How to add 'mobile' to Social Profiles

Hi,

I’d really like to add mobile phone and landline icons to the Social Profiles theme settings, so:

• they get displayed alongside the social icons with the same formatting
• on mobile, they show up at the top of the site on all pages

I’ve used your guide to add a ‘Mobile’ option to the Social Profiles:

function avia_add_custom_icon($icons) {
	$icons['mobile']	 = array( 'font' =>'entypo-fontello', 'icon' => 'ue8ac');
	return $icons;
}
add_filter('avf_default_icons','avia_add_custom_icon', 10, 1);

function avia_add_custom_social_icon($icons) {
	$icons['Mobile'] = 'mobile';
	return $icons;
}
add_filter('avf_social_icons_options','avia_add_custom_social_icon', 10, 1);

The problem I have is that the Social Profile field doesn’t seem capable of accepting
<a href=”tel:123456789″>123456789</a>

Can you advise how I can get this to work, or offer any suggestions for a different route to achieve the same thing?

Thanks!
