SV8100 cannot ping gateway IP from router.

[AusieTiger]

Hi all, I setup a SV8100 to work with NEC ST450, all working fine locally using WIFI, tried external remote through WAN router, calls connected but "Mo speech path", ports forwarded: 5070 (UDP) to server IP (10-12-09), ports 10020- 10083 (UDP) to Gateway IP (84-26). Tried ping from router, found ping to server IP okay, ping failed to Gateway IP? What was missing ? Please help. Thank you all in advance.

I am not sure if a ping to the address in 84-26 actually works. Make sure that SIP ALG is turned off in your router. This sounds like the port forward to the 84-26 address has an issue. Those ports provide for the voice part of the communication.
