Thanks Samuel, I think the dispatcher module does not acomplish my requeriments for now. I more interested now in the avpops module. I read some lines about the module a few months ago for a similar problem. Is someone using this module for something like this?. In particular i want to mantain a route table for all my destinations and the respective terminating gateway. For example : Code Gateway 56 | 192.168.0.1 1 | 192.168.0.2 44 | 192.168.0.3 and so on.... This table is consulted for all the incoming request and then SER answer with a Redirect for the particular GW. Can someone provide me and example on how the AVPOPS module can handle this? I will really appreciate.... Thanks in advance Best Regards.

Hi, There are a couple of modules in version 0.9 which can be used for dynamic routing depending on the desired functinality. One is called dispatcher, and is meant to be a load balancer without fair distribution. I think that you define a list of possible servers in a database and the dispatcher module forwards message to one of them (together with all within-dialog future responses and requests). The other option is to use avpops module which provides an attribute-value functionallity. You can use them to select the next hop depending on the incoming SIP message parameters and the values present in a database. I would advise you to take a look at the documentation of both modules to see if they suit your requirements before using the exec commands, which are not 100% reliable and increases the memory requirements as you have mentioned. From the exec module's readme: 1.5. Known Issues There is currently no guarantee that scripts ever return and stop blocking SIP server. (There is kill.c but it is not used along with the current mechanisms based on popen. Besides that kill.c is ugly). Enjoy SER, Samuel. Unclassified. Darren: Thanks for your quick answer. I was thinking in a similar solution, using a external program, in fact i use the exec_dset() functionality for something similar. I was thinking add to this solution a Redirect Server?. Maybe the call to the dynamic route proccess is in the Redirect Server, calling the exec_dset() function, so all the extra resource needed to perform these tasks are used in the redirect server and no in my Proxy-Registrar Server. Is just an idea.. IS this scalable maybe? Is this posible? Thanks in advance Best Regards, Ricardo Martinez.- -----Mensaje original----- De: Darren Nay [mailto:dnay@ionosphere.net] Enviado el: Lunes, 10 de Enero de 2005 11:06 Para: Ricardo Martinez; 'serusers(a)lists.iptel.org' Asunto: Re: [Serusers] Dynamic Routes with SER. Take a look in the SER Admin guide at "Executing an External Program". You can write an application with perl, C, etc.. Which will process the call info and return a destination set. This functionality is available using the exec_dset function in SERs exec module. I use this feature in our SER deployment and it works great. The only problem I've found so far is that it definitely does increases the resources required per call, and hurts your scalability. Especially if you use perl. Try to use C if at all possible, or persistent perl at the very least.
