According the docs, the hash table is restricted to a maximum size of 2^16 (65536) buckets.it was restricted to 2^14, I just lifted it to positive integer range 2^31 because it is easier to get now systems with plenty of memory -- it will be in next major release.
This doesn't mean that the htable can only hold 65k entries, just that it's the maximum number of unique buckets. Assuming a theoretically ideal distribution where every value has a unique bucket, after 65k values, you will get collisions. Collision chains attached to buckets are linear lists. After collision chains get deep, performance becomes more and more linear.
So, you can put 2m values into the htable. I am not sure that it is the optimal use of an htable, however.

Asunto: Hash Table capacity
Hello list.
I have a question about the HTABLE module. Suppose that I have a mysql database with 2 million of records. Is possible to load this table as a hash table compatible with Kamailio!?
Hope someone can help me.
Thanks,
Ricardo Martinez.-
