[OSL | CCIE_Voice] Voice class codec and gatekeeper
Hi, I have 2 distinct questions: 1. In the case of gatekeeper, what is the difference between hopoff and outvia? 2. Is it a good approach to use the voice class codec below for all dial-peers in the exam (with small exceptions like dial-peer to cue or bacd where you only need g711u)? voice class codec 1 codec preference 1 g711u codec preference 2 g729r8 Thank you ___ 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?

Re: [OSL | CCIE_Voice] Voice Class Codec Question
, this is a call between sites and once again, we needn't worry about the preference of codecs in the voice class command since: Site A IP Phone (Reg-SiteA) will be calling the egress GW at Site B (Reg-SiteB). If the incoming dial peer at Site B has both codecs defined, the GW will send an H.245 TCS to CUCM advertising both codecs. However, CUCM will enforce the region relationship(s) mentioned previously and will thus negotiate only G.729. Note that the preference of the codecs in the voice class codec becomes a matter of concern only when something like this happens: 1. An H.323 endpoint advertises G.711 as first preference and then G.729 2. GW advertises G729 as first preference and then G.711. In this scenario, the MSD will be the tie breaker. In most cases, for a CUCM scenario, CUCM becomes the master and wins, so to speak although I don't know of any way to define a codec preference on CUCM as such.

[OSL | CCIE_Voice] Voice class codec and default VOIP dialpeer
Hi all, I was just wondering what is the importance of creating Voice class codec on a H323 gateway? I use to create this class like: voice class codec codec preference 1 g711ulaw codec preference 2 g711alaw codec preference 3 g729r8 and then I would add it under default incoming voip dialpeer like: dial-peer voice 1 voip voice-class codec 1 incoming called-number . dtmf-relay h245-alphanumeric no vad But I noticed that this dialpeer mess up with CUE and MWI etc like different sites not reaching to Voicemail or even if they reach voicemail the MWI won't lit up. Removing this incoming voip dialpeer resolved all issues. In my lab exam, I did not use this dialpeer at all i.e. default voip dialpeer. Everything worked finebut I did not get marks as I was expecting. I am not saying that this would be the only thing where I would have lost points but could it be one of the reason? So questionis a default voip dialpeer necessary? If we create one then what codec should we use as voice class codec mess things up. Thanks.

Re: [OSL | CCIE_Voice] Voice class codec and default VOIP dialpeer
I don't think a class codec is required as long as you have the codec g711 configured on the voip dial-peer by default a voip dial-peer supports g.729 by default and CUE only supports g.711 so we either need to force that call to be g711 somehow either using a class codec command or just the codec command under the dial-peer that's just my opinion 2010/4/30 Ashar Siddiqui siddas...@gmail.com Hi all, I was just wondering what is the importance of creating Voice class codec on a H323 gateway?

Re: [OSL | CCIE_Voice] voice class codec
As has already been stated G711 should have preference over G729. This is because all of the ingress calls (PSTN to VoIP) on the BR1 GW will be going to phones at the BR1 site. So you want it to be G711. The only time an inbound call would switch down to 729 is when a call rolls over to VM (Assuming Unity is in the same region as HQ). You may also need to consider egress calls from HQ via the BR1 GW. TEHO and GW failover come to mind. You might want to use the same (711 over 729) voice class on the matching inbound dial peer for those calls as well.

Re: [OSL | CCIE_Voice] Voice-class codec and H.245 capability exchange
Found the answer myself: when voice-class codec is configured on INBOUND dialpeer, then in H.245 capabilities exchange the router advertises/accepts only the codec which is configured on OUTBOUND dialpeer. Example 1: CCMGKTBR2 (inbound DP 1003)-(outbound DP 3600)CUE H.245 shows only G.711 is accepted by BR2 from CCM, because DP 3600 has codec g711u configured Example 2: CCM-GKTBR2(inbound DP 1103)---(outbound DP 1104)---BR2 loopback---(inbound DP 1104)-(outbound DP 3600)CUE H.245 shows only G.729 ( G.729a too) is advertised and accepted by BR2 from CCM because DP 1103 has default codec (G.729).
