      intermittent and unreproducible in my case. The sad truth (for a

thank you very much for your answer and the Dahdi patch (<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://jira.freeswitch.org/browse/FS-5898">http://jira.freeswitch.org/browse/FS-5898</a>).
However we are using Sangoma and don't know yet how to adapt this patch for our cards.
Does anyone know how to do this?
