As far as I know I am using the standard configuration,
There is no indication that the router supports or not any sip:
activity. I bought it on 31 Jan 2006.

Is not port forwarding a Firewall service?
It has not been set up anywhere.

These are the results of all tests:

Linux 8.04 responds to calls with female voice, calls back when asked,
but does not echo any voice.
Linux 9.04 calls out, but no sound results when connected. Call back
rings the phone but no other sound.
Windows XP responds to calls with female voice and calls back ringing
the phone, speaks the message but my voice is not echoed.

I am grateful for your help and patience with me, I am somewhat computer
literate, but new with Linux., and command language is very new to me, I
need all the assistance available.

I will continue to try to get you the Windows reports.

Regards,

Emanuel
