Hi All, I have installed 3cx call center edition with Skype connect VoIP gateway with few DID's and DID's are pointed to 3CX phone system Queues, All works fine most of the time. But everyday I am getting complaint from our agents says that, When they were talking to customer suddenly voice getting break and some time agents couldn't able to hear the customer voice. This issue I conformed listening the recorded audio file. Initially I thought it might be the Firewall / bandwidth issue. But we have 20 Mbps internet leased line and in 3cx Firewall checker also seems to be okay. And I am using the Cisco SPA 504g same network of the 3CX server. 3CX server on VMware and windows 7. So please let me know what may be the issue which causing the call drop / break. Many thanks, ramesh.
