Good afternoon forum.
I have a small problem with my Astaro and VOIP in that I am having what seems to be a common problem of "one-way audio".
Astaro Firmware version: 8.201
My VOIP Server sits on the LAN at 10.0.0.5
My Astaro is on the LAN on 10.0.0.1 and for example purposes, sits on my "clean" internet connection, the public IP is 123.456.789.001.
I also have a 2nd internet connection ("dirty") which sits on 147.258.369.001
I have 2 x Extensions configured in the PBX software, 101 and 102.
(note that the public IP addresses shown above are for EXAMPLE only and are not my real IP addresses!)
I have physically removed extension 102 from the local network and re-connected it on the internet (onto my "dirty" connection). I then re-configured the device to use the external IP address 123.456.789.001 and port-forwarded "VOIP Services" to the internal VOIP server using NAT on the Astaro box.
Note that the "VOIP Services" group is the default "VOIP Protocols" group provided by Astaro ... I have also added to this group a "VOIP Audio" service definition which is configured TCP/UDP 1:65535 → 10000:20000 (the 10,000 to 20,000 range is as per the RTP.conf of my VOIP solution).
The problem is that although the person on the "outside" using Extn 102 can hear the person on the "inside" using Extn 101, but NOT the other way around!
Have I missed something or configured it incorrectly somehow?
Although I have read pages and pages on Google about this problem, nothing seems to help, I think the problem may be Astaro, hence posting here!
MANY thanks for taking the time to read this, I hope that it is understandable but if you have any questions or need for more info, please ask!
Otherwise, I hope that someone can respond and help !!
