[OSL | CCIE_Voice] UCM LOCATION QUESTION
Experts, I have a somewhat basic question just clear up something that is lingering in my mind. The example is this: In a multiple remote location site company, with a Centralized UCM architecture, each site has it's own device pool, region, and location settings. All the DN's on the phones for all sites are in the same PT, meaning calls between sites are on net via their existing WAN infrastructure and not the SIP Trunk/PSTN. Remote site A is rather large 50-60 phones. Remote site B is rather small 10-15 phones. Calls between regions use g729 Calls to the PSTN using a SIP Trunk use g711 The location setting for site A is unlimited. The location setting for site B is 256 What I am wondering is this, Site B has 3 calls to the PSTN using the SIP Trunk using g711 @ 80k per call which equals 240k. The SIP trunk is also in it's own Device Pool, region, etc. Now someone from Site A calls site B, the bandwidth at Site A is unlimited so no issue there. According to the Cisco Research I've done, a call requires 2 streams. Since Site B is using 240 of 256k of bandwidth on the 3 PSTN/SIP Trunk calls, when a g729 calls comes inbound which requires 24k which causes Site B location setting to be exceeded, will the call fail or succeed ?? IMO, the call will fail. Thanks, Stephen Manuel ___ 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?

Stephen, the call will fail you're going to get a message on the phone saying not enough bandwidth and the call will drop 2011/6/22 Stephen Manuel srman...@bellsouth.net Experts, ** ** I have a somewhat basic question just clear up something that is lingering in my mind. ** ** The example is this: ** ** In a multiple remote location site company, with a Centralized UCM architecture, each site has it’s own device pool, region, and location settings. ** ** All the DN’s on the phones for all sites are in the same PT, meaning calls between sites are on net via their existing WAN infrastructure and not the SIP Trunk/PSTN. ** ** Remote site A is rather large 50-60 phones. ** ** Remote site B is rather small 10-15 phones. ** ** Calls between regions use g729 Calls to the PSTN using a SIP Trunk use g711 ** ** The location setting for site A is unlimited.

Re: [OSL | CCIE_Voice] UCM LOCATION QUESTION
That's what I thought, but have not tested it to know for sure. As a follow up, as a general design what would be better. Using the Location setting as a form of Call-Admission-Control, or use various QOS and IOS mechanisms to implement CAC on the Gateway Routers. IMO, I would rather have CAC implemented on the Routers, leaving UCM to process calls, which is why I have usually set the Audio Bandwidth setting under Locations to Unlimited.

Re: [OSL | CCIE_Voice] UCM LOCATION QUESTION
my thoughts are if you want to use QoS you actually can't do a lot ob CAC with QoS you will degrade the quality of the call, but i don't think you can fully implement CAC with QoS. this is just my thought though. i've used only 2 types of CAC mechanisim. locations CAC or GK CAC my 2 cents hth 2011/6/22 Stephen Manuel srman...@bellsouth.net That’s what I thought, but have not tested it to know for sure. ** ** As a follow up, as a general design what would be better. ** ** Using the Location setting as a form of Call-Admission-Control, or use various QOS and IOS mechanisms to implement CAC on the Gateway Routers. ** ** ** ** IMO, I would rather have CAC implemented on the Routers, leaving UCM to process calls, which is why I have usually set the Audio Bandwidth setting under Locations to Unlimited. ** ** Thanks, ** ** Stephen Manuel ** ** *From:* Cristobal Priego [mailto:cristobalpri...@gmail.com] *Sent:* Wednesday, June 22, 2011 2:37 PM *To:* Stephen Manuel *Cc:* ccie_voice@onlinestudylist.com *Subject:* Re: [OSL | CCIE_Voice] UCM LOCATION QUESTION ** ** Stephen, the call will fail you're going to get a message on the phone saying not enough bandwidth and the call will drop 2011/6/22 Stephen Manuel srman...@bellsouth.net Experts, I have a somewhat basic question just clear up something that is lingering in my mind.

Re: [OSL | CCIE_Voice] UCM LOCATION QUESTION
If you want to be serious about doing an implementation, then you should get your answers from reading the SRND. are you familiar with that document? If you read the proper chapter, you would know the answer already and would not need to read guess recommendations where we just don't know everything about your deployment.
