Is there a better way to attach logs? I am not sure if attaching them with email is good enough. Also how do i prefix uuid to mod_spandsp logs? On Tue, Apr 19, 2011 at 7:15 PM, Sadhika Sharma <sadhika@gmail.com> wrote:
Thanks Steve for replying,
I will explain the problem in clearer terms. Whenever a call lands on freeswitch machine, I exceute rxfax(). I get about 5000 fax calls every month, out of which about 800 transmissions fail due to hangup cause 548 'Disconnected after permitted retries' Complete log is attached.

Sadhika,
If you post only a fragment of a log, and describe only half of what happens, people will generally ignore what you post. I guess they don't like being treated like they are mind readers.
The error seems pretty clear. You aren't getting anything from the far end. Since you give no clue as to what you are doing, beyond trying to receive FAX, that's about as detailed an analysis as you are going to get.

Hi,
I need help in debugging hangup cause 548, 'Disconnected after permitted retries' while attempting rxfax().
Logs show that T4 expires in phase T30_PHASE_B_RX. T30 PHASE B concerns exchange of DIS/DCS messages. After sending DIS, mod spandsp keeps waiting for DCS and exhausts its retries.
Please guide me how to debug the root cause of loss of DCS message. Logs are mentioned below:
