[asterisk-users] Early Media configuration doesn't seem to be working

[Maximilian Grobecker]

Hi,

on a similar setup I set in sip.conf:

prematuremedia=no
progressinband=never

in the peers configuration.
With this config you tell Asterisk not to handle inband information at
all. But: Maybe you won't get any inband "error messages" also.
