After sending faxes (it works very well know, thanks to Anthony Minessale) , sometimes I've got errors like that:

- Disconnected after permitted retries

- No response after sending a page

- Received a DCN from remote after sending a page

- Received bad response to DCS ot TCF

- The call dropped prematurely

- Timed out waiting for initial communication

Those faxes are about 25% of all faxes that I send. I'm using the last git version.

Where this problem comes from? Is there a way to fix this?

I know that sometimes the remote end could be broken or could be an old fax machine, but it seems strange that I have so many errors like that.

Thank you for your help :-)
