Configure Polycom IP430 with DLink router DI-624

[Mohsaj]

Hi,

I am trying to connect a VOIP phone (Polycom IP 430)to my DI 624 router. I get connected and I am able to make a call but I am not able to hear the call going through or the other party who picks up. The called party is able to hear me very clearly. I configured using the Virtual Server in the Advanced Tab too but end up with the same result.

I tested the VOIP connection with a LinkSys WRT4GS and another NetGear router, it works perfectly. I face a problem with the DLink router only. Can anyone please help? Thanks. Mohsaj
