Hi, We have moved to the above config a couple of weeks ago, and really liking the new-found stability I see in this configuration. Previously, we used to use Asterisk 1.6 + Chan_SS7 1.3, and was met with numerous "crashes" in high CPS situations. However, in this setup, the early media is giving us troubles. With the default config, no ring tone, no early media. When we put "prematureaudio=yes", still no sound. And, putting "progressinband=yes" makes Asterisk generate a ring tone, as is suggested by the note in the conf file. But, we would like to get the early media that we get from the Telco side, many of which are custom tones, like songs, music etc. Can someone please indicate what could be wrong in our setup?
