Need input on network config for VoIP
Asked by brainbolt in Networking Hardware, IP Telephony, Network Management
I'm considering implementing a VoIP system (like PBXtra, Switchvox, 3cx, etc), but need to address an issue with my network (See the attach pic for the layout).
My VPN between my two sites traverses the public network. I cant do anything about that because my branch office is in a rural area with very limited isp options. Baseline performance between the two sites seems acceptable (Latency: ~35ms ping time between servers; Bandwidth: 500+kbps throughput while my other applications are active over the VPN), but whenever a machine within my network generates web traffic by browsing a site, or downloading a file, the latency between the two sites spikes up to 300-400ms, and stays there until the transfer is complete.
Now, I know that there is no QoS on the public network, and when my VoIP data packets get out there, the routers in between aren't going to treat them any differently then your data packets for this website, and its a first come, first served scenario. But considering that the problems I am experiencing seem to be occurring when traffic is generated from WITHIN my network, is it reasonable to expect that I could address the issue by implementing QoS?Start Free Trial
