Hi all, I've got a problem with my FXO cards. I've configured them to give a service to people on PSTN network, to call the lines connected to my Asterisk by a digium fxo card, and dial my VoIP network numbers. PSTN -> Asterisk -> SIP Client The problem is when a call is made by a user from PSTN network and, after talking or not, hanging up, the line is not hanged up by asterisk. But, sometimes, it is. I'd appreciate any help about this. Kaveh __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
