So, this device (presumably the phone) , if a remote device, has some kind of STUN or ALG in the picture. > sip:[email protected] > <sip:[email protected]:15060;x-sipX-privcontact=192.168.15.101> > 771 This device, presumably the ATA, does not have STUN or ALG, so it should be capable of receiving incoming calls. If that is not the case, could you please send me a network capture of the problem? You can initiate a network capture but from the shell of your sipXecs box with the following command: tcpdump -n -nn -s 0 -i any -w net.cap While you have tcpdump running, reboot your ATA and once fully up, try to call it. Once this is done Press ctrl-c to stop tcpdump and e-mail me directly net.cap along with a brief description of your observations. > > Thanks, > Max > > On Mon, Feb 22, 2010 at 1:05 PM, Robert Joly <[email protected]> wrote: > >> Robert, > >> > >> I removed the STUN configuration from the ATA and reset the device. > >> The behavior is the same. > > > > What about the Linksys router, any SIP ALG lurking in > there?
