We just went live on a 3CX system with Yealink phones. We have a mobile workforce, and we use overhead paging. On our old system, after the secretary answered an incoming call for Tom and paged something like, "Tom, line 1 please", if Tom did not pick up that line after 60 seconds, the user's phone would beep a special tone to remind the user to page Tom again. We call this "recall", which may or may not be accurate, but it's a feature our users need. Basically, if the line was on hold for more than 60 seconds, it would remind whoever put that call on hold. Is there a way to replicate this, or to achieve the same end result, with 3CX? We are using shared parking, so now we page, "Tom, line 1 please" with the understanding that Tom needs to pick up Park 1. Can we somehow have the server remind the user who put the caller into Park 1 if the caller is in Park 1 for more than 60 seconds? Thanks.
