Calls made with 3cxphone result in a strange code being entered in the call log, rather than the number itself. Further, clicking on call from the call log doesn't work on these codes.
@flavor8: Please provide more details on what your setup is. Who's your SIP provider? Are you going through a sip account manager like sipsorcery or pbxes.org? Are you attempting to dial out directly from 3CXPhone? What phone are you using? What version of Android are you using?
I am new to 3CX but I have everything working but my incoming caller ID also. I came across this post and I can give you more details on my phone and see if we can't get this resolved. I have included a link to a screen shot of my phone showing my incoming test calls and my one outgoing test call to the local weather. As you can see, it only shows characters so I never know who's calling. I am running the original Droid with Android 2.2.1 on it on the Bugless Beast 0.6 ROM. I have 3CX 1.2.9 installed. http://dl.dropbox.com/u/2114546/screenshot.jpg
