// The following are used for the call hub implementation.
//
// One call hub hash table is used for each service provider.
// When a outgoing call or is successfully made or an incoming
// call shows up, TAPI will retrieve the call ID for that
// call and stick it in the hash table using the algorithim :
//
// hashEntryIndex = callID % numHashTableEntries
//
// In the case of collision (hashEntry already in use by a
// different callID) then the DoCallHubHashing() function will
// try to create a dynamic entry to hang off the "static" entry.
//
// We will allow a total number (per table) of dynamic entries
// specified by the GetMaxDynamicHashTableEntries() macro below.
//
// We will allow a total number (per table entry) of dynamic
// entries specified by the symbolic MAX_DYNAMIC_HASH_ENTRIES_PER_SLOT
// constant below.
//
// TapiPrimes is an array of increasing prime numbers used
// for hash table sizes. We will not grow a hash table to more
// the 261983 (static) entries, this being a seemingly
// reasonable limitation at this point. If we try to hash
// a call and are unable to (out of memory, max table size, etc)
// then we will reset our internal copy of the call ID for
// the call to 0, meaning it's not hashed at all.
