Hello-- Looking for a solution. I'm using asterisk HEAD version, from a day or two ago. Trying to register with a Metaswitch voip server via sip. They gave me a userid, and a password. I plug it into a register command in sip.conf: register => 3074449999:pword@isp [isp] realm=voip.isp.net auth=3074449999#c491b58f6fd6da12691fa0de86fbbcc3@voip.isp.net type=peer context=workline host=voip.isp.net username=3074449999 md5secret=c491b58f6fd6da12691fa0de86fbbcc3 ; usereqphone=yes and the logs show: NOTICE[16299] chan_sip.c: Failed to authenticate on REGISTER to '<sip:3074449999@voip.isp.net>;tag=as11f194ab' I use md5sum to generate the md5secret... echo -n "3074449999:voip.isp.net:pword" | md5sum as advised in the wiki... What do you do with a SIP server that wants md5 authent? I've tried all sorts of permutations on this theme in the sip.conf file, I won't bore you with them here.... (Of course, I've modified all private info to protect the innocent... well, me, at least). Anybody can give me a pointer or two? murf -- Steve Murphy <murf@e-tools.com> Electronic Tools Company -------------- next part -------------- A non-text attachment was scrubbed...
