I used SPA9000 at home, and I don't find major issues.
I have a phone connecting to the FXS1 port (ext. 100). I am using other Android Softphone Media5 Fone to connect to SPA9000 (ext. 110, 111, 112, etc) for making outgoing calls.
The incoming call will ring the phone on FXS port without using AA.
I am not sure about your issue. Since my environment is home, it is not so important for internal calling. We just want to share the line for making external calls.
In your case, can you make outgoing call on 101 and 102 to external line ?? Do you experience one-way audio ?? |
