Here is yet another problem with OBi100, 1.2.1 (Build: 2384). This time it is with STUN implementation.
I need OBi to send SIP requests with SDP containing WAN (not LAN) address. In order to do so I have to configure it in "Service Providers | ITSP Profile X | General" page and set followed options:
STUNEnable - enable
STUNServer - host name of STUN server
I tried to use public STUN servers:
stun.ideasip.com
stun.counterpath.com
Both servers are reliable and work very well with other SIP clients.
Now, when I set OBi100 to send WAN IP, more often then not when I dial OBi will pause for 40 sec and then it sends requests with SDP, containing LAN (not WAN) IP. Which makes call impossible, of course - there is no audio... Sometimes it gets WAN IP and uses it immediately to make a call with proper WAN IP. Similar scenario happens when I receive calls...
The current STUN support implementation is completely unreliable. Please fix it ASAP.
Thank you.
BTW, how often do you think OBi changes its WAN address? Thus, why OBi has problem with WAN IP resolution 3 times form may be every 4-5 attempts?
