From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of Alex Pishko Sent: Saturday, July 27, 2013 11:39 PM To: ccie_voice@onlinestudylist.com Subject: [OSL | CCIE_Voice] Lab 4A BR1 MGCP Issue All, Struggling with the MGCG PRI circuit in this lab. I've been through it a few times and never had issues, however for this go around I cannot seem to get L2 up when I issue the show isdn status command. Also, when I look at the serial inteface is shows up/up, however it's up/up (spoofing). The MGCP portion appears to be workign correctly as when I issue a show ccm-manager command I see it registered to the primary and within CUCM I see the PRI as registered. Below is my relevant configuration from the BR1 Router as well as the PSTN router. Also, on the PSTN I've tried to change the pri-group to just 1-3,24 both had the same result. Also, when I issue debug isdn q921 command I do not see any response for the SAMBE packet. Any help on this would be much appreciated. I'm starting to think I may have a hardware problem, but need a second or multiple sets of eyes on this before I head down that router. Thank you all.
