Hi @lokesh426
Please ensure to add "tel:" as a special link prefix in com.day.cq.rewriter.linkchecker.impl.LinkCheckerImpl OSGi configuration. This will ensure the tel link is not removed from the page.

And yes, you need to update the XSS protection to allow any special chars for any attributes you want.
Thanks!
