Todd, Provider is IIS Group. Phones are Grandstream GXP2000. Firmware is 1.2.2.26. Router is a DD-WRT v24. The download link for the sipviewer .jar file found at http://wiki.sipfoundry.org/display/sipXecs/Display+SIP+message+flow+using+Sipviewer does not work unfortunately so I am unable to use it.
As Tony suggested in the previous post, my provider is not making request to 5080 but rather 5060. However I am forwarding requests to 5060 to 5080 through my router. Could this be my problem most likely?
