I'll start by assuming your config is correct. Then, the first thing I try is as follows:
no mgcp mgcp bind media source lo0 <<<< or whatever interface you are using mgcp bind control source lo0 mgcp bind media source lo0 mgcp bind control source lo0 mgcp This *usually* clears it up, assuming the configuration is correct. If that doesn't work, take it one step further to reapply the L3 bind command no mgcp int s0/0/0:23 no isdn bind-l3 ccm mgcp bind media source lo0 <<<< or whatever interface you are using mgcp bind control source lo0 mgcp bind media source lo0 mgcp bind control source lo0 int s0/0/0:23 isdn bind-l3 ccm mgcp This should take care of it. (Note, I haven't had to use this more elaborate method in a while - if there's an error when trying to remove L3 bind from serial interface, you will need to shut the voice-port then the serial interface, run the commands above, then no shut the serial and then finally voice-port, lastly turning on mgcp). A few other notes - I typically use the ccm config method to build mgcp, then issue "no ccm config" after it is built from the CUCM download. I noticed recently in my home lab is that I was applying the command "ccm-manager switchback immediate" BEFORE letting CUCM build the full mgcp config - the issue here is that CUCM does not properly set the switchback method to immediate (even when set in the GUI, on these versions of sw/ios) and it reverts back to graceful switchback (as indicated using "show ccm"). To correct this I now apply this command (and all others extra ccm/mgcp command, such as "ccm music") AFTER config download and "no ccm config." For giggles I reapply the bind commands as well using the first set of commands at the top of this email. The last couple times I did this in practice I have not had any TEI_Assigned and now that this is my routine it takes very little extra time versus doing a minimal config and then troubleshooting mgcp later if needed. When in doubt, reset MGCP from the gui and from cli using no mgcp, mgcp. (The latter is required if you are NOT using ccm config or have removed it. Even when ccm config is left in for a full 23 channel PRI its a good idea to reset mgcp from cli.) Hope this helps... -Justin On Tue, Oct 1, 2013 at 11:04 AM, Anthony Nwachukwu <anwachu...@apafrica.com>wrote: > > Hi, > > I need help I am setting up MGCP on a 2811 router I am getting > TE1-ASSIGNED. > > CorpHQ#debug isdn q921 > debug isdn q921 is ON. > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > ISDN Se0/0/0:23 Q921: User RX <- SABMEp sapi=0 tei=0 > ISDN Se0/0/0:23 **ERROR**: L2IF_SendPkt: idb is NULL > ISDN Se0/0/0:23 **ERROR**: process_rxdata:L2IF_SendPkt Failed > CorpHQ# > > All possible debugging has been turned off > CorpHQ#show isdn sta > Global ISDN Switchtype = primary-ni > ISDN Serial0/0/0:23 interface > dsl 0, interface ISDN Switchtype = primary-ni > Layer 1 Status: > ACTIVE > Layer 2 Status: > TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED > Layer 3 Status: > 0 Active Layer 3 Call(s) > Active dsl 0 CCBs = 0 > The Free Channel Mask: 0x80000007 > Number of L2 Discards = 0, L2 Session ID = 6 > --More-- > > > _______________________________________________ > For more information regarding industry leading CCIE Lab training, please > visit www.ipexpert.com > > Are you a CCNP or CCIE and looking for a job?
