by raviprakash sunkara 06 Jun '07

06 Jun '07

Hello Users, I'm tring to configuring the load balance , Initial i have 2 sip proxies and centralized database. for 2 sip proxies database is common , ie. centralized. Let Assume the proxy1 is a.b.c.b , other proxy2 is 1.2.3.4 and proxy domain name is sip.sample.com , is common if the proxy1 is not started or some failure case , it has goes to the second proxy2.. but this is not happening at all. i follow this url for DNS_setting -- > http://www.voip-info.org/wiki/view/DNS+SRV all the request going to proxy1 only. but not the proxy2.... please any can guide me regarding this... -- Thanks &Regards Ravi Prakash Sunkara

[Users] Mediaproxy Selection for Inbound DID calls
by Mike O'Connor 06 Jun '07

06 Jun '07

Hi All I would like to be able to have a difference Mediaproxy group selected per user account on inbound DID calls. Our termination provider sends the calls to our openSER with a URI of something <number>@<IP_address>. '08723451234(a)202.xxx.xxx.xxx', we use the alias_db_lookup("dbaliases") function to resolve the phone number to a user account on the DID calls. I would think that some type of rewrite of the '@202.xxx.xxx.xxx' would need to be done but I'm sure this would cause other issues. Any ideas would be great :) Thanks Mike

[Users] Question about Processes and their priorities in OpenSER
by Ian Fedeli 06 Jun '07

06 Jun '07

Hello, I am working on trying to stress OpenSER using a benchmarking utility. I have three questions: 1) I was hoping someone here could tell me how many 'openser' processes I should expect, and what their functions are. For example, I would expect there would be one process for each child, but I find that there are more processes than children as configured in openser.cfg. I have it set to 32 children in openser.cfg, and yet I find that there are 36 processes. The only non-standard module I have configured openSER to use is the mySQL module. I have attached the output of ps auwx | grep openser below. 2) When I observe the benchmark as it is running (see below), I notice one process that seems to have a lower priority, yet take up more CPU time than the rest. Is this process special (this relates to question 1)? 3) Why is only one processor (Cpu2 in the example below) saturated? The server is running on a machine with 2 dual-core processors, for a total of 4 CPUs. I am reasonably sure my benchmark is not network limited, as the server and the client-benchmark machine are connected via 2 Gigabit NICs. I have also discovered that if I renice the process mentioned in question 2 to -20, all 4 processors become saturated, and the throughput of the server more than doubles. The output from top is below. Any insight is greatly appreciated. Thanks, --Ian Fedeli #ps auxw | grep openser root 27038 0.0 0.0 2150456 4536 ?

[Users] Question about forking
by Andreas Sikkema 06 Jun '07

06 Jun '07

Hi, I have SIP UA's register to my OpenSER server and they can call each other. This has been working for some time now without any real issues and I'm very happy. Now I want to be able to have 1 destination be available on 2 SIP UA's. What I think the best way to do is the following: - create two accounts - make the detination point to one UA A and create an "alias" for the destination at UA B (for instance by prefixing A) - On an incoming call detect that there is the possibility to reach the destination at A and B - Fork the incoming call to A and B so that when one arm of the fork accepts the call (by going to ringing, or immediately answering, etc). My questions are: - How do I check if I can start a fork? - How do I fork and have both arms follow the logic I am currently using? -- Andreas Sikkema

[Users] application via voip?
by Matthew Pease 06 Jun '07

06 Jun '07

Hi all - Not really sure where to post this question as I am just starting to research this issue. We'd like an all VOIP solution where we have a telephone number that terminates at our server. At our server, we'd like to: 1. get their phone number via caller ID. look up data with the caller id. 2. generate a wave file based on the data returned & play it to the user over the established voip link. How is this done? Totally new to the game here. I've read about DID origination, SIP channels, SIP peers... its all quite confusing! I'm a java developer, so something that works via Java would be great, but scripting in various languages is no big deal. The application doesn't need to do much more than query a database & choose a WAV file to play back based on that info. Thank you-- Matt Pease ParkingHero, Inc.

I'd like to use the address where the SIP request came in for both RTP streams. Maybe I can use the pseudo-variable $Ri (Received IP address) as the second parameter to force_rtp_proxy? This should force the use of the correct IP address in the "c=" field and will hopefully persuade the client to use this IP address as the destination address for its RTP data.
