Does cisco have any Doc. that list all the ports number that Voice over IP use all Kind of protocls for all product or the major products
Aprreciate if any one have any information to this kind of documents.
Please take a look at the following link which lists all ports used by Communication manager and VOIP end points to communciate with it.
Most of the products have this either as separate doc as CUCM or within the RNs from some other products like CUPC.
We don have a master doc for all products, you need to search for this per product.
ie For CUCP just look the RNs for the version you need and there is a section which covers which ports are necessary for it to work.
If this helps, please rate
