Re: [OSL | CCIE_Voice] 7960 CUCM SIP Registration
Sip phones require an extension to register. Also make sure your replication is working... maybe your phone is programmed in the pub, but the sub doesn't have it in its database. Good luck.

This means that neither ephone nor ephone-dn configuration that has been built by the IOS using SNAP will show up in the running-configuration. However it is possible to create manual ephone-dn’s that are used by features such as ad-hoc and meet-me conferencing. This is the advantage of this mechanism versus call-manager-fallback. You may probably try with "srst mode auto-provision all” command to see all the ephone related information in the running config and delete ephone DNs. Regards.. Ashok.

Re: [OSL | CCIE_Voice] MGCP TroubleShooting
Every (normal) teardown in MGCP begins with MDCX (and "M: recvonly") and then teardown is complete with DLCX. There is a slight difference in debug order if you are debugging both Q931 and MGCP packets but in normal cases you should see MDCX then DLCX in all teardowns (except temp failure or other anomalies). IF PSTN side ends call (from GW perspective): 1. *trigger* PSTN side ends call 2. *Q931 RX disconnect *(PSTN to CUCM via GW) 3. *MGCP MDCX* (CUCM to GW) 4. MGCP 200 OK (GW to CUCM) 5. *MGCP DLCX *(CUCM to GW) 6. MGCP 250 OK (GW to CUCM) 7. *Q931 TX release* (CUCM via GW to PSTN) 8. *Q931 RX release complete* (PSTN to CUCM via GW) IF CUCM side ends call (from GW perspective): 1. *trigger* IP phone ends call (SCCP or SIP to CUCM) 2. *MGCP MDCX* (CUCM to GW) 3. MGCP 200 OK (GW to CUCM) 4. *Q931 TX disconnect*(CUCM via GW to PSTN) 5. *Q931 RX release *(PSTN to CUCM via GW) 6. *MGCP DLCX* (CUCM to GW) 7. MGCP 250 OK (GW to CUCM) 8. *Q931 TX release complete* (CUCM via GW to PSTN) To replicate these logs above you need to turn on only two debugs: debug mgcp packets debug isdn q931 In other words, in MGCP you always have MDCX/200 OK then DLCX/250 OK. For ISDN you always have DISCONNECT (side that hung up), RELEASE (side that didn't hang up), and RELEASE_COMPLETE (side that hung up. The side that hangs up dictates how the MGCP and Q931 messages are interleaved. Does this help? I know the real question you're asking is which answer is the lab looking for - I cannot answer that but it depends on the question's wording. I haven't passed yet but I believe I got an MGCP debug question correct based on my score report. If the question states "show the MGCP/Q931 debug where the call *begins to teardown*" I would personally use MDCX/DISCONNECT. If the question states "...where call *teardown is complete*" then I would use the DLCX/RELEASE COMPLETE. If the question is not worded clearly then talk to the proctor - if you explain that you understand the FULL teardown process (similar to above) but you are not sure which to use, they will understand that you know what you are doing and not just fishing for an answer. Still, you may get the common "use your best judgement" response...because they cannot answer confirming questions. Worst case, if after all this you still weren't sure, you could include BOTH debugs in the notepad file and put comments in there explaining the start/end of the teardown. -Justin On Wed, Jul 17, 2013 at 2:22 PM, IE Target wrote: > The message which indicates that an MGCP call is tearing down is > > MDCX or DLCX.?? > > Some guys say that it is DLCX no MDCX > > May be some one who got marks in this section can clarify > > > Thanks > > ___ > 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?
