Any got experience with these? I couldn't fint anything in any postings... it seems they have a h.323 on voip01.go2call.com and a sip on sip01.go2call.com I have tried to register with some of the same as I use for nikotel, but Asterisk does not want to register. I've tried to use both the user name (ingvald) and the PIN code 440.... as authentication. ---from sip.conf---- register => 440686267684:xxxxx@sip01.go2call.com [go2call] type=friend secret=XXXXX auth=md5 username=440686267684 authuser=ingvald fromuser=440686267684 host=sip01.go2call.com Any ideas, or where can I see all the options possible to pass to the server? -- With kind regards / Med vennlig hilsen Sjur Eivind Usken Hospitant i testnett gruppa Uninett AS +47 91772027
