Hello
I am trying to set ulaw on ss7 channel.
To do so i have set mulaw=1-15,17-31 in dahdi/system.conf
When i check dahdi show channel 8 i see Default law: ulaw , which is ok.
But when a call is established and i run core show channel DAHDI/8-1 i see :NativeFormats: (alaw) WriteFormat: alaw ReadFormat: alaw
In ISUP IAM Transmission Medium Requirement are set to 3.1 Khz Audio and Level 1 Information in User Service Information
is set to g711 ulaw.
How can i force asterisk to work with ulaw on dahdi channels?
Best regards
Yulian Oifa
