Project Description:
Hello, I have a problem with VoipSwitch from voiceserve.com or voipswitch.com

We need someone who has experience with Voipswitch for support and configuration.

Must have skill in managing Voipswitch
Please explain your experience with Voipswitch in PM.

I have a Voipswitch version 2.986.0.87
I have 2 terminations in Venezuela, one with the Gateway Grandstream GXW4108, and other with a Zycoo Zx50 - 4FXo ports. Both have the same problem.
I added them as gateway and as gatekeeper respectively.

Im using this router: Tplink TL-ER5120, and also a TPlink TL-WR642G
I can provide you remote access to everything.

If a person connected to my Voipswitch direct SIP with a Voip Phone dials, it works perfect,
but, when a person calls using the VoipBox, it have a problem: you can hear the other party, but the other party can't hear you.
Why is this happening? I tried many many times with many many options and nothing works.
I have this ports forwarding configuration:

1 10000-10200 ALL Enabled
2 9999 ALL Enabled
3 9000-9049 UDP Enabled
4 5060 ALL Enabled

Terminations are well configured, because when connecting with SIP trunks it make calls perfectly. The problem is when going thru the voipBox. It happens with both gateways.
Please write me if could solve this problem, and how much will cost

Please do not post if you dont have experience in voipswith, voip gateways configuration.

Thank you
