Hi All

I've used osmo-bsc in non standalone mode ie seperate components and all works fine voice and sms work as should. However when introducing. sip connector with asterisk the handsets will not make voice calls they just constantly respond network busy. I'm using osmo bts-trx with osmo-trx-lms on raspbian 10 below is Asterisk config. Any help would be appreciated.
