I am trying to register asterisk as sip client with a sip provider. I tried both
register => [user]@[domain]/[password]
register => [user]:[password]@[domain]/[user]
but I keep getting the “Failed to authenticate on register” error. Credentials work fine when registering x-lite, so do outbound calls via asterisk.
I read about an “auth” vs auth issue with my provider (qsc, german thing). All posts for that are from 2005 so this might not be acute anymore.
How should I best investigate? Must I packet sniff? Is there a well known patch or am I just missing something very basic?
Thanks for pointing me in the right directions,
