503 Server error response for REGISTER request (Asterisk v1.6.0.5)
by Vikram Ragukumar 04 Feb '11

04 Feb '11

Hello, I had posted this question earlier on asterisk-users, but didn't receive any reply, so I'm posting on sr-users in the hope that someone can provide guidance on how to debug this problem. Our setup involves a Sip softphone registering with a fresh install of Asterisk v1.6.0.5 through an outbound proxy (Kamailio v3.1.1). We observe that about 80% of the time, immediately after startup of the softphone, when the softphone sends a REGISTER message, Asterisk replies with a "503 Server error". However, subsequent REGISTER messages are replied to appropriately (with a 401 Unauthorized). There are very few devices (under 5) registered with Asterisk, so this is not an overload issue. Please find attached a SIP trace for device registration. - What might cause this behavior in Asterisk ? - Are there any config file parameters that require to be changed ? - Would it help to see any other specific logs, if so which ones ? Thanks and Regards, Vikram.

Hi All, Kamailio had just started to get SIP attacked and it looked like they were sending a bad header and Kamailio died..

Reloading a module without restart
by Stagg Shelton 04 Feb '11

Is it possible to reload a module such as siptrace without requiring a full restart of kamailio. I have changed my db_url modparam for the siptrace module and would like to avoid restarting kamailio if possible. Thanks Stagg

Redundancy between 2 Kamailio servers
by Danny Dias 02 Feb '11

02 Feb '11

Hello my friends, I wonder if someone has done this before? i would like to implement 2 Kamailio servers with redundancy, something like the following: SERVER_A is working as the primary sip proxy (virtual IP as the sip signaling), if it fails, the other server (sleeping) should UP the virtual IP and takes all the traffic....i guess there is many Linux implementations thah can do this, but i would like to know if there is someone that has done this before and hear some recomendations... I've read some difficulty in the synchronisation of registrations because Kamailio works best when it stores registrations in memory and registrations are constantly changing - they expire and are renewed, as well as new ones joining and old ones leaving. To make the failover solution function seamlessly, it is necessary to synchronise the in-memory registrations between the primary and the backup server . This can be done by forking a copy of the registration request to the backup server, but there are some practical problems in doing this, has anyone do something with this? Thanks in advance!

Weird IPv6 Registration Issue
by Jon Farmer 02 Feb '11

02 Feb '11

Hi I am experimenting with a dual homed (IPv4 and IPv6) Openser 1.1.0-tls server. If I register using a IPv6 address then the initial registration works and the details are saved in the location table. However when the UA trys to re-register on expiry the SIP returns a 200 OK but the location data is not updated in the table. Looking at the syslog it is reporting that it didn't save the data as there was an existing entry on index with key 1. This is referring I presume to the primary index on "username, domain, contact) on the location table. So what happens is the first location entry expires and gets deleted from the table and thus there is no record for the subsequent register and thus openser thinks the UA has dropped off until the next re-register when because there is no longer a location record the data gets saved correctly. This doesn't happen if I register the same UA on IPv4 on the same openser server. Anyone got any ideas why this is happening?

Hi, just to be sure: - If the gateway does send back a 100 Trying and then a 408 is detected within failure_route the method t_branch_replied does return false (means: gateway is up and running) - dont go to next gateway (dispatcher) - If the gateway does not respond and a 408 is detected within failure_route (= 408 was generated from kamailio) t_branch_replied does return true (means: gateway is down) - go to the next gateway (dispatcher) Is that correct or am I wrong?
