Rohit, You may be right, may be driven by configuration or may be because the client didn't indicate the T38 capability its switching automatically to G711 Mode.

Shanbhag; Neranza Bundova; [email protected] Subject: RE: Broadsoft FAX problem Hi If I understand it correctly, Somesh is suggesting addition of T38 media stream in offer from the endpoint whereas Neranza's query is how to make Broadsoft initiate T.38 fax instead of Pass-Through on tone detection? I think Neranza wants that Broadsoft should add T38 stream in the Re-INVITE, probably some server configuration?? Please correct me if my interpretation of the original query is wrong.

I am sending to a PSTN FAX so the Broadsoft server is terminating SIP point and it should send me REINVITE for T38 but it does not. It is just accepting the FAX transmission over G711. My question is there some specific advertisement(media attribute or media description) which I should add in my initial INVITE request to the Broadsoft server to make it understand that I support T38? I saw also something called "Broadsoft FAX Messaging" but did not find any description.
