Unparking does not work---VVX400

[shatty]

Using 15.5 with latest build on Debian. This problem is happening on all phones. 17 Polycom VVX400/410.
Parking a call to SP1-5 works. But when using the SAME phone to unpark, it doesnt work. It will display half of the PBX's IP address and beeps. Can unpark from a different phone on the system but never the phone that originally parked the call. New install. Cisco Meraki router. I checked the config in the phone under Utilites, Line Key config, and BLF, and it says : Label :SP 1, Address :SP1, Type: Automata which is correct. Any ideas? For some reason it looks like the system is only reporting back half the IP address to the phone. For example...instead of 192.168.1.24:5060, it says 68.1.24:5060 when trying to unpark.

I'm not seeing your phones on the list of supported phones.

It is supported. I always use these phones. Its a legacy phone but still works. I have many installs with these phones and this is the only install Im having a problem with.

So if this is the only install you are having problems with it sounds like something not 3CX related and rather something specific to the install. Firmware or network would be my guess.
