is that the seize ack transmited from OpenR2 is not detected by the other end and it ends the call, because whenever it fails, the release comes exactly 41ms after the seize ack has been sent in all cases, but I'm not sure, i dont have traces in the other

<div>Thanks Ezequiel<a id="LPlnk865984" previewremoved="true"></a><a id="LPlnk284820" previewremoved="true"></a>.</div>
<div><font face="courier new"></font><br>
Very strange with another PBX doesn't occurs the phenomenon (could provider more details about PBX? IP or TDM<a id="LPlnk597301" previewremoved="true"></a> PBX??).<br>
By the other way could help if can provide more detail or explain how users perceive the phenomenon.<br>
According to trace log, Normal Clearing comes from origination call side and assume the call have aborted (it doesn't see a delay on line sequences on seizure Ack<a id="LPlnk660273" previewremoved="true"></a><a id="LPlnk615144" previewremoved="true"></a>),
so question is why on other PBX it doesn't happens and with your Asterisk it happens, still without understand how troubles o phenomenon are detected.<br>
Best regards.</div>

<div>The issue is that with another PBX the calls have no problem, all are handled correctly, therefore the provider argues that a problem is the new PBX.</div>

<div>Hi Ezequiel<a id="LPlnk491698" previewremoved="true"></a>.</div>
<div><br>
First of all there are no logical reason and technical way to set two channels for a same call (no sense to a configuration issues).<br>
Therefore how you can determine from a CAS line signalling is regardless to the same call? because on your trace it exactly show the same line sequences without any information about call of Inter-register Signalling (Call Setup), both calls have ended by
the same reason (the call have disconnected from the far side). <br>
Sorry based on your information it doesn't seems to identify a problem for a; one call is handler correctly and the other fail, have contacted with Telefonica<a id="LPlnk816124" previewremoved="true"></a><a id="LPlnk712811" previewremoved="true"></a><a id="LPlnk800287" previewremoved="true"></a>
to let you know about why some incoming calls are released without exchange of R2<a id="LPlnk246524" previewremoved="true"></a><a id="LPlnk264985" previewremoved="true"></a><a id="LPlnk258622" previewremoved="true"></a> signals?.
