OpenSER - Troubleshooting: AVP
Problem: AVP created during the initial message is not available in “onreply_route[]“
Answer: By default AVP created during initial message is available in “failure_route[]” but not in “onreply_route[]”. To get the last a parameter in TM module must be enabled:
modparam("tm", "onreply_avp_mode", 1)
