I'm in a unique spot. My company is the local CO, a hosted provider, an IT management company AND the ISP. Most of the time, call quality issues are my fault one way or the other, unless I can prove the problem lies outside my network.

The biggest problem we see with other people's networks is LAN settings that don't disable SIP ALG or allowing the port re-mapping tendencies of some firewalls.

Sometimes the thoughts in my head get so bored, they go for a stroll through my mouth. This is rarely a good thing.
