SUS means suspend, till a resume (RES). They both originate from a line. This is normally by flash calls, instead of hang up. Suspend the entire trunk path, to allow a third party call or place on hold (to be brought on line). Resume the call once established. -----Original Message----- From: leonimar cape [mailto:leo_mac_ph@xxxxxxxxx] Sent: Tuesday, February 28, 2006 5:18 PM To: asterisk-ss7@xxxxxxxxxxxxxxxx Subject: chan_ss7 Hi Group, I want to asked if someone has successfully interconnected asterisk to a telco switch via SS7 using the chan_ss7? I was able set-up it successfully and interconnect it with a DMS Nortel switch. Also the quality is indeed perfect. But may issue is on the billing (CDR). In a call set up wherein the caller is on the asterisk side and the called party is on the DMS side, my circuit is not being release even though the called party already hungs-up the phone. I know that SUS will be send by the DMS to the asterisk, but SUS has not been included yet so it seems that asterisk dont know that to do next. Circuit is only being release if the calling party hungs-up the phone. Also, another issue that I have notice is that there is no ring back tone receive by the caller. This is only on a call setup where the caller is on the DMS side and the called party is on the asterisk side. I try to apply the RBT patch posted on the voip-info but it wasnt successfull. Any help and suggestion will be greatly appreciated. Thanks in advance. Leonimar Cape __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
