[asterisk-users] Monitoring SIP & Skype connections

[Myles Wakeham]

I have an Asterisk 1.4.2 server with 3 different SIP providers and 
Asterisk for Skype gateway installed.  Periodically the SIP providers go 
offline for some reason, or the Skype connection fails.

When this happens, I lose my SIP registration to the provider. 
Unfortunately I don't know this has happened until someone eventually 
contacts me to say, "I tried to call you but it didn't work".  This, of 
course, sends the wrong message to the caller and I have no way to 
determine if I'm using a reliable SIP provider or not as I have no 
statistical log of their uptime.

What I'm trying to find is how others monitor the uptime status of any 
external SIP providers or gateways that they use.  Are there tools or 
add-ons available for this that will email me when a SIP registration 
goes offline?

Any suggestions for this would be greatly appreciated.

Thanks
Myles
