Telus Employee's, ??? Regarding "Push To talk" Service

Just a few ??? regarding the "Push To Talk" Service from Telus.

1.If im a subscriber to "Push To Talk" service and have the required phone, will i be able to communicate with some one else using a regular PCS phone that does not have the Push To Talk service?(using the 2 way radio option)

2. With "Push To Talk" Service can i communicate with Telus's Mike Network users?

3.Can "Push To Talk" users communicate with Nextel customers in the USA?

Any additional info regarding this service would be apprecaited. Thanks

You can only push to talk to others using the same service provider and it has to be a PCS PTT phone. Even though "MIKES" are Telus , they use a complete different system than the PCS phones. You cannot PTT a MIKE nor Nextel. You could use a Telus "MIKE" to communicate with Nextel.
