Hello guys... I have a SPA400 gateway setup with the 3CX system. Everything works fine with the SPA942 phones but I cant get any audiofrom a ATA SPA3102 when calling from the POTS phone linked to it. The weird thing is that everything is ok the other way around ( When an extension or an external caller calls the SPA3102 ). The problem is only when SPA3102 calls internal extensions or external callees. Audio is NO GO on any side. I have searched trough various forums and tried all setup provided by the tutorials but nothing will do... Updated firmware, still nothing... Switched device, negative... Running V8 of the 3CX phone system. I have 3 years experience with VOIP in general and I installed over 10 Cisco SPA systems. Anyone can help me out with the SPA3102 ? It's gotta be sumptin with codecs or packets !!? Keep in mind I HAVE TRIED EVERYTHING FOUND ON THIS FORUM AND FROM THE 3CX WEBSITE. Thx guys !!
