I am having several problems with 3CX 1. No sound from PSTN gateway or Skype connect. but the person on the other line can hear me. 2. Incoming calls from Skype Connect PBX ring twice and then go to busy but outgoing calls work. 3. Cant tell if voice mail is working. (you should be able to get voicemail from the manager.) 4. After I added Skype as a VoIP provider STUN stopped working. 5. Can I have the digital receptionist do a "If you know your parties extension please dial it now" function? 6. Can i set the external ports and the internal ports to the same value because i have an extension that will travel in and out of Work network or will i have to set up a proxy? 7. Lastly the 3cx firewall checker is crap. it always fails of step 1a but when i run my own firewall checker with all services running there are no problems. The last one is just a comment but when/if you respond please state the number of the problem you are responding to to make it easy to read though. could all these problems be caused by a lack of ram? I only have 512 MB. i have never had this problem with other servers but i am more experienced in web and proxy servers.
