Hi to all Sorry to bump this old thread. Well, I found a while ago finally the reason why T.38 doesn't work in conjunction with Swiss VoIP provider sipcall. Despite T.38 is stated as "supported", that provider does NOT support T.38. Their T.38 gateway has some fundamental negotiation problems, - it "exceeds the T4 timer of the T.30 protocol". Therefore, T.38 faxing does not work. http://wiki.innovaphone.com/index.php?title=Howto:Sipcall_business_-_SIP_Provider_Compatibility_Test Sipcall has confirmed me that they work now on a solution. Will see... Kind regards, Clemens -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
