I have a sip server that i remote users connected to. I have managed to get my trunks working properly. also internal users fine but external users are not working i get failed login due to interworking suspect this is because it is connecting to the sip server on the router as i get the same error when i turn off my astrix server. does any one know how to do true pass thorought on this router ?
