Hi, I am happy to announce, that the isdngw reached beta state, thus I want to encourage everyone interested in testing the PSTN gateway. isdngw is a PSTN2SIP and SIP2PSTN gateway included in SEMS. It runs on Linux and requires only a supported ISDN card (BRI or PRI). A new site for isdngw was launched, too. Find installation instructions and a list of supported cards there: http://www.iptel.org/isdngw Any feedback, may it be bug reports, information on ISDN controllers, any other comments or success stories ;-) are very much appreciated. Regards, Uli.
