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

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:
