Hello,
the second packet in the trace has \0 in the To header. Likely the endpoints is changing the From/To headers and restoring them with uac module is no longer working. Either don't auto-restore them or use uac with dialog module to store the the values. Kamailio 4.4 or newer should have a better detection of this case.
