CTI Client with Outlook integration needed

Hi everybody,

I’m looking for a CTI client which integrates in Outlook 2010 and 2013 to start phone calls from Outlook contacts through the desk phone. I’m looking for a CTI client which communicates directly with the asterisk server through TAPI or else how.

It does not have to be freeware but it should not be too expensive. The main requirement however is that it works reliable and runs really stable.

Thanks and regards,
Markus
