Pap2 v2 5060/5061 one or the other work but not both

I have just recd a pap2 vonage unlocked off ebay…

I got it all connected up ulaw to asterisk…

port 1 5060
port 2 5061

when i run asterisk only port 1 light comes on and works, if i go into asterisk sip.conf and make a new statement bindport=5061 and reboot then 5061 works but the other goes offline… where do I get asterisk to recognize both 5060 and 5061 at the same time?

The pap looks like its working it comes up in the cli as port 10,000 weird… any tips of advice?
