A bit news (not sure it's right thread but)
We've done a FusionPBX (4) - VTigerCRM (7) connector.
As of now it's doing click2call functionality + popup on incoming call (if your office phone is ringing)
Used own fork of FusionPBX (based on 4.2), cause requires code change. But tried to do it as non-critical, as it possible.
Fork of FusionPBX - https://github.com/samael33/fusionpbx (need to use vtiger-connector branch)
Connector itself - https://github.com/samael33/vfusion
As of now not much documentation on it, but it's not final release, done mostly for internal use.
