This is completely my own work, although its heavily derived from the default settings, a little inspiration from the freeswitch email list, pouring over the freeswitch doco, and copious trial+error.
Note: I havent factored in anything but blind parking and i dont use the orbit+park button in Snom. I just use BLF.
I recommend you disable (Enabled: False) the provided settings for your future reference.
Smooshing in to one extension was just mind bending, so it results in 4 extensions which are hopefully easy enough to understand and customize.
Once the destination number is found to match 59XX, the Referred-By and park_uuid are used to determine what the call is doing.
Referred-By will have something in it, if the call is being blind transferred in to parking. Otherwise the extension is trying to call in to it (i.e. pick up a call)
If a park uuid is found, that means that there is a call in the parking lot slot.
I also only set the parking lot variables if a call is going to go into the lot, which differs from the default configuration.
Here is 450 which just sets variables. For reference the parking_uuid line in full is:
I found that regexes in FusionPBX really really dont like quotes or gt's and lt's. Perhaps they arent being escaped properly when stored? i ended up just using dot's. The above regex could definitely be simplified, but i prefer my regexes to be as specific as possible to avoid side effects.
451 immediately transfers calls back to the referrer if the parking lot is in use
455 is where the callerid is retrieved and sent back to the extension trying to pick up the park. This example is snom specific - so you will need to work out what headers your extensions want to see and make changes as needed.
This is the extension that you will want to customize to suit your phones.
The magic is that the uuid_getvar allows us to pull variables out of any active channel - such as the channel in the parking lot! So with the uuid from the parking lot, I grabbed the caller_id_number and shoved it in a header for the extension retrieving the parked call. Having sip-cid-in-1xx=false eliminates having duplicate headers sent to the retrieving extension - although Snom's ignore it, i think its better to just have one header.
460 is where the call is either parked of retrieved depending if a Referred-By header is present
Breaks in the dial plan are very mind bending, so having separate extensions definitely make understanding and debugging much easier.
