I need to know how good the quintum call relay SP is to recieving the calls and pass over to the recieving gateways, at the same time a billing needs to be attached to it, so we can have the CDR based on both recieving and sending IP. I heard that the quintum call relay standard is good, but the SP version has serious problems. Are you actually using the SP or the standard version?
Please considering the tasks we need to be done as mentioned above, please advise if the whether the quintum call relay is a good choice? if not what is?
