Is it possible to change the user portion of the URI in the contact header ?
I know you can change it when originating a call using sip_contact_user but there doesn't appear to be a way to change this on a per-profile basis so that it's also used in REGISTER and NOTIFY.
I want to hide it in order to obscure what I use for security - in much the same reason as you would disable or obscure the Server header in Apache HTTPD or the greeting from an SMTP server. Â Anywhere someone sees mod_sofia@ they know FreeSWITCH is at the other end and can refine an attack based on this.
I appreciate that FreeSWITCH is quite secure, and there aren't many known exploits for it - but every little helps to give a potential intruder less information to go on.
Hey Ross, If you search the archives there have been other questions like this but more from a "I don't want people to know we use FreeSWITCH or Open Source" point of view. Have a read of the valid replies why FS branding at some levels stays in and your options. I'd be proud to show off FS and just want to hide version/git numbers. Even if you did hide that you can still work out it's FreeSWITCH, but saying that sofia is an open source Nokia stack so it doesn't mean FreeSWITCH straight away. FreeSWITCH is respected and an extremely reliable product (plus all the other praise I'm too tired to write!) and should be honoured. It's saved us a fortune with our VoIP interconnects and we try to put money back into it (got a project starting soon re billing/LCR etc.).
