wired network keeps going up and down from time to time

since I don’t use wireless so I don’t know if it’s the same for wireless network

anyways, problem solved by replacing network manager with wicd

one good thing about jaunty is that they finally include wicd in the universe repository

When there’s a new incoming call, asterisk-java will trigger a newChannelEvent, but there’s no information in this event that can be used for distinguish from which trunk this call is coming in.

By default the accountcode in this NewChannelEvent is null, which makes sense because the accountcode is used for billing, and no one, at least not many people, wants to record the charge of SIP trunk because that’s usually done by the SIP provider to which the trunk is registered to. But since the accountcode is null and useless here, maybe we can use it as an identifier to distinguish the incoming trunk, it may be not the smartest solution, but at least it’s a working one

The solution is pretty easy. Just open extensions_custom.conf and add
[ext-did-custom]
exten => <username from your sip provider>,1,Set(CDR(accountcode)=<some account>)
et voilà!

If you try to make a call from outside now, in this NewChannelEvent the accountcode is still null, but there will be a NewAccountCodeEvent and you can see that the accountcode is set in this event, and from the same uniqueid you can tell that both the NewChannelEvent and NewAccountCodeEvent belong to the same call.

*note: Remeber that you should never manually edit extensions_additional.conf, the file is generated by freepbx and all the changes you have done will be overrided the next time you apply some changes in freepbx
