Thanks for your great ideas. Can someone describe a use case of ISUP over IP configuration. Is it possible for example to use the following configuration: - One SS7 switch with ISUP over IP capability connected by IP to a telco switch. - Many TDM Gateways with many E1/T1 links to a telco switch. The important question here are SCTP, M3UA and ISUP capable of controlling the calls between the telco switch and the client over the E1/T1 links without the need of any other information. Thanks again. Best Regards. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-ss7/attachments/20100705/521c1109/attachment.htm
