[Asterisk-Users] no sound. "Failed to write frame"

[Julio Cesar Ody]

Hi all,

Couldn't find a place to search the list archives...

I'm having issues in getting any sound using a fresh asterisk install
and a SJPhone to connect to it. I went by the instructions pointed at
the "10 minute guide", located here:
http://www.voip-info.org/tiki-index.php?page=Asterisk+quickstart.

I installed it on a Slackware 10.1, by using no more than "make &&
make install && make samples". Then I proceeded with installing
asterisk-addons and asterisk-sounds as suggested. Oh, and I used a
different install prefix for *all* forementioned packages. (all the
same, of course)

The thing is, soon as I get SJPhone to connect to asterisk (which
happens fine), I tried the echo service by dialing 600. Then I get:

    -- Executing Playback("SIP/julio-5ae7", "demo-echotest") in new stack
    -- Playing 'demo-echotest' (language 'en')
Jul  4 14:35:42 WARNING[13521]: file.c:550 ast_readaudio_callback:
Failed to write frame
  == Spawn extension (default, 600, 1) exited non-zero on 'SIP/julio-5ae7'

Then I dialed 1000, for the "congrats" message: That's what I get:

    -- Executing Goto("SIP/julio-f0ed", "default|s|1") in new stack
    -- Goto (default,s,1)
    -- Executing Wait("SIP/julio-f0ed", "1") in new stack

    -- Executing DigitTimeout("SIP/julio-f0ed", "5") in new stack
    -- Set Digit Timeout to 5

    -- Set Response Timeout to 10
    -- Executing BackGround("SIP/julio-f0ed", "demo-congrats") in new stack
    -- Playing 'demo-congrats' (language 'en')
Jul  4 14:37:05 WARNING[13523]: file.c:550 ast_readaudio_callback:
Failed to write frame
  == Spawn extension (default, s, 5) exited non-zero on 'SIP/julio-f0ed'

Again, asterisk seems to be unable to write any sound to the frame.
Any ideas on why that could happen? Thanks for any advice.
