Hello,
I haev purchased recently a 2port beronet card.
I installed and configured it easily with sip clients
I am trying to setup asterisk for fax receiving
I tried msdn -> iax -> iaxmodem and
misdn -> SIP-ATA -> fax pstn machine
The error i always get is
Dropping incompatible voice frame on mISDN/1-u1 of format slin since our native format has changed to alaw
any tips?
Are you using any particulair codecs? Fax only works with Ulaw, so any other codec would immediately destroy the use of fax.
i tried several codecs
The current configuration is
should i force only the usage of ulaw in [fax1]
in sip.conf?
Thank you

Yeah try that, it’s possible now that the Fax wants to get another codec then Ulaw.
