I hope I am in the right forum, if not, please let me know.
I' ve been researching this and cannot find a definitive answer. Currently in our lab, we have the SR140 server directly connected to Avaya SM via entity links and we are making and receiving faxes outside the enterprise using AT&T IP Flexible Reach SIP trunking.
Per all the configuration docs and tech notes, there is a Avaya CM connected as well. As I understand the documents, these are only needed for the medpro resources, which would be used for codec renegotiation or transcoding. Any other reason these are needed?
If the SR140 can determine the codec (either T.38 or G711), what would be the need of CM in the fax infrastructure? Maybe only for internal faxing between analog stations and the SR140?
I appreciate any help. Thanks, Dan
