More ways to contact clients - telegram, whatsapp, etc.
For each phone number, i can configure a number of services - phone, telegram chat, telegram call, whatsapp call, etc.
System wide, i select which services we use with clients, and an associated icon and URL scheme. You would prepolulate with telegram, whats app, skype, the rest are up to us.
On the contact details tab, instead of just a phone icon, which uses the tel: URL shcheme, there are also iconds for skype, telegram, whatever else I set up.
Further, for services not using phone numbers for addressing, they can be listed as "Communications" rather than "PHone" but show up in the same panel for dialing in the details panel. As long as there is a URL scheme, i should be able to press 1 icon and dial or initiate a chat.
