FreeSWITCH - Retain Valet Park Caller ID and add to SIP header (Simple Project) -- 2

Looking for someone experienced with freeswitch/lua and valet call parking. We need to send a sip_ph_P-Asserted-Identity header but it needs to match the caller ID for the call (keep in mind, inbound and outbound calls need to be differentiated). I already have a small but buggy "solution" that needs to be tweaked.

We keep the CID info in freeswitch hash database and collect the data when the parked call is retreived.
