Hello,
We are doing SIP Termination and have no need for any voice solutions built into the router. Rather we have our own SIP Proxy that needs to talk to carriers. We need the cisco to configure our IP Block but we are just looking to use bandwidth to send our traffic out.... Well we noticed that when we run only 100 channels we were getting bad voice quality. I noticed that the router CPU was running at 100% while memory and bandwidth were still rather low.
Is there a setting to help with this? Are we in need of a different device? I have figured out that the SIP Signalling is not the issue and that is seems the load is created due to the media RTP packets that need to communicate back and forth with our carriers.
We want to handle about 20,000 channels atleast as on our private network this is no issue currently because we send our traffic from our switch to the carrier thus bypassing our router. But now that we are testing public termination ourselves we were expecting to run about 1200-1500 lines of G.711 through the Cisco2801 figuring that would be about 80Mbps on a 100Mbps rated router.
Any help would be greatly appreciated.
Thx
Erik
