External phone one way audio.


I can hear the phone call me and hear them on the phone but they cannnot hear me. Any idea? The external IP has all ports opened.

cgashlin01,

Do you have a PEC [Processor Expansion Card] in your system? If so it will need a unique external IP address as well or you will have audio issues.

Thanks,

Yes we have one.

[cgashlin01]

This is the only 5320 we have that is external the others are not and they work fine.

[cgashlin01]

Not sure if we have PEC where do I change we have HX Expansion

cgashlin01,

Alright if you have one then you need to put the second public IP address under it IP Connection.

System > Devices and Feature Codes > IP Connections > P6001 [Default]> NAT IP Address: This is where the second Public IP Address would go.

Then you would need to create a Route from the public to the local IP address of the PEC.

If you don't remember what the IP Address of the PEC is then you can look here.

System > IP Settings > Static Processor Expansion Module IP Address: This is the local IP address of the PEC.

Thanks,

[cgashlin01]

yeah I checked that and nothing is misconfigured.

cgashlin01,

So are you saying that you have a PEC and it is configured properly. Did you add the new public IP Address to the P6001 and setup a route and then test?

Thanks,

It is only affecting the 5320 phone.

Now me coming from a background of Asterisk and SIP I must ask..

Is there any type of STUN server input anywhere?

The remote location need any ports open?

So when I call that phone extension the phone rings. THe person picks up and I can hear them but they cannot hear me.

[cgashlin01]

I figured it out. I had to enable NAT in the 5000 for that particular phone.
