I am having issues with the Page() command. When I add the line for example exten => 450,1,Page(SIP/451) it does page the over head SIP speaker (Cyberdata), but it asks for the conference pin number. Asterisk version is 13.7.0 and DAHDI is installed for the meetme timing. Any ideas why the page will not automatically join the conference?
You should check what the confbridge.conf file has inside. Try to set an empty pin there. Page uses confbridge to setup a conference with all the phones, so I guess it reads what default values are inside this file and asks for a pin. Try to modify it.
