My basic STP solution allows for sharing signalling links across multiple asterisks, but for now each needs its own OPC. My largest need so far is 4 E1 for the same interconnect, and I can run 8E1 on a single box, so I'm for from actually needing to do it. This solution respects the minimum GPL standards (customers get the source), but I don't publish the source publicly. -- Atenciosamente, Marcelo Pacheco M2J Comunica??es e Inform?tica Fixo: (27)2222-8118 / (27)2233-2296 Vivo: (27)9964-5440 Claro: (27)9312-5319 MSN: marcelo at macp.eti.br E-mail: marcelo at m2j.com.br
