Actually with Telus Satellite I am sure you can use any companies home phone for the call display feature.
As Telus Satellite is really rebranded Bell Satellite - Bell Supports this feature (Relatives have Bell with Shaw home phone)
Here is a Bell FAQ:
Caller ID on your Bell Satellite TV
Now, when the phone rings while watching your favourite TV show, you can see who's calling without leaving your couch.
With the Call Display feature from Bell Satellite TV, the name and/or phone number of the caller appears on your television screen. You can decide if you want to answer the call or not. You can activate the Call Display option with your remote control by following these steps:
1. Press MENU
2. Select System Setup
3. Select Installation
4. Select Caller ID
5. Select Enable Caller ID
6. Then Save
Call Display is available on the following receiver models:
3100
4100
5100
5800
5900
6000
6100
3200
5200
9200
You must already subscribe to the Call Display service through your phone company and your receiver must be connected to the phone line for this feature to work.
If you can already order PPV, then you home phone is already hooked up to the system and maybe the steps above may work for you.
As Bell
typically doesn't provide home phone in pretty much everywhere Shaw phone is available there should be no reason in that any phone company will work with them and only Telus with Telus. Optik TV is different to Telus Satellite though. Either way you have to have Call Display subscribed to.
The Telus Satellite FAQ at the website does have some limited info available.
