Dear Vlat, Thank you for your response!
In fact I just want to remove the 'Reason' header (Reason: SIP;cause=487;text=ORIGINATOR_CANCEL), not replace it, because the Philips/NEC does not support rfc3326 and even sents a 'Bad Request' if this line is in a header. At the start of the post I tried the remove_hf("Reason"), but the field is not deleted. I also tried in route[0]: if(is_present_hf("Reason")) { remove_hf("Reason"); } but the line is stil present in the response to the far end (Philips/Nec). So it looks like the remove_hf("Reason") does not work... (I of cause already read the parts in the textops cookbook) -- View this message in context: http://opensips-open-sip-server.1449251.n2.nabble.com/reason-headers-tp7137781p7150616.html Sent from the OpenSIPS - Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
