SIP linphone account

Hello,

I’m looking help for Linphone account to Asterisk.

I have this error : Got SIP response 500 “Internal Server Error” back from 91.121.209.194:5060

My parameters are for chan sip :
Outcoming :
host=sip.linphone.org
username=aaaaa
secret=xxxxxx
type=peer
insecure=invite
fromuser=aaaaa
fromdomain=sip.linphone.org

Incoming :
user : aaaaa
secret = xxxxxx
aaaaa:xxxxxx@sip.linphone.org

What’s wrong ?

It’s for Trunk

Thanks
