[SR-Users] Changing Domain in To URI
Hello, As it happens we run Kamailio 3.2.0 on Debian Lenny which for some reason does not support uac_replace_to()! Anyhoo, we are trying to change the domain part in the To URI. What is the best way to do it ?

However, There is not an easy way to find the Registration with TCP socket info (IP and Port of the Client). Could anyone suggest a solution? you can use set_forward_no_connect http://www.kamailio.org/wiki/cookbooks/4.0.x/core#set_forward_no_connect Local branches will be created, but not forwarded if no connection matches the destination. If you follow the code for this functionality, then you should see how the connection is associated with a destination.

Is there any plan in supporting more one mode (or dropping the other) in the future? Not per se, kernel mode forwarding (at least for the primitive case with no modifications to the packets) will always be the primary means of forwarding packets. At the same time, user-space forwarding will also always be available, since at least the first few packets must always be processed by the daemon. As such, it doesn't really have two modes of operation, it will simply fall back to user-space processing if the kernel modules fails to do its job for whatever reason. It's designed to use the functionality of the kernel module if possible, but also not to rely on it. She fallback to user space can happen even during a call? Or is just about when the call is initialized, the application detects is some problem when setting up forwarding rules in the kernel and goes for user space. Have you done some measurements to see the benefits of kernel forwarding vs user space? I can't quote any specific numbers, but we've seen several times in the past that the overhead of pushing packets back and forth between kernel and user space is quite significant. I suppose I could try to set up some simple tests to get some unscientific ballpark numbers if people are interested. Indeed, this is kind of general feeling, at least based on theoretical aspects, but I haven't seen any kind of numbers just to compare and see how much is worth to go for kernel forwarding.

The socket remains open and the daemon continues to listen for packets on it. If the daemon receives a packet, it will process it, which in the normal case will result in it being forwarded. With the kernel module active and working, the daemon will simply not see the packets coming in on the socket. > Indeed, this is kind of general feeling, at least based on theoretical > aspects, but I haven't seen any kind of numbers just to compare and see > how much is worth to go for kernel forwarding. I did a very simple test, one pseudo-call (one port in, one port out) with about 35,000 UDP packets per second going each way. Each packet had 150 bytes payload and the test was done on an 8-core Xeon 2.53 GHz machine running kernel 2.6.32. Under this workload, the daemon registers with about 90% single-CPU load without kernel forwarding. The daemon is multi-threaded and so can use multiple cores, but if it weren't, then it would be about maxed out at this point. Averaged over the 8 cores this leaves the system around 88% idle.

Re: [SR-Users] Changing Domain in To URI
Let me also explain a bit what I'm trying to fix through this method. We have an Asterisk box that forwards call through kamailio to one of our carriers. That works great. The calls are being forwarded with a To of: 5551112...@kamail1.domain.com towards our carrier We also added another kamailio 'load-balancer' (using dispatch module ) box in the middle of all this to try and eventually load balance the calls. So the setup looks like this: Asterisk -> Kamailio Load Balancer -> Kamailio gateway -> Carrier. The problem with this setup is that now our carrier doesn't accept the calls and returns a 500 - Internal error message. The only difference I saw is that the To in the packets now look like this: 5551112...@kamail-load-balance.domain.com I'm thinking the carrier is blocking us based on not recognizing the domain part in the URI and that's why I'm trying to change it. Does it make sense ?

Re: [SR-Users] Changing Domain in To URI
Mersi mult Daniel! It worked but unfortunately it didn't fix the issue.
As I mentioned previously the original setup is like this:
Asterisk -> Kamailio gateway -> carrier. All calls go through just fine
The new setup we are trying is:
Asterisk -> Kamailio load balancer ( dispatch module ) -> Kamailio
gateway -> carrier
With this setup the calls come back from the carrier with 500 - Internal error
I've looked at the SIP packets in both cases and they look similar.
The only difference is that when going through the load balancer the
To is different ( fixed now ) and it has 3 more VIA lines in the
header. Where can I start looking at what's causing this ?
Thank you!
