<div dir="ltr">Dear list,<br><br>We have recently deployed an openr2 xorcom system, carrier is TELMEX with an E1. We are using 10 channels only. We have been experiencing some "protocol errors". The channels get blocked and some blue alarms are raised, but they get clear later. <br><br>Here is the configuration:<br><br>/etc/dahdy/system.conf<br><br>span=1,1,0,cas,hdb3<br>cas=1-15,17-31:1101<br>echocanceller=oslec,1-15,17-31<br>loadzone = mx<br>defaultzone = mx<br><br>/etc/asterisk/dahdi_channels.conf<br><br>signalling=mfcr2<br>mfcr2_variant=mx<br>mfcr2_get_ani_first=no<br>mfcr2_max_ani=10<br>mfcr2_max_dnis=4<br>mfcr2_category=national_subscriber<br>mfcr2_call_files=yes<br>mfcr2_logdir=span1<br>mfcr2_logging=all<br>mfcr2_mfback_timeout=-1<br>mfcr2_metering_pulse_timeout=-1<br>group=0<br>context=from-zaptel<br>language=es<br>channel => 1-10<br><br>Here is the /var/log/asterisk/full output, as I mentioned before, the E1 is working fine and it presents this kind of errors randomly.<br><br><a href="http://pastebin.com/AMbUUJvW">http://pastebin.com/AMbUUJvW</a><br><br>And from the channel trace we have this output:<br><br><a href="http://pastebin.com/bpDn7pZf">http://pastebin.com/bpDn7pZf</a><br><br>Our binary versions are:<br><br>asterisk-11.7.0-1<br>dahdi-2.10.0-1<br>libopenr2-1.3.3-0<br><br>My guess is that it is a carrier issue since we have the blue alarm. But, I would like to be sure not to be hitting a bug with our versions.<br><br><div>Thank you in advance,<br clear="all"></div><div><br></div><div><div dir="ltr"><img src="http://tiendaip.mx/img/firmas/firma_larm.png"><br></div></div>
