[Serusers] SER x Nextone problem
by Rodrigo P. Telles 26 Apr '05

26 Apr '05

Hi guys, I've been experiencing some troubles with carrier's that are using Nextone (www.nextone.com). I could place calls through Nextone but no longer then 1 minute, between 48 and 53 seconds the call is dropped with a BYE sent by Nextone. I've been using another carriers using Cisco and Quintum without problems. Does some one experimenting this problem? I'm using SER 0.8.14. Thanks in advance. -- ============================================ Rodrigo P.

[Serusers] LCR-module extension for GW prefixes
by Andreas Granig 25 Apr '05

25 Apr '05

Hi all, I've extended Juha's LCR module to support prefixes for gateways. We use it for prefix-based setting of the bearer capability on our gateways. Note that the attached patch is against Juha's backport for rel_0_9_0 at http://tutpro.com/tmp/lcr-0.9.0.tgz because we've no CVS-HEAD running here. It works as follows: In the new table gw_cap you can define capabilities and their corresponding prefix, like: mysql root@ser> select * from gw_cap; +--------+-----------+------------+----------------------+ | cap_id | cap_value | cap_prefix | cap_description | +--------+-----------+------------+----------------------+ | 1 | 1 | | default phone trunk | | 2 | 1 | 01 | prefixed phone trunk | | 3 | 2 | 02 | prefixed fax trunk | +--------+-----------+------------+----------------------+ 3 rows in set (0.00 sec) In this case the cap_value of "1" means phone-capabilites, "2" means fax-capabilities. The table gw_grp is extended with an additional column cap_id. mysql root@ser> select * from gw_grp; +--------+-------------------------+--------+ | grp_id | grp_name | cap_id | +--------+-------------------------+--------+ | 1 | priority_1_phone | 1 | | 2 | priority_1_phone_prefix | 2 | | 3 | priority_1_fax_prefix | 3 | | 4 | priority_2_phone | 1 | | 5 | priority_2_phone_prefix | 2 | | 6 | priority_3_phone_prefix | 2 | +--------+-------------------------+--------+ 6 rows in set (0.00 sec) In ser.cfg you can then load the gateways for example like this if you use different gateways/trunks for phone and fax: if( /* phone call */) { if(!load_gws("1")) { sl_send_reply("500", "Internal server error, unable to load phone gateways"); break; } } else /* fax call */ { if(!load_gws("2")) { sl_send_reply("500", "Internal server error, unable to load fax gateways"); break; } } The usage of next_gw() is as usual. Also note that the gateway selection algorithm changes when you use load_gws("x") instead of load_gws(): The latter always selects the gateways with highest priority first. The new one uses the priority value as weight, so also gateways with lower priority are chosen. Hit ratio for 5000 rounds is as follows: priority-1-gw-1: 35% priority-2-gw-1: 14% priority-2-gw-3: 14% priority-2-gw-2: 14% priority-2-gw-4: 14% priority-3-gw-1: 9% Looking forward for comments/fixes/improvements, Andy

Hi, I'm using eyebeam and xten lite with a Fedora core 3 and ser-0.9.1 from csv... The ser server in main office serving branch offices connected with frame relay 64kb.

[Serusers] rtpproxy locks up ser
by Richard 09 Apr '05

09 Apr '05

Hi, I don't know if anyone has experienced this. The ser stops getting any packets, ser log shows no activity. When I do "netstat -an", I got this, Proto Recv-Q Send-Q Local Address Foreign Address State udp 261580 0 80.1.2.3:5060 0.0.0.0:* udp 85224 0 0.0.0.0:35940 0.0.0.0:* udp 0 0 0.0.0.0:35941 0.0.0.0:* udp 47704 0 0.0.0.0:35942 0.0.0.0:* udp 0 0 0.0.0.0:35943 0.0.0.0:* I restarted ser several times, didn't help. So I restarted rtpproxy. Ser started processing packets and the recv-q drops to 0. I wonder what could cause recv-Q accumulating packets. Everything was running fine without any problem for a long time. I haven't made any change to either ser or rtpproxy recently. Any suggestions? Thanks, Richard

[Serusers] SER Reliability
by Ricardo Martinez 04 Apr '05

04 Apr '05

Hello list. I have a question about reliability in SER. Suppose that for certain reason, the process "ser" fails, and therefore the SIP Server is down. Is there a way to keep trace of the "ser" process status?? and if the process is not running start a script to restart the process. I know that maybe the "crond" command could be useful for this purpose. Does someone have any clue about this? Or maybe SER has his own "crond" module or something.? I really need and advice about this issue. Thanks in advance Regards, Ricardo Martinez Ogalde.-
