I have a hg4000 gsm gateway that I am trying to get working with asterisk and am having problems. Not much good with linux etc, so please bear with me.
I am told there are two ways to get calls on the gw to asterisk, one where it is requireing registration, the other which does not. The settings provoded for each case are as follows
If using registration
; GSM VOIP Gateway HG-4000
Now, I have configured sip trunk not using registration, so pretty much simply put in my details as follows in the outgoing settings
Incomming settings I have left blank for the moment, and registration striing is also balck.
With the above, I shoudl in theory be able to make an outbound call, but I am getting trunks are busy message.
Any help appreciated. I have managed to successfully register a sip trunk to a voip provider and can make incomming and outgoing calls okay, so i seem to have the basics right.
