I have been trying to solve this problem for a couple of hours, but i could'n. Could somebody help me?

I have configure a voice mail system (http://iptel.org/~faqomatic/fom-serve/cache/92.html) and I have a problem when it answer the call; it doesn't stop recording when I hang on the phone and never sends the mail. this is the sems debug:

------------------------------------------------------------------------------------------------------------------------------------------------

(815) DEBUG: write_to_fifo (AmRequest.cpp:708): Write to fifo: completed

---------------------------------------------------------------------------------------------------

it never never gets the:

DEBUG: getReturnCode (AmRequest.cpp:421): response from Ser: 200 fifo_t_reply succeeded

and sends the mail. When I call the voice mail with an ATA pointing to port 5090 (SER voice mail) it works ok and sends the mail.

The system is configured with 2 SER, one for routing and the other for voice mail.

Find attached the configuration files.

Thank you in advance
