I have a real problem offering Zoho to my customers as most use mobiles/iphone to currently contact us when technical problems occur on their servers systems or networks. They currently overload us with direct phone calls or urgent tagged emails ( often via smartphones) when they have a problem. 

In order to get them to migrate to using a support portal like Zoho they will only do so if it can be done from their smartphone in a really easy and simple way, else they will not bother and just phone us, rendering the Zoho facility rather useless.

What facilities eg: Iphone App, does the Zoho Support service/portal offer please

I have looked on your website and iphone apps but it does not look like you support this

regards

Howard
