Spandsp FAX Driver Q?

[izrodix]

Hello Guys,
Can you please explain me what does this error mean?

"Selected FAX technology module (Spandsp FAX Driver) does not support reserving sessions."

Running software versions:
- FreeBSD OS
- asterisk18-1.8.32.2
- spandsp-0.0.6

Comment from the source code:

Code: Select all

/*! \brief Reserve a fax session.
* \param details the fax session details
* \param token a pointer to a place to store a token to be passed to fax_session_new() later
*
* This function reserves a fax session for use later. If the selected fax
* technology does not support reserving sessions a session will still be
* returned but token will not be set.
*
* \note The reference returned by this function does not get consumed by
* fax_session_new() and must always be dereferenced separately.
*
* \return NULL or an uninitialized and possibly reserved session

I presume you have tried to use a feature only supported by Fax for Asterisk., However, this forum does not support anything but Fax for Asterisk!
