[Serusers] Newbie question about multi-tenant and IVR/Asterisk Integration
by lists＠infoway.net 15 Jun '07

15 Jun '07

Hi all, I'm relatively new to SER. I've been using Asterisk for a few years and am now trying to figure out how to move to SER and/or SER/Asterisk architecture. We offer our clients (small offices) VoIP telephony services. As such, we offer them autoattendants, IVR, voicemail, and other services common to small businesses. In Asterisk, we play with contexts in order to allow Office A to have extensions 101 thru 105 and Office B to have extensions 101 thru 110, such that when Office A dials from 101 to 103, it only rings within the Office A "space" and restricts visibility among the different offices. So, the first question I have is how to achieve this in SER? Since the only protocol we deal with is SIP, we figured we could reduce our use of Asterisk to the extreme minimal and try to do as much as we can in SER. So, probably, we would end up with Asterisk for autoattendant, IVR, and possibly voicemail as well (depending on how we can use SEMS). Now, the second question I have is. When a call comes into an office and an autoattendant answers (which is basically sort of like an IVR script), we want SER to send the call to Asterisk for the IVR script to handle it. However, when the caller makes a selection, say they press 110 to dial extension 110, we want Asterisk to send the call back to SER and tell it to transfer the caller to extension 110 and then Asterisk will stay out of the way (media). Is this possible? Can anyone provide any pointers on how to achieve these issues in SER, SER/SEMS, SER/Asterisk, and/or SER/Asterisk/SEMS? Thanks

[Users] MediaProxy and SDP Multipart
by Edson 15 Jun '07

15 Jun '07

Hi... We are trying to use a Cisco 2600 as our IPIP-GW between our SIP and H323 networks. Until a week or so the comunications were working so-so, but from a week it stops completely. Digging on the problem, I found MediaProxy messages informing that it couldn't handle the SDP informations, that SDP was illegal... Looking on Google I finded that this behavior was reported as a know limitation of MediaProxy and NAThelper modules (http://lists.iptel.org/pipermail/serusers/2006-June/028981.html). Aren't this limitations resolved on Mediaproxy 1.8.2? What are our best choises? Maybe migrating to Yate? Thanks for any thoughts... Edson

[Users] Permissions Module - Table Version
by Kelvin Williams 15 Jun '07

15 Jun '07

My new OpenSER server will not load the permissions module. I built this box from source downloaded from the openser.org site three days ago (openser-1.2.1-tls_src.tar.gz), and populated my PostgreSQL database with the scripts/postgresqldb.sh script included with the source. I'm setting up permissions.so like: loadmodule "permissions.so" modparam("permissions", "db_url", "postgres://<<snip>>") modparam("permissions", "db_mode", 0) modparam("permissions", "trusted_table", "trusted") modparam("permissions", "ip_addr_col", "src_ip") modparam("permissions", "default_allow_file", "/usr/local/etc/openser/permissions.allow") modparam("permissions", "default_deny_file", "/usr/local/etc/openser/permissions.deny") When I attempt to start openser with the permissions module, I receive the following in the log: Jun 14 19:13:21 gaia /usr/local/sbin/openser[21948]: permissions - initializing Jun 14 19:13:21 gaia /usr/local/sbin/openser[21948]: Default allow file (/usr/local/etc/openser/permissions.allow) not found => empty rule set Jun 14 19:13:21 gaia /usr/local/sbin/openser[21948]: Default deny file (/usr/local/etc/openser/permissions.deny) not found => empty rule set Jun 14 19:13:21 gaia /usr/local/sbin/openser[21948]: permissions:init_addresses(): Invalid table version 2 - expected 3 Jun 14 19:13:21 gaia /usr/local/sbin/openser[21948]: Error while initializing allow_address function Jun 14 19:13:21 gaia /usr/local/sbin/openser[21948]: init_mod(): Error while initializing module permissions I have verified the table is in the database: openser=# select * from trusted; id | src_ip | proto | from_pattern | tag ----+--------+-------+--------------+----- (0 rows) I was instructed to increment the version of the table in the database, and I did using the information from the log (changing the version to 3) and still received the same error. The version table had the following for trusted when it was installed (from script): openser=# select * from version where table_name = 'trusted'; table_name | table_version ------------+--------------- trusted | 4 (1 row) Any light that someone could shed on this for me would be greatly appreciated. Many thanks, Kw

[Serusers] Call waiting and accounting
by inge 15 Jun '07

15 Jun '07

Hi all, I've got a problem with call waiting function. This one allow us to hang out a call when we are already in communication. But when I press "R" on my phone to take the second call, there is one INVITE and one ACK generated by the proxy and being accounted in MySQL. It's the same when I switch between both callers. So I can have for the same callid 2 3 4...X INVITE ACK and one BYE. So in SERWeb for example, I can see for one call 3 lines of accounting. Thanks for you support. Adrien .L
