Hello All,
is there a way for freeswitch to convert receive response code to another code.
i would like for example to convert 3xx received code to 603 code.
Thanks. |

Kind of.
FreeSWITCH doesn’t expose low-level signalling anatomy on that level of granularity. You don’t handle individual SIP messages in the dial plan, right? You handle channel events and call flows. This is because FreeSWITCH generalises call events from all the signalling technologies it supports.
However, some innards of the Sofia SIP driver are exposed; it’s by no means an airtight abstraction. You can exert some control over what FreeSWITCH does in certain scenarios. But, thinking of them on the level of a SIP message is unproductive and fruitless. This question really operates on a different level.
But in terms of handling redirects per se:
https://freeswitch.org/confluence/display/FREESWITCH/Handling+SIP+Redirect
If you use ’sip_redirect_context’ to kick the call to a context which then contains:
<action application=“hangup” data=“CALL_REJECTED”/>
See this for more details:
https://freeswitch.org/confluence/display/FREESWITCH/Hangup+Cause+Code+Table
Thus, in a roundabout way, you can do it, but it doesn’t mean you can handle any SIP request or reply any way you want at that level of granularity.

HI Alex
Just to chime in with another solution here. I developed drachtio (https://drachtio.org/) as a solution to make it easy for developers coming from a web background to build sip apps. You can build both sip proxy and B2B apps. Doing things like changing headers is greatly simplified as well. If you want to learn more, feel free to join my slack channel to ask questions of me or the community at https://joinslack.jambonz.org
