[Asterisk-Users] Major issue: More incompatible frame messages

[Joseph Rothstein]

It seems that the problem only occurs when there is a redirect:
   
 -- Executing Dial("Zap/19-1", "SIP/123|40|t") in new stack
    -- Called 123
    -- Got SIP response 302 "Moved Temporarily" back from 10.139.2.5
    -- Now forwarding Zap/19-1 to 'Local/103 at sip' (thanks to SIP/123-878b)
    -- Executing Macro("Local/103 at sip-1b31,2", "stdexten") in new stack
    -- Executing Set("Local/103 at sip-1b31,2", "LANGUAGE()=en") in new stack
    -- Executing SetMusicOnHold("Local/103 at sip-1b31,2", "aviareps") in new
stack
    -- Executing Dial("Local/103 at sip-1b31,2", "SIP/103|20|t") in new stack
    -- Called 103

I really hope that someone can shed some light onthis problem.
