and DISH Network have asked the dealers and installers nicely over the years to start connecting them up, but nouthing has ever worked!
With Dish its simple, connect the phone line or try to explain to the customer that they are going to pay an extra $5/mo. Most installers don't want to risk loosing the entire Job and just hook up the phone lines.
With Directv, hook it up or get a $5 reduction per receiver on your pay!
Sure the installers do not like it, but they are the only point of actual contact for the customers.
The installers got a choice, do it for Free or charge the customer!
I know alot of guys who will go out and do a standard DBS install and come back with an additional $200 they made from Extras they charged the customer for additional items like phone lines, surge protectors, television calibration and even computer networking.
If you sell it right you can get the extra money, but it does require alot of effort. Its like I remember the sales pitch for selling panamax surge protectors....
The first thing you do when you walk in a customers home is ask them where their surge protector is. When they say they do not have one you "let" the customer use yours for the duration of the installation as your hooking up your equipment. At the end of the install, you ask the customer if they would like to purchase the surge protector and when they say NO, you then pull out this stamp that says they are "Declining" the warranty and then you disconnect the surge protector from the satellite receiver and make the customer plug it in themselves saying you will not plug it in because you will not be responcible for connecting the receiver without the surge protector.
About 80% of the time you sold a surge protector!
The fact of the matter is that a typical installer doesn't have time for games, they want to hurry up and get the Job done so they can get to their next one.
