You should check with your the sip trunk provider about what they're expecting from your side of the house. This would be a good start. Are they expecting call control from a specific IP? Are they going to bounce you if your ANI isn't within the agreed upon range?

I had access to basically all the applications that were covered on the test. A lot of the stuff I had familiarity since I also work in the UC domain.

I also read the book and the SRNDs. I had a lab of routers/switches/phones that I picked up to learn about CME. I'm lucky because I'm very curious by nature and end up reading/learning about many things that just happened to be covered in the exam blueprint.

Honestly after all that, the most useful thing that helped me pass the test was failing on the first try. After the first try I knew more of what types of questions would be asked and what I needed to study. It was a humbling experience failing on the first try given that I have years of experience with Cisco UC.

Just remember that whether you pass or fail, it is not a measure of your worth. It's only a measure of whether or not you can answer enough of the 60 or so questions correctly.


How were each of the tests? Did they feel like they were meaty and "valuable"? Or did they feel like they tested you on many things superficial? Did you use the foundation learning guide, SRND white papers, and labbing it up?

For instance, I felt that the CCNA Collab materials/topics were great. But I also felt like the tests didn't validate the knowledge all that well. Many questions were superficial and simply based on rote memorization of things not built on the foundation of understanding. I don't even know if that last sentence makes any sense.

I want the CCNP to mean something to me. To feel that the CCNP adds value that just simply studying the material does not. I know that's subjective. I guess I don't want it to feel like I just had to memorize a bunch of "readily-googleable" things or menus for half the test. That I had to actually learn and grow.


I'm totally okay with picking up a UC lab. I'm just worried about having to memorize menu trees and the like. And that there only are foundation learning guides and the exam blueprint. I almost feel like I'll be thrown to the wolves.


I tried skydiving once. Threw up all over myself and the poor guy attached to me. We did these hard turns to increase the speed of our descent, once the parachute opened.

When I told the guy I was gonna throw up, he did more of the turns to keep vomit away from us. This led to more vomiting. It was a vicious cycle.

I should have taken dramamine.

I think you can apply the same logic from the other CCNA certs. Certs with no experience is not super useful. Experience without certs is good. Experience with certs is best.

Cisco just revamped the Voice/Video certification track into Collab without the dependency on CCNA R/S so I think that should indicate how the industry is evolving in a general sense.

Thanks for the info. When you say white papers, you mean the Collaboration 10/11.x SRND? Or are there more specific ones for video? Did you get a lot of model comparisons on your exam? Or "which features does the XXXX model phone have"?

the OCG actually is very helpful and I would recommend it for folks getting into the Unified Communications space. The OCG maybe accounted for 50%-70% of the test material. It's a good book, really. Just not that good if you expect it to prepare you for the exam.

[–]flying_scruntCCNA R&S, Collaboration[S]

I felt the test was difficult. I'm not sure how much I'm allowed to say from the NDA you have to sign. You definitely need to study more than just the OCG. Be resourceful in finding all the things you need to know. Practice Exams. Forum posts. There was one post on Cisco's forum in particular that was very helpful.

[–]flying_scruntCCNA R&S, Collaboration[S]

Do not rely solely on the OCG. It is not comprehensive. Use Practice Exams and Exam Topics from the Cisco website:

And as much as it sucks to admit, taking/failing the exam the first time really helped too. I got super crushed the first time. But it showed me some of the things that I needed to know and what to expect on the next try.

[–]flying_scruntCCNA R&S, Collaboration[S]

Did the OCG cover all the material you needed? Was the list of Exam Topics from Cisco comprehensive for the test? I had some topics on the CICD that weren't covered in the Cisco "Exam Topics". How crucial is it to lab up telepresence and stuff? that stuff is expensive!

I feel your disappointment. I recently did exactly the same. CiscoPress book, Boson practice exam. Failed. I'm trying to figure out exactly what I need to know, instead of "Describe CUCM components and their functions", which I feel is quite open-ended.


I've had something similar to that, after upgrading from 8.6 to 10.5. IIRC it ended up being a certificate problem between our pub and sub. I know it sounds a little weird, but I think it's worth at least some measure of investigation. If I the solution comes to me more clearly, I'll PM you.


Ok, but it's not possible on the pots dial peer. Do I need to make another dial peer with incoming called number and not point it anywhere?

You should have a voip dial peer, for the call leg between your PBX and the CUBE, which uses that sip trunk. On the voip dial peer you can add rtp-nte for your dtmf relay. I would guess that you have an outbound dial-peer for your ISDN/PSTN side.

dial-peer voice 100 voip

  • description calls routed to your PBX
  • destination pattern <insert pattern here>
  • session-target ipv4:<IP of PBX>
  • dtmf-relay rtp-nte
  • session protocol sipv2
  • yadda yadda

side note: typically you would want 2 dial peers, at least, for for a given call (an inbound and outbound). Technically in some situations a single dial peer will match for both call legs, but I would try to avoid that as it's not flexible at all.

second side note: if you don't specify any dtmf-relay methods, DTMF tones will simply be left in the audio stream. I believe a DSP would convert NTE DTMF packets into tones in the audio stream for outbound....and the inverse for inbound.....I think.
