I have configurd an extrnal lie using FXO GW (IPGear Claro GW).
When a I call to the PSTN line the IVM IVR is answering ask me to enter the ext' number that I want, after entering the ext number the ext ring (the ext is an ATA). but there is one way voice.
They can hear me but I can not hear them.
The GW an the Axon are on public IP the ext as private IP in the same LAN as the Axon (meaning the Axon and the ATA as the same public IP.
IF the EXT' is a softphone then I have 2 way voice and everything is ok.
Dose any one have an idiea what should I do.
