Hello All: We have install ser with mysql and radius support to use it as a proxy to another SIP server (voicepulse connect). We are going to authenticate the user with ser to record accounting data etc. After the user authenticate we need to send all PSTN traffic to the IP of the voicepulse gateway that use a username and password. Also we need to map incoming DID numbers with x user so the user can receive the phone call to the correct sip device. Any help will be greatly appreciated Thanks Cele
