I have a customer who needs three wireless phones for use in a building that has wireless access points. Due to the small number of phones, I was thinking of suggesting the call manager express running on a 3660 router. The 3660 router would also have a 2 FXO cards and the three FXO lines will be connected to the PBX as analog lines. The three extension on the PBX will be mapped directly to the 3 FXO lines on the router. Incoming calls from the PBX can be mapped directly to a wireless phones one-to-one by using PLAR. What about calls coming from the Wireless phones to the other PBX lines. Is it possible to map it out that the when the wireless phone A dials out it always uses FXO port 1 and when wireless phone B dials out it always uses FXO port 2, so that there is always a one to one mapping to a wireless phone and a PBX extesion. Thanks for your help. Any other suggestion are also welcome ?
