You basically allow calls to connect between two protocols - example:<br /><br />voice service voip<br />allow-connections h323 to h323<br /><br />The above will enable a call from h323 (CM to gateway) to the next leg of the call (h323 - gateway to PSTN).

Unity Connection especially needs a lot of memory, I believe 2GB is the absolute minimum.

I don't think you need to have a full fledged lab for the CCVP exam though. CCVP is mostly focused on the theory behind VoIP, focusing on QoS, Gateways and Gatekeepers and CCM in general. If you have a good working knowledge of the above, CCVP should be fairly easy. I'd rather spend more on good books for CCVP than lab equipment. jayanmhttps://www.blogger.com/profile/06889208413106220487noreply@blogger.comtag:blogger.com,1999:blog-6736157538468755221.post-12508700630576197132010-07-07T07:30:58.049-05:002010-07-07T07:30:58.049-05:00Trying to understand this topology.
