[turba] Adding SIP/VoIP contact field

Yup, and then add the field definition to config/attributes.php. Or  
you could use one of the existing phone fields, though I guess if it's  
a skype username you couldn't.

Not sure where you're seeing the contact displayed in IMP?

But for the rest, if you use a 'phone' field type for the new field,  
you can implement a "telephony/dial" registry method (see  
http://wiki.horde.org/CustomizeApis for how to implement API methods)  
that produces the dialing link.

You could write a similar form field type and varrenderer  
implementation for skype or sip, with similar API calls for  
customizable clicks (probably not needed for skype; if sip:// is a  
standard URL format then we wouldn't need it there either. The  
telephony call is customizable since difference installs are going to  
have different click-to-dial methods.

Sure, see if the above makes sense to you and let us know if you have  
further questions.
