 CSeq exactly the same way as TM does. This is good for reboot - than messages belonging to transaction lost due to reboot will still be forwarded with the same branch parameter and will be match-able downstream.

 If the internal resolver/cache is enabled you can add/remove records by hand (using sercmd or xmlrpc) using the DNS RPCs, e.g. dns.add_a,
-dns.add_srv, dns.delete_a a.s.o. For more info on DNS RPCs see http://sip-router.org/docbook/sip-router/branch/master/rpc_list/rpc_list.html#dns.add_a

 Note: During startup of SIP-Router, before the internal resolver is loaded, the system resolver will be used (it will be used for queries done from module register functions or modparams fixups, but not for queries done from mod_init() or normal fixups).

+===== UDP Parameters =====
+==== udp4_raw ====
+Enables raw socket support for sending UDP IPv4 datagrams (40-50% performance increase on linux multi-cpu).
+Possible values: 0 - disabled (default), 1 - enabled, -1 auto.
+In "auto" mode it will be enabled if possible (sr started as root or with CAP_NET_RAW). udp4_raw can be used on Linux and FreeBSD. For other BSDs and Darwin one must compile with -DUSE_RAW_SOCKS. On Linux one should also set udp4_raw_mtu if the MTU on any network interface that could be used for sending is smaller then 1500.
+The parameter can be set at runtime as long as sr was started with enough privileges (core.udp4_raw).
+<code>
+udp4_raw = on
+</code>
+==== udp4_raw_mtu ====
+MTU value used for UDP IPv4 packets when udp4_raw is enabled.  It should be set to the minimum MTU of all the network interfaces that could be used for sending. The default value is 1500. Note that on BSDs it does not need to be set (if set it will be ignored, the proper MTU will be used automatically by the kernel). On Linux it should be set.
+The parameter can be set at runtime (core.udp4_raw_mtu).
+==== udp4_raw_ttl ====
+TTL value used for UDP IPv4 packets when udp4_raw is enabled. By default it is set to auto mode (-1), meaning that the same TTL will be used as for normal UDP sockets.
+The parameter can be set at runtime (core.udp4_raw_ttl).
