Hello Everyone ! I am not sure if this error is relevant for this mailing list. My apologies if this is not the forum. I am trying to configure the Sangoma card, with the freetdm installation for Freeswitch. When I complete the wanpipe installation, and try wanrouter status, and wanrouter start I get the following: [root@bfree-server log]# wanrouter start Starting up device: wanpipe1 wanconfig: WAN device wanpipe1 driver load failed !! : ioctl(wanpipe1,ROUTER_SETUP) failed: : 22 - Invalid argument Wanpipe driver did not load properly Please check /var/log/wanrouter and /var/log/messages for errors Configuring interfaces: w1g1 w1g1: unknown interface: No such device done. ___________________________________________________________________ Can anyone help me understand why this is happening ? And how to resolve it. Thanks. Ravi
