#   domain- and user-preferences with AVPs
# Several of these features are only here for demonstration purpose
# what can be achieved with the SER config script language.

SER Performance

Sun, 10 Dec 2006 09:20:32 +0100

There are many ways to good performance for networking-based software. SERi performs with a large number of subscribers on a single server, sufficient for most installations. And using various techniques building a SIP network architecture, you can make SER scale to an unlimited number of subscribers. However, we want SER's core and core modules to be based on sound design principles and architected with performance in mind. These components are used by everybody, from the simplest seri.cfg for proxying large number of call per second to the small "home-grown" setup with a huge ser.cfg executing all kinds of logic for every single message.

NAThelper SIP message/OPTIONS ping functionality

Sun, 13 Aug 2006 10:02:13 +0200

Applies to version:
0.9.7-pre4 (probably all 0.9.x)

Description:

NAThelper patch from Portaone that enables the ping functionality in nathelper to send SIP message (i.e. OPTIONS) instead of 4-byte UDP packets. This is useful for NATs that ignore ping keepalives from the outside as the user agent will answer the OPTIONS packet with OK (or 404 Not found etc dependent on support for OPTIONS).

Instructions for use:

Save the patchfile to modules/nathelper directory, then (having that directory as current) use the command 'patch -p1 < nathelper_ping.patch'

OBS! You also need to edit the parser/parse_hostport.c file and remove the #ifdef _OBSOLETED and #endif around the parse_hostport() function.

Add this to your seri.cfg to enable OPTIONS messages to the UAs as keepalives:
modparam("nathelper", "natping_method", "OPTIONS")

You will see a lot 'No UACi support' warning messages in your log. These are harmless and are caused by replies to the OPTIONS message and SERi detects (correctly) these messages as originated from SER (as UAC). You can remove the warnings by commenting out in modules/tm/t_reply.c in run_failure_handler():

        /* failure_route for a local UAC? */

        if (!shmem_msg) {

          /* GVT: Commented out as nathelper sends UAC messages to UAs for keepalives. The replies

             should just be ignored... */

          /*              LOG(L_WARN,"Warning: run_failure_handlers: no UAC support (%d, %d) \n",

                                        t->on_negative, t->tmcb_hl.reg_types); */

          return 0;
