Hi, I've managed to connect teams using FS, now I´m trying to implement call hold and call transfer. Teams use an unusual way for hold, it transfers the call. In the refer I can see the refer-to pointing to an url without a request uri user REFER-TO: <sip:sip.pstnhub.microsoft.com:5061 ;transport=tls;x-m=8:orgid:e83c0390-43cb-4c40-8d09-8a972709235b;x-t=9c36cf22-e6e8-4792-b823-873069b82489> How can I bridge a call to an URI without a request uri user? I tried sofia/gateway/ms1/ (without passing a user). I tried <action application="export" data="nolocal:sip_invite_req_uri=$1;$2"/> where $1 is the domain and $2 are the invite parameters but no success. Did anyone have success with TEAMS and call hold, call transfer? Thanks Flavio E Goncalves
