Is it possible add new item in sip message header?
Hi All, We run a mobile app to *register* FreeSWITCH 1.6.20 via sip. This app will check value of server field in message header but the packet sent from FreeSWITCH doesn't have this field. We would like to know is it possible to add filed "Server" to message header by adjusting FreeSWITCH configuration? We tried this by adjusting dialplan ( https://freeswitch.org/confluence/display/FREESWITCH/Sofia+SIP+Stack) <action application="set"><![CDATA[sip_h_Server=xxxxxx]]></action> it works in invite stage, but can not work in register stage. The app checks the filed "Server" in register stage. Thanks in advance. -- Sincerely Albert Hsueh System Engineer Cloudpe Corporation 02-8712 5955 ext. 831 www.cloudpe.com
Any specific reason the app needs to check that header? It couldn't be considered secure since anyone could insert that header. It's similar to the user-agent which is set in the sofia profile, if implemented it'd likely be implemented in the same way which'd mean a small change to the mod_sofia code. I'd file a Jira.

Hi Thanks for reply. The app is for school. We think the developer wish this mobile app only connect to specific sip server so they do this kind of check. Sincerley Albert Steven Ayre <steveayre@gmail.com> 於 2018年10月6日 週六 上午3:33寫道：

That's my point though, anyone can put any value there they like (not in FS without a code change but you could in a SIP proxy or custom UA). The only way to limit it to a specific server securely would be via some kind of authentication or encryption. On Mon, 8 Oct 2018 at 15:51, 薛光宏 <albert.hsueh@cloudigit.com> wrote:

There is no way to do this without code modification to add this feature.
