Changing Codec on CISCO ATA for second call

I want to be able to use both phone ports on my cisco ata. when one call is up and active the second port will ring or dial out but as soon as connected to the other party I get fast busy. Im pretty sure I have to set a codec class so that the second call uses Codec g711ulaw. How do I make it do that. here is my current codec config:

LBR Codec: 3
AudioMode: 0x00150015
TxCodec: 3
RxCodec: 3
