Recently I was trying to implement an IP PBX for my company, but I stuck by the jitter issue.
I have a cisco 1760 router with a 10baset WIC-1ENET card, and a cisco2560G switch, data on vlan1 (native) , voice on vlan2. Already applied Qos on the router.
Everything went good at first, but when I was trying to download a big file from the internet, things happened.
Here's how I did, I made a call from a ip phone to a landline phone, then put the line onhold, landline phone user can hear the on hold music, then I started to download a big file from internet, the landline user will hear music became jitter.
Cant find a way to avoid it, any advice?
Thanks in advance.
