Real World Advice on Hosted PBX Option

Hello,

I am looking for advice \ recommendations for a hosted PBX phone system, preferably one with an associated smart phone app that will allow our users to have thier DID \ extension numbers go straight to their smart phones and eliminate the need for desk phones.  
We are currently using a system from one provider, and have had consistent problems with calls not reaching end users, trouble transferring calls, etc., so am looking for options to make a move.  

Our environment is as follows: a single office building that currently houses four different companies.  The phone system would be used by one of the companies, who has approx 15 users in the building.  There are currently approx 35 users in the building total.  Internet connectivity is a 30 x 30 fiber connection, and there is a Cisco wireless LAN throughout the building split into three WLANs (one of them being the guest network and all of the users have their smart phones connected to the guest network).

It is certainly possible that some more fine tuning needs to be done on the WLAN side, and this is a relatively new area for me.  We have had some limited success in getting calls to reach some persons when they set the app on their phone to use wifi only for the connection, but the calls are still received inconsistently and when they do connect they are often "laggy", so again, I understand that this may be related to the infrastructure as well.  

Having said that, though, I would still be very interested to learn if anyone has any "real life" experience with a hosted system that they have been very pleased with?

Thanks very much,

Russ

Have you considered the Windows-based 3CX platform? I've worked with it on and off for a while now, and it certainly seems to work well. The 3CX softphone is quite feature-rich and has capabilities that IP deskphones can't match yet.

The latest version (v14) is designed to provide a hosted platform more or less out of the box, so there aren't any arcane procedures to endure before it will work a) properly, and b) at all.

However, a flaky WLAN will make even the most sophisticated VoIP system sound cheap and nasty, so that does need to be sorted before you can get good results from any VoIP solution.
