More about locally generated 408

by Iñaki Baz Castillo

Hi, I would like to insist in the 408 problem when it's locally generated due to fr_timer timeout in SIP UDP. Let's suppose this very simple example: - Call from UAC to proxy. - Proxy routes it to a gateway (no failover to other gateways). 3 cases: a) Gateway replies 408, so TM selects 408 (OK). b) Provisional responses are received but fr_inv_timer expires, so TM generates a local 408. The client receives 408 (OK). c) No reponse at all from gateway so fr_timer expires and TM generates a local 408. The client receives 408 (WRONG). Obviously in case "c" it doesn't make sense to send a 408 to the client as the fact is that the gateway is unreachable, so a 500 should be replied to the client. So what is the problem? In case "c" there should be a "transport error". According to RFC 3261 if an UDP transaction gets a ICMP "port unreachable" it should generate a local 503. And if it receives no UDP reply at all (neither an ICMP notification) then it should generate a local 408. Problems with this: - SR doesn't rely on received ICMP (it neither receives them AFAIK). - If the gateway is down there will be not a ICMP message (neither if the gateway TCP/IP stack doesn't generate such ICMP notifications). So with the current TM design an UDP transport error just can cause a local 408, and never a 503. This is the main problem. Unfortunatelly such 408 is painful as the examples above show. This is the reason I propose TM to generate a local 503 if no response at all is received for a UDP requests (when fr_timer expires). More or less the same info in this report: http://sip-router.org/tracker/index.php?do=details&task_id=55 Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

more fixups in mod_fix.h or what?

by jh＠tutpro.com

what is the best practice of fixing up module functions with more than two params? in mod_fix.h there is some three param fixups defined, but not all possible param type combinations. also, adding four param fixups will not scale, since the number or possible type combinations would be too large. -- juha

git:master: modules/registrar Added default_expires_range parameter, which specifies randomisation of the Expire parameter

This new parameters adds the posibility to randomize the Expiry parameter in a certain interval, (+- default_expires_range%*default_expires). This is helpful to avoid syncronization of re-registration of the UACs after an outage. Parameter is configurable via ser cfg framework. Old behaviour (fixed default_registrar value), is enabled by default, by leaving the parameter 0. --- modules_k/registrar/README | 271 +++++++++++++++------------ modules_k/registrar/config.c | 10 +- modules_k/registrar/config.h | 3 +- modules_k/registrar/doc/registrar_admin.xml | 28 +++ modules_k/registrar/reg_mod.c | 46 +++-- modules_k/registrar/sip_msg.c | 26 ++- 6 files changed, 228 insertions(+), 156 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=448…
