I have 3 SIP trunks with Broadvox, connected to a Linksys router. I am able to get the SIP trunks to register after a reboot, and when I make a call in, it rings and is picked up by voicemail.
However, after about a minute and 20 seconds, all 3 channels fall out of service. I can't get them back unless I reboot again, and then they fall back out of service. But it works for the first minute or so.
Here is part of the log while the call doesn't come in after a minute.
