FreePBX 220.127.116.11 with Asterisk version 18.104.22.168. Trying to get a ring group to include custom extensions. I've an extension 451 that is set up as a Other(Custom)Device in the extensions module and it's got the following in the "dial" field: SIP/'mytrunk'/'mycell' I've put extension 451 in the Ring group 601 and when I call the ring group 601 the caller hear's ringback but I never get a call delivered to 'mycell'. If I dial the extension direct, the call is successfully delivered to 'mycell'. I know in ring groups you can enter in the external Dial, but I really need to have the ring group & the Queue's dial an extension instead of an external number.
