Call waiting problem

[Mallox]

Hi everyone,

I need some help. Before I had an SPA-3102 and the FPL call waiting was working perfectly, But my ATA died and I had to change it.

So now I have a Grandstream HT-702 (FW 1.0.6.1) and since I installed it the call waiting fonction doesn't work anymore. I can switch the line, hear the other person, but he/she cannot hear me.

What I did:
tried to update to last FW (didn't fix the problem)
reset the config and follow to the letter the Fongo HT-701 device config pdf (dind't fix it)

Any suggestions?

With more troubleshooting with FW 1.0.6.1

If I configure the NAT to keep alive as per Fongo pdf and I try to take a second call it drop the first one and the I can't hear or talk to the second call...

if configure to the new NAT UPNP it does a similar problem than with previous FW, I can switch the line, I hear the other person, but they can't hear me...

So it seem to be a configuration problem... anyone know the right configuration?

FW 1.0.6.1

ALL default but:

NAT Traversal: UPNP
Transfer on Conference Hangup: Yes
Disable DTMF Negotiation: No

Enable Call Features: No
Preferred Vocoder:

choice 3: PCMA

FOUND THE SOLUTION

to any one with the same problem

ATA HT-702 configugation must be set to:
NAT Traversal: UPNP
all other configuration must be like the fongo pdf in the device section

And your router must be set to:
-UPnP Enable
-SIP ALG Disable
