Nice tutorial! Im able to make outbound ISN call now. However, the prefix "**" corresponded to the default Call Pickup feature. I needed to disable it before I can use the dialing string suggested here. Also, like ENUM does this mean I need to open up or allow for Anonymous SIP call? [WM: You can make the triggering dial string whatever you like. Doesn't need to be **. Just adjust it in your outbound route. You shouldn't have to allow anonymous SIP calls for our setup to work. Adding the entries to extensions_override_freepbx.conf takes care of that.]

There was an error in the original article which has been corrected. Beginning dial strings with a single asterisk may conflict with certain FreePBX dial codes. So we’ve changed the single asterisk to two asterisks. The only change you need to make is in the outbound route dial pattern which now should be **|X.*X. with the trailing period. And, of course, to make calls, the syntax now looks like this: **1234*1061

Old news, but one of the best step-by-step tutorials I’ve seen on the subject!
