[Serusers] Telco GW

Hello friends, question is simple and straight: what would you suggest as isdn pri telco gw for outside dialing from sip equipment ? We are experimenting with asterisk, works fine but misses radius accounting. We tried to do accounting on ser side but this does not correctly handle calls status, example: a call is routed from ser to asterisk, and from asterisk to the pstn. Invite and bye are recorded by ser in radius but if call is answered or not it does not make any difference, just an invite and a bye are logged. I'm I missing something or maybe the only way to go is "gw accounting" and "big money Cisco equipment" ? Please help, if you can ! :) -- Best regards, Alessio mailto:afoc@interconnessioni.it
