"callto" And "tel" Links For Skype And Other External Calling Applications


Recommended Posts

In a browser you can call using so called "callto" links, callto is used by Skype. For some reason navigate does not support this. It must be considered a bug since browsers, FF, Chrome and Edge (those are the ones I have tested) all can interpret a "callto" link in the proper way, it lauches Skype with the number in the "callto" link.

 

These browsers can also handle "tel" (which is used instead of "callto").

"Callto" is associated with Skype and "tel" with any calling application. FF, Chrome and Edge can handle these links, but the navigate command in UBS mess up these links by prefixing them with "http://". In my opinion this is a bug since navigate doesn't have the behavior like any other browser.


The format for "callto" links is this:

callto://+<the_number_incl_countrycode>

The format for "tel" links are:

tel://+<the_number_incl_countrycode


When trying to manually enter either a "callto" link or a "tel" link into the browser in UBS, it will add a http before (which in my opinion is a bug) i.e.:

http://callto//+<the_number_incl_countrycode>

(please note that also the colon after "callto" is deleted when it is prefixed with "http", it's the same behavior for "tel" links)


Has anyone solved how to use "callto" links and "tel" links?


Thanks!
