I have cut over an 800 # to my As5400's and a some users with USR 56k Fax modems can not negotiate a connect. Does anyone know of any possible fixes either to USR modem or As5400.
I have set modemcap on AS5400 to S29=6 to skip V.92. It appears I have the same problem if these USR modems dial an As5300 with Mica modems also.
Need some recommendations to try
