Voice comes in but no voice goes out?

[nmadiratta]

Just wondering if anyone has any suggestions. I'm using 3CX v 3.1 I believe, it is the latest build on the web-site. I am connecting to webcall.ca for my VOIP Provider and everything seems to authenticate okay.

I can make/receive calls, and I can hear the other person but they cannot hear me. I'm using the 3CX Software Phone, latest version on the web-site. Just wondering if anyone has any ideas?

I have tested the headset and verified that it works, I can even see the level indicators go up so I know the headset is working. Any ideas? Am I doing something wrong?

make sure STUN is resolving your IP Address(you can see if theres any error message on server logs). Stun is number 1 cause of audio problems with Voip

Ahh okay. I will check in to that when I get home. Is there an STUN I could use?

 

[miraportuga]

The default 3cx uses should be enough, in some cases thoug(i had this problem) i had to go to Voip line configurations and below proxy and registrar i had to input a diferent STUN server to be used... try some of this list http://www.voip-info.org/wiki-STUN

Good evening

Good evening,

When you call internally from one internal extension to another can you hear voices both directions?

Is the extension you are calling from internal or external?

Have you bound the extension to the media server?

My thinking is that if you can send and recieve voice when you call another internal extension, there may be a firewall issue such as a port that needs to be opened.

Take care

And if it is a Port problem, and I think it is, this is the link to the Bible for Ports http://www.3cx.com/forums/the-portforwarding-faq-hope-this-gets-a-sticky-1697.html

Alright, I appreciate the help guys. I checked my router and had everything except for port 3478, and 9000-9003. I checked the STUN as well and that is resolving correctly in the server log.

The problem is still there. The weird thing is that when you speak in to the mic you can hear it play back on the headset, so I'm wondering if there may be some weird issue with the 3CX software? Or if my router is sending back incoming packets to me before they can get out of the network?

Also, I only have one ATA and one fax machine at the moment. I don't have any other extensions, although I will try setting up one after work on my laptop and see if that makes a difference.

Any other suggestions in the mean time?

Port 3478 must be opened in router for STUN.
Hope you restarts both router and 3cx after making these changes..

 

[nmadiratta]

I did open it, and I restarted the router, but I may have forgotten to restart 3CX. I will try this once I get home.

Good afternoon

Can you talk to other internal extension ok then?

You can use softphones for the other extensions if you currently only have one adapter.
