We can only establish 1 call when trying to conference on the PRI from our TA908. It wont pick another channel on the PRi successfully and we are seeing a Forbidden 403 message in the debug. Any ideas on a solution. Thinking it has to be something easy. Thanks
Hello and thanks for posting.
If you attach or paste in a config (scrub it for any sensitive info like passwords and IPs), I can look at it. Sounds like it could be the tdm-group, voice grouped-trunk accept, or dial-plan that is causing the issue.
