After searching the forum for my issue and ticking and unticking countless options I am now posting to find sme hopeful answer. Server that the PBX is located on is P4 2.8 ghz 2 gig RAM Dell 1U server. I have a Linksys Dual WAN VPN router RV082. Internet connection is a 10mb by 2mb connection and speed test come back 1 ms and 0 packet loss on Myspeed. There is a switch in between the router and PBX BUT I have switched them out to see if this was the issue at hand. Internally all my calls sound good and everything works as it should. I use OpenVPN for our employees to connect to our network then use the phone system through this. When I was running Trxibox(Asterisk 1.4.x) everything was fine for the remote callers. Now I have huge delays when my remote caller sends or receives calls to clients and its hurting the quality of our client conversations which are very important. I have disabled PBX DELIVERS AUDIO option with no luck and also tried with/without reinvite for xfer issue. No luck whatsoever. The logs bring no error and I have disabled and reconfigured our QoS to see if that was the issue at hand. The internal phones are Snom 360's and the remote phone is Bria. I also tried the 3cx softphone with no luck. The remote party that I testing with has a 25 MB by 2 MB connection and test on it came back fine, not to mention they used Bria with asterisk fine. Any help would be appreciated.
