[Freeswitch-users] Register problems

I have a LINKSYS SPA942 that refuses to register to my FreeSWITCH server. I have a FreeSWITCH log of the register transaction here: http://pastebin.freeswitch.org/14475 For comparison, I have my iSip phone which have no problem registering to my FreeSWITCH server: http://pastebin.freeswitch.org/14476 I hope anyone can give me a hint of why the Linksys phone is not registering. My FreeSWITCH server is not behind NAT. Ivan
