Please log in for more thread options Hi If I got it right, some firewalls support SIP easily through STUN or UPnP, while others don't, requiring the use of fixed RTP ports and opening the ad hoc ports on the router. I noticed that some SIP devices, including the GrandStream GXP-2000 and the SJPhone softphone report back the type of NAT router that sits in front of the LAN where the device is sitting (in my case, "Port restricted cone"). Is there a stand-alone utility or web application that reports this information, so as to make it easier to deploy SIP devices? Thank you. | |||||||||||||||||||||||||

Please try miniSipServer which is a SIP server for windows. But it can be STUN server at the same time. > wrote:
