Hi every one. I have a particular scenario. <br><br>Nortel BCM 400 -------- E1 (mfc/r2) ----------- Asterisk ------- Telco<br><br><br>When I press 9 from any nortel extension, the BCM receive a dialtone and I received the next message in the full log. <br>

[Mar 4 19:39:30] VERBOSE[3820] chan_dahdi.c: New MFC/R2 call detected on chan 38.<br><br>after this log, the call continues correctly . The problem is when the BCM want's to take a seize and the next channel in the hunt group is busy. When this happens I just receive something like this:<br>
<br>VERBOSE[3921] chan_dahdi.c: New MFC/R2 call detected on chan 40.<br><br>and there is not dial tone. I just listen a silence. And I can't process the call. I have to hung up and try again.<br><br>I think that chan_dahdi doesn't inform to the BCM the channel status. Any Ideas?<br>
<br>My config is the next:<br><br># Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER) TELMEX<br>span=1,1,0,cas,hdb3<br># termtype: te<br>cas=1-15:1101<br>cas=17-31:1101<br>echocanceller=oslec,1-15,17-31<br><br>
