NANO error

[NC4DC]

Can someone tell my what I am doing wrong.  I continue to get an error saying "NANO: Voip not supported".  I have a Kenwood TS-2000, and both RRC's are working fine inside my network on the TTL.  I have the cable for the Kenwood 9 pin data port to the COM2 on the radio RRC.  The control RRC SIP contact is the IP of the radio RRC and is also in the SIP contact of my phone.  Both RRC's are set to mode-4 and the baudrate is the same for all.  The SIP port, UDP audio, and UDP cmd are the same for all.  I have downloaded both the K and S app to my phone.  When I touch the "CALL" button on the phone I always get the error.  Any suggestions.........

Probably the phone is not supporting VoiP just as it says. This should be sorted out by Google Play already but maybe their database is not 100%. If you try with an other phone you will find out.
