    Going all wireless? Plan to quadruple your helpdesk staff. – generalnetworkerror Apr 15 '15 at 08:09
  • Why exactly do you think we will have more issues? – Weaam Apr 15 '15 at 08:53

    See the answers in the possible duplicate of [Is a wireless only network (for end users) a viable option?](http://networkengineering.stackexchange.com/questions/1014/is-a-wireless-only-network-for-end-users-a-viable-option) – generalnetworkerror Apr 15 '15 at 09:06
  • Thanks, I already read these answers, this is not what I am looking for, my question specific regarding the VoIP over wireless. – Weaam Apr 15 '15 at 10:26
  • You might consider using all softphones via your laptop which connect back to a central provider. There are several manufacturers which will let you use softphones in lieu of a physical phone. – James Shewey Apr 16 '15 at 05:45

Recommendations on which manufacturer to use are off-topic here. But I can tell you from experience that you can reliably do VoWLAN.

But the performance of the wireless network is more critical when you're using VoIP. You will need a denser AP deployment than for just data. You need to make sure they survey takes VoIP into account. Pay close attention to AP placement and expected user density.

You will also spend more time testing and tweaking your clients (wireless phones, etc), especially if you're using phones from a different manufacturer.
