Hi Richard,

Any incoming 503 reply is converted by OpenSIPS to a 500 reply (as per RFC3261).

Hi,


we are getting 503 messages back but when this is stored on Homer as a 500. I'm not sure if its Opensips's sipcapture module or Homer doing the translation


This is the packet captured in sngrep in the sip box
