Hello,
I'm facing to some challenge in my learning process and using Kamalio as MS Teams
SBC,
the request I receive from MS Teams seems to be correct but I need to overwrite the
Original Domain, which is the FQDN of Kamailio itself, to another domain name:
INVITE sip:+15142144069@dev-sbc.openfabrik.com:5061;user=phone;transport=tls
SIP/2.0Record-Route:
<sip:155.138.140.233;r2=on;lr=on;ftag=3e2ca0c5d0da4335b121f205a6f20541>Record-Route:

rewrite to:

Take a look at UAC module:
https://www.kamailio.org/docs/modules/stable/modules/uac.html
In your case:
uac_replace_to_uri
You can also use replace_all within textops:

Hello Fred,
Thank you, that did replace the to_uri.
I'm now facing with another thing: "407 Proxy Authentication Required".
I already added the 3 MS Teams GW to trusted source in the FreeSwitch ACL:
But still getting this Proxy Authentication Required error.
Any tips for investigation is welcome.
Thanks,Victor
