Profile configuration and aliases

19 Jun '08

Hello Question 1: I got the following config: Name Type Data State ================================================================================================= outbound profile sip:mod_sofia@MY.PUBLIC.IP:5080 RUNNING (0) nat profile sip:mod_sofia@MY.PUBLIC.IP:5060 RUNNING (0) default profile sip:mod_sofia@192.168.1.124:5070 RUNNING (0) mydomain.com alias default ALIASED ================================================================================================= 3 profiles 1 alias I can't user "originate sofia/default/auser 8888", I get "Cannot locate registered user auser@default". It works if I use "originate sofia/mydomain.com/auser 8888". Shouldn't both work? -------------------------- Question 2: Isn't this valid? <X-PRE-PROCESS cmd="set" data="domain=$${local_ip_v4}"/> <X-PRE-PROCESS cmd="set" data="sip_profile=mydomain.com"/> If not, please change the description: "sip_profile: Must be a domain name if you are being a registry server; otherwise can be any string." It produces the following config: Name Type Data State ================================================================================================= outbound profile sip:mod_sofia@MY.PUBLIC.IP:5080 RUNNING (0) nat profile sip:mod_sofia@MY.PUBLIC.IP:5060 RUNNING (0) default profile sip:mod_sofia@192.168.1.124:5070 RUNNING (0) 192.168.1.124 alias default ALIASED ================================================================================================= 3 profiles 1 alias User's cant register using mydomain.com as domain. I tried by adding $${sip_profile} as an alias for the default profile, but that didn't help. -------------------------------- Regards, Jonas

Brian, I have a lab environment that can generate 40,000 calls per hour over dual T1. I can also test analog trunks with caller ID up to 8 ports with about 6,000 calls per hour.

As you said, your driver name doesnt match any of the names I used to detect if it's firebird. The problem is that most databases supports "SELECT 1" as a query. It will always be successful if the the connection is up. However, firebird did not support "SELECT 1" and therefore i did query the system database instead. If the firebird check fails, it will try to invoke "SELECT 1", and on firebird that query will fail. And the failure is interpreted as the connection is down, and therefore it tries to reconnect. That's probably why you get that error. If you have any other idea on how I can detect if it's a firebird db, please let me know and i'll fix the odbc code.

I have since archived the project so cannot point you to the actual code. However, the problem is that it assumes the name of the Firebird Driver (FB64?) to set a boolean, so that it handle the connection test differently. When looking at the actual code, I actually felt that the connection test was redundant, as all it did was a select from a system table. This meant it was doing two queries for everyone required.

The problem was probably that the source code was compiled from the website instead of svn. Checkout the latest svn and compile that code. Everything will work just fine - it happened to me last week. Cheers Chris Mylonas (zirtron)

Re: [Freeswitch-users] Spidermonkey ODBC

Many databases break silently or the connection drops without any way to know for sure w/o trying to use it. I choose to ensure in the core that the data is connected. executing "select 1" is a small price to pay to make sure that the database is connected considering the importance of persistent connectivity in the sip, jingle and call limit databases as well as the javascript that rely on it. All of those applications to make the safe assumption that the core will keep the db connected and to change that would be drastic behavior change and destabilize the code on the eve of our release. Therefore i guess we should focus on better heuristics to detect firebird, preferably based on the driver name and not by doing a 2nd sql stmt every time.
