Daniel, I am not sure if this enough but here are the changes that need to be done to have a basic test bed working: *kamailio.cfg*: loadmodule "app_python3.so" modparam("app_python3", "load", "/etc/kamailio/kamailio.py") route { if (is_method("INVITE")) { python_exec("display_headers") } } *kamailio.py*: import KSR as KSR def mod_init(): KSR.xlog.xdbg("Python mod init.\n") return kamailio() class kamailio: def __init__(self): KSR.xlog.xdbg("kamailio.__init__\n") def child_init(self, _): return 0 def display_headers(self, _): KSR.xlog.xdbg("display_headers\n") header_name = "Geolocation" if KSR.hdr.is_present(header_name): i = 0 header_value = KSR.hdr.get_idx(header_name, i) while header_value: KSR.xlog.xdbg("Found header value: {0} for header {1} \n".format(header_value, header_name)) i += 1 header_value = KSR.hdr.get_idx(header_name, i) And your INVITE message then needs to have a Geolocation header. Something like: Geolocation: <cid:target123@atlanta.example.com> Of course the header name shouldn't matter as long as it is in the INVITE. Please let me know if this is enough or I should prepare something more. I am currently also evaluating lua script for the same purpose to see if the same error is observed.

I am not using Python module myself, although I helped adding Kemi support to it. It is not easy for me to create a testbed and try to reproduce. Maybe you can create a minimal config and a sipp scenario that can reproduce it. That could help the non-python developers to troubleshoot.
