Someone knows how can be configured 3cx 1.1.5 for Iphone such that it can call to people which use Eyebeam 1.5 for Windows? I follow the standard instructions from this site, and on the app main screen says "On Hook" and "10 voicemails"; which tell me that the softphone can connect with the SIP server. However, when I want to making calls, it says "Calling" and then "Not acceptable here". Any help is welcome. Thanks.
