[Spce-user] Error on ROUTE_OUTBOUND, REPLY_ROUTE_STD and REPLY_ROUTE_NAT

[Andrew Pogrebennyk]

Hello Raúl,

hm, I was specifically testing this not to happen. The exclude_hf_value
is executed in ROUTE_OUTBOUND and record_route() right after that, so I
don't understand how that could have happened. The lump error occurs if
we execute msg_apply_changes() after record_route().

Could you please provide me the kamailio-proxy.log for the complete
call? Before that you may set debug 2:
ngcp-kamctl proxy fifo debug 2
Also please make sure that you are not running with
proxy.cfg.customtt.tt2 from an older version.

Regards,
Andrew
