Hello,

We've issues to get odoo 11 VoIP working with asterisk. We can make calls from odoo to SIP phones without problems, but we cannot make calls to odoo neither from a SIP phone or another odoo client. The browser is ringing but odoo sends the error "480 Temporarily Unavailable" when answering.

We've followed all guidelines including the following links.

• https://www.odoo.com/documentation/user/9.0/crm/leads/voip/setup.html

• https://sipjs.com/guides/server-configuration/asterisk/

• https://www.odoo.com/apps/modules/11.0/voip/

We're running latest odoo 11 and we've tried with both asterisk 13 and 15.

Does anyone actually got this to work completely and/or does any have a solution?
