<br>
I have Kamailio connected to PSTN gateway.<br>
<br>
Sometimes gateway replies with "503 temporary unavailable". PSTN gateway adds a "reason" header with ISUP code.<br>
But according to RFC <a href="tel:3261" value="+333261" target="_blank">3261</a> kamailio doesn't forward 503 replies transparently. When 503 reply is received Kamailio replaces 503 with a 500 which is created from original request (build_res_buf_from_sip_req).<br>
I have tried append_hf from textops module, but it's not working with a locally generated replies.<br>
<br>
How can i copy Reason header from 503 to 500 ?<br>
<br>
<br>
I will appreciate your help with this situation.<br>
<br>
Best regards,<br>
Vitaliy Aleksandrov.<br>
