I have a bit of a Rube Goldberg setup, and surprisingly enough it is working with intermittent success. I was hoping someone might be able to give me a little help to make it more reliable.
My apartment is gated with no general code. This is unacceptable, since it requires me to answer the phone, and in this day and age is considered manual labor. To get around this, it calls my Google Voice number. I have the phone number for the door call box routing to my gizmo account, and from there forwarded to my asterisk box at home. Since I have a dynamic ip address I have the calls forwarded to door@.dyndns.org.
Yes, there are a lot of potential points of failure here, but I think it should be more reliable than what I am seeing. I have periods where it works, followed by periods of timeouts when registering:

So, if anyone is bored, and have some suggestions on where else to look, I’d appreciate the help
