That sounds possible! Thanks.
That does this description mean: “Execution time of load_gws() function is O(N) * O(M), where
N is number of different prefix lengths and M is number of collisions for matching prefix(es) in lcr rules hash table of the LCR instance.”?
Does this mean it loads the data from its internal memory or does it load the data from the database again?
How fast does it select a gateway after load_gws using next_gw()? Is it O(N) again?
What about multiple combinations of capabilities? For example caller id spoofing and g729 codec, or caller id spoofing and g711ulaw codec? Etc.
Wouldn’t this cause the data to grow exponentially?

Subject: Re: [SR-Users] LCR with gateway capabilities
What about configuring two LCR instances with different "lcr_id".
The first one can use only gateways with requested capabilities and the second one all gateways.
Then you can make a decision about which instance to use during call routing process providing this lcr_id to load_gws() function.
Hello,
From what I understand about the LCR module is that the rules have to be prioritized by the admin, be it manually or automatically by an application.
Let’s say the LCR database has 10 gateways, each with their own rules etc.
4 of these gateways support caller id spoofing and the others don’t.
But the other 6 are cheaper and Kamailio has to route a call using a gateway which support caller id spoofing and is the cheapest of the 4.
Would it be possible to tell the LCR module to select a gateway based on certain capabilities and is the cheapest of the ones which support a certain capability?
