Hi (Sorry my poor level of English) I am testing Libss7, i have two Asterisk connected to each other. The Asterisk is 1.6.1, Dahdi is 2.2.01 and libss7 is 1.0.2, the card is a Digium T4XXp with 4 E1. My topology is: In first E1, channels 1-2 for signaling, the remaining of the channels in this first E1 and others E1 are for data. This configuration seems to work correctly. I want to try another configuration in which a asterisk box is used only for signaling and multiple asterisk box are used for bearing data. Can I do this with Libss7? Or need to use Chan_ss? If I can do with Libss7, I need some clue,hint, apointment... to keep looking for. Thanks to all
