Re: [OpenSER-Users] fail to authenticate INVITE messages

Hello,

for INVITE you have to use pv_proxy_authorize("") http://www.openser.org/docs/modules/1.3.x/auth.html#AEN281

The problem is that the domain part for the URI of the user you want to authenticate does not match the value from the realm attribute of authorization header. Pasting the SIP message will help to give clear indications.

Cheers, Daniel

Hi all,

I'm trying to authenticate INVITE messages with OpenSER 1.3.0 (SIP Proxy + RTPPROXY) and LDAP module. Although REGISTER authentication works well, I cannot check user authorization for INVITE messages. I'm using an openser.cfg configuration template from sipwise (see an extract below).

pv_proxy_authorize() routine always returns false, even if my user is registered and authenticated through our OpenLDAP. Can you tell me what I'm doing wrong ?

Many thks,
