Voice bearer channels and transcoders are capable of sharing the same DSP. However, the conference bridge resources cannot play nice and share." <-- This matches your Q/A example above. <br /><br />This is certainly a point that is very likely to be tested in CCIE Voice.David Holmanhttps://www.blogger.com/profile/11238191012044383600noreply@blogger.comtag:blogger.com,1999:blog-3921470344483575604.post-6540617495373497682011-08-01T22:02:10.886-04:002011-08-01T22:02:10.886-04:00@elhallak - I'm going to review this material ...@elhallak - I'm going to review this material again more closely and respond as soon as I can (heading to work now).

No. Conferencing needs a dedicated DSP resource. If a DSP is assigned for a conferencing session, then it cannot be used for transcoding or voice call initiations or terminations. Transcoding and voice calls can share the resource of a single DSP, however. Note that conferencing needs a dedicated DSP, but not a dedicated PVDM2 module. For example, PVDM2-64 contains 4 DSPs; if one of them is used for conferencing, the other three can still be used for other purposes.<br /><br />http://www.cisco.com/en/US/prod/collateral/modules/ps3115/ps6024/prod_qas0900aecd8016c6ad_ps5855_Products_Q_and_A_Item.htmlAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3921470344483575604.post-37176726854416263542011-08-01T21:26:37.402-04:002011-08-01T21:26:37.402-04:00Hummm , I'm a little bit confused
