I have vtigercrm 5.2.1 installed and working fine with Elastix-2.0.3-i386-bin-15Nov2010. Click to dial works, and so do incoming screen pops, but only when the incoming call is from another local extension. Screen pops for incoming calls from a Zap trunk direct to an extension do not work. Incoming calls from a local extension to a ring group do not produce screen pops either. Incoming calls from local extensions always produce screen pops. I have tried just about every context that I can think lines @ approx 103-107 in AsteriskClass.php, including: from-internal default ext-group from-trunk from-internal-xfer from-pstn Any ideas? I'm going to try installing the latest SVN build of vtiger, but I think it's a context issue, or maybe a bug with the AsteriskClient.php script.
