I use an app called Zoiper for clients. It is available for Android and Apple. Simply add the sip credentials and authenticate. Now your clients have their office phone on their smartphone. A great feature is that all contacts on their phone are automatically available as contacts on the app.
They will create a "white label" app for you for a fee, but I've never had an issue with any clients using the "off the shelf" version.
Thx
Has something changed about the format of numbers accepted. As, mentioned I've been using Zoiper for a while. Interestingly, recently I appear to be getting a lot of Proxy Authentication Required (407) in Zoiper. In fact I just tried (from home) a series of calls to my wife's number at work and it was hit or miss whether I got the 407 or whether the call went through with Zoiper. This was only with Zoiper and no Cloud Softphone running.

Just tried after seeing your message and it happened again. Proxy Authentication Required (407). The failure happens very fast - seems like it's trying to contact voipo servers which reject the authentication. Not sure what kind of information I'd provide in the ticket to support (it's never gets so far as a call being logged in my "history"). Then I dial again and it works - the first time was from the contacts. So I thought maybe the format was different - but what I see in the call logs of my app is exactly the same format. I'm sure this is one of those things which is frustrating for support to get to the bottom of with minimal information. All I know that in the past with the same app I never had this kind of issue, which was the reason for my anything change query. To me this is low priority as I use it more out of geek interest than having a practical need for it.
