<div><br></div><div><br></div><div>What i have done - i have ported the bristuff datetime handling to the current libpri svn</div><div><br></div><div>On the receive side - the IE does get ignored.</div><div><br></div><div>
On CONNECT messages - when pri localtype == NETWORK it will include the DATETIME IE in the CONNECT message with the current time.</div><div><br></div><div>I think it should work as i expect it to work.</div><div><br></div>
<div>Can anyone see a possible problem within the code ?</div><div><br></div><div>I will open a bug report for it</div><div><br></div><div>best regards,</div><div>Wolfgang</div><div><br></div><br><div class="gmail_quote">

<br></div><div>i have a box in the middle setup - where asterisk is accting as a gateway. Box is using asterisk 1.8 - and latest libpri. Protocol is q.931</div><div><br></div><div>I now got a complaint that the time on the isdn phones is going to be wrong - so i have taken a look into the q.931 protocol - and found out that there is the Q931_IE_TIME_DATE element which does carry out the current time from the network to the user.</div>
<div><br></div><div>I have taken a look into q931.c - and as far as i can see - it does only dump the received IE.</div><div><br></div><div>I have searched <a href="http://bugs.digium.com" target="_blank">bugs.digium.com</a> - but can't find anything related to this.</div>
<div><br></div><div>I have seen that the bristuff patches have implemented something related to this.</div><div><br></div><div>Does anyone know if there are current patches out there for the current libpri to be able to forward such IE's when received - or to instruct asterisk to generate such an IE for a call ?</div>
<div><br></div><div>I will look at the bristuff code - maybe this functions can get ported to the current libpri...</div><div><br></div><div>best regards,</div><div>Wolfgang</div><font color="#888888"><div><br></div>
