Hi All!
Im experiencing a little strange problem.
Im having problem to speak to other people in my network. When I receive the call in the Express Talk the caller cant hear me. Both of us are using Express Talk.
I can hear but the other side cant.
But it's a little strange cause when calling to outside of network like calling to PSTN phone number it works well.
The problem is when we are trying to talk to each other inside the private SIP network.
I am using the VoIPCheap SIP service.
The reason for strange is because I already get sucess on talking inside the network with other friend of mine.
I don't know what kind of problem it can be.
Anyone can help me?
Thank you
