[Serusers] TLS: status, CVS, updates ...

by Cesc Santasusana

Hi, I have tested the free-tls code. It compiles and it works. I've tried with the minisip user agent connecting over TLS, and no major problems. Also, the interconnection of SER proxies (t_relay_to_tls between proxies, to force tls) also works. It seems to me as a rather functional piece of code, much wanted by the community, though it has not made its way through into the CVS. Why? I think it is time. This said, it also has some things that need to be fixed. I recently sent an email to peter and ser-dev ... but just got silence back. Anyway, here's the email, for those who came up with the same problems: sessioin resuming not supported (but unconfigured) by ser, and no peer certificate verification. Cesc >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >I found what i think it is a bug. I was testing with minisip, which supports TLS completely on the client side (even client certs, >incoming connections, etc). It would create the initial connection ok to SER.

[Serusers] Call routing

by Edgardo O. Gonzales II

Any feedback from ser gurus.. ======================= Hi! I was able to install and make a call successfully. However, Im using number, for example 2222 as my login name and that will serve as my termination / extension number also. How can I define a specific or corresponding extension number to a specific user. for example, I use somebody as login name and I set 1111 as his extension number. With this information, I should able to login / register to my gatekeeper and using somebody as login name and my friends can call me using my 1111 voip number. Please help me if there something I need to modify on my ser.cfg Also I want to enable accounting. Please help.. thanks, ed

[Serusers] Can SER location module work with Berkeley DB ?

by PHAN, Quang-Minh (Docteur Ordinateur)

Hi List, Is there a way to use SER with Berkeley DB for location module? I heard that Berkeley DB is ideal for location service and is better than MySQL when the location table is updated very frequently. Regards, Minh

[Serusers] LCR-module extension for GW prefixes

by Andreas Granig

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
