Hi,
I have found the solution - my FACs were correctly enabled but you need to use the dpark-retrieval code (*0 in your case) to retrieve the call. If you try to pickup the call by dialing the Park-Slot number directly or using the park FAC then dialing the Park-Slot number, the CME will seize the FXS line and you will need to shut-no-shut the voice port.
Here's what I tested recently (keep in mind that my ANL ports are SCCP-controlled):
Situation 1:
- Parked external call using 79xx phone, park-slot assigned is 4701
- Took ANL phone off-hook, dialed 4701, heard 2 clicks, no audio, call still parked according to Park-Slot BLF
- Hung up ANL phone (hookflash does not work), no ringback, Park-Slot BLF goes out
- Took ANL phone off-hook again, was connected to parked call
- Line seized (cannot obtain dialtone either from flash, on-hook or other method), have to shut-no shut voice-port
Situation 2:
- Parked external call using 79xx phone, park-slot assigned is 4701
- Took ANL phone off-hook, dialed park FAC + 4701, heard 2 clicks, no audio, call still parked according to Park-Slot BLF
- Hung up ANL phone (hookflash does not work), no ringback, Park-Slot BLF goes out
- Took ANL phone off-hook again, was connected to parked call
- Line seized (cannot obtain dialtone either from flash, on-hook or other method), have to shut-no shut voice-port
Situation 3:
- Parked external call using 79xx phone, park-slot assigned is 4701
- Took ANL phone off-hook, dialed dpark-retrieve FAC then 4701, call connected and Park-Slot BLF goes out
- Hung up ANL phone, call disconnected normally
- Took ANL phone off-hook, dialtone.
Weird, isn't it?
