I have a 3com sip phone that I can't seem to get correctly setup for * I set the identity of the phone to 5kevin2 I set the password on the phone to 222 (not the admin pw to change the phone's settings, but the pw it is supposed to send to the sip server) I set the sip server to my asterisk servers ip. If I don't add anything to the sip.conf file for the phone, I can dial internal extentions, but when I try to add entries for it to the sip.conf file, it gives this error : Jun 2 14:07:44 NOTICE[-1116451920]: chan_sip.c:6642 handle_request: Registration from '<sip:5kevin2@asterisk.huntbrothers.com>' failed for '209.16.88.183' Jun 2 14:07:57 NOTICE[-1116451920]: chan_sip.c:6334 handle_request: Failed to authenticate user <sip:5kevin2@asterisk.huntbrothers.com>;tag=43325296 Jun 2 14:07:58 NOTICE[-1116451920]: chan_sip.c:6334 handle_request: Failed to authenticate user <sip:5kevin2@asterisk.huntbrothers.com>;tag=43325296 Entries I added to sip.conf [5kevin2] host=dynamic type=friend username=5kevin2 secret=222 If I remove the above entries, and do a sip reload, then the phone can call internal extentions again. Am I missing something obvious ? If anyone has gotten these working, can you send me the sip.conf entries and the step by step for the phone setup itself? W. Kevin Hunt CCIE #11841
