[OSL | CCIE_Voice] TEHO - RTP packets seen when call haven't been answered yet?
Hi folks, When testing Vol. 1 Lab 10 question 10.3 (IOS QoS), I noticed that when a TEHO call is made (either from HQ or BR1), I see packet-count in the LLQ increment. When I say call is made, I mean the numbers are dialed, the destination phone is ringing but not picked up/answered yet. The LLQ is only configured to match "rtp audio" packets; it does not match on rtcp. Where do these RTP audio packets coming from (when the call is not even answered yet)?

[OSL | CCIE_Voice] sending CUCM traces to syslog
Hello, Is there a way to send traces directly from CUCM to syslog? Looking at traces via the CLI is really cumbersome. The syslog agent in enterprise parameters is not it. -- Thanks. tnn314.wordpress.com ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
Re: [OSL | CCIE_Voice] CCIE Voice Vol 1 Lab 5c - Transcoder
Hi, I don't think the AIM-VOICE-30 supports transcoding or conferencing but voice termination services only, so in this case you may need to install a NM in your 3725 to move on, Thanks, On Sun, Feb 14, 2010 at 12:07 PM, CCIETalk.com wrote: > I was working through lab 5c and came across the task where I had to > configure a transcoder.

Re: [OSL | CCIE_Voice] Vol 1 - Lab 5 - Task 5.5 / Setting up TEHO for 212 calls from BR1 through HQ H.323 GW
Hey Matthew, That's the expected behavior since h.323 gateways don't support the + character sending, so if you still want to send that character out to the pstn you should handle it from the router itself (for example voice translation rules), You will find more information in: http://www.cisco.com/en/US/partner/docs/voice_ip_comm/cucm/admin/7_0_1/ccmsys/a03rp.html#wp1166491 Thanks, On Sun, Feb 14, 2010 at 2:38 PM, Berry, Matthew J. wrote: > Vol 1 - Lab 5 - Task 5.5 / Setting up TEHO for 212 calls from BR1 through > HQ H.323 GW > > I can get TEHO to work when dialing a 617 area code number from HQ Phone 2, > routing the call over the WAN, out the BR1 MGCP gateway.

[OSL | CCIE_Voice] Vol 1 - Lab 5 - Task 5.5 / Setting up TEHO for 212 calls from BR1 through HQ H.323 GW
Vol 1 - Lab 5 - Task 5.5 / Setting up TEHO for 212 calls from BR1 through HQ H.323 GW I can get TEHO to work when dialing a 617 area code number from HQ Phone 2, routing the call over the WAN, out the BR1 MGCP gateway. It works like a charm. It appends the + which seems to come from the 9.1617XXX translation pattern in PT-HQ-PSTN. Problem: I cannot get the + to be sent out when setting up TEHO for 212 area code calls from BR1 through HQ's H.323 GW. All of my settings for the BR1 site are identical to the HQ site. My only guess is that TEHO over WAN and out the BR1 MGCP gateway is using MGCP and not H.323. I can append a + using a dial-peer on the H.323 gateway, but I'm not sure if that is the best way to do it. It seems like Ben was saying that however you produce the end results in the lab is all that matters. What do you guys think? Am I missing something?

[OSL | CCIE_Voice] Adjust 3750 Egress Priority Queue Bandwidth
I wanted some thoughts on how others would handle a request to tweak the amount of bandwidth availble to an egress priority queue on a 3750. So for example a request to allocate 25% of available bandwidth for switchports connected to IP phones on the 3750. I have heard suggestions to handle this in the following manner - this is assuming auto qos voip trust cisco-phone has been run on the port already: interface fa 1/0/2 no priority-queue out srr-queue bandwidth shape 4 0 0 0 srr-queue bandwidth share 0 33 33 33 But I'm struggling to see that this meets the requirement. In this configuration we would be enabling shaping of queue 1 and assigning it 25% of available bandwidth. Then assigning remaining bandwidth equally to the remaining three queues. But this does not appear to be meeting the requirement of assigning the priority queue 25% of the bandwidth. We would be assigning the queue that RTP traffic is placed in by default 25% of total bandwidth but the initial no priority queue out command technically disables a strict priority queue and thus it does not seem to fit the requirement. Thoughts? While I struggle to see the disablement of the priority queue as strictly meeting the requirement - I also find no explicit means to allocate the priority queue a strict amount of bandwidth (I.e. the equal if the ingress queue command - mls qos srr-queue input bandwidth 75 25 that could be used to meet this requirement for default priority ingress queue 1. How about skipping the initial no priority queue-out command but only issuing the shape and share commands as specified above? Wouldn't leaving the priority queue enabled and assigning it a shape value of 25% (1/4) satsify the requirement better?
