Customer has SV9100 at Main site. POTS trunks and digital phones here.
At their Remote site, about 1/4 mile away, they have all IP phones. The IP phone and company LAN data travels on their own customer provided wireless connection, which has been working fine.

Now they want to add 2 or 3 wireless phones that key employees can carry with them throughout the plant.

Is the ML440 IP DECT phones and AP20 the way to go? They want full functionality of the desk phone, on their belt. If the employee's office desk phone gets a call, the wireless on their belt should also ring.

Is the AP20 a proprietary access point? Or can we use the company wireless LAN?

And just to make it interesting, they have several MLC client licenses with the app on their cell phones, but they won't use it! So, maybe a separate phone will make them think they have something useful. ???

Any experiences or suggestions? Thank you.
