Hi all,
I’m using freedv in asterisk dahdi channel. I'm using two PC with two PCI
AEX800 connect over a PABX. In one PC i’m running freedv modulation and using
dahdi_monitor in other PC to get modulation data, push into freedv_rx it work
fine, demod snr ~ 20dB. But when i run demodulation in asterisk not get sync
and very low demod snr ~ 2dB. Anyone has any recomment for me?
Thanks alot.
