Resending with attachment. Hi Osmocom, I'm trying to integrate the FreeSwitch as my external MNCC in my test lab using split stack. Currently, I'm getting an error message on FreeSwitch SIP/2.0 400 Missing Contact Header. I'm little bit confused with the error and I don't know where to troubleshoot this. I've attached my osmo configurations and pcap trace for your reference. Hoping for your reply. Thank you.
