[Freeswitch-dev] ANNOUNCEMENT CudaTel IP PBX (powered by FreeSWITCH) Reaches Critical Mass
by Anthony Minessale 04 Feb '11

04 Feb '11

I have been splitting my time developing not only FreeSWITCH but the CudaTel Phone system by Barracuda Networks that uses FreeSWITCH as the telephony engine. I'm proud to announce that not only has the product reached a 2.0 status, it's now 100% deployed within Barracuda Networks running the entire company's phone services across multiple locations. The CudaTel is using FreeSWITCH right from GIT with no special modifications at all. The best part is it works great as a PBX you can then feed out to your existing FreeSWITCH setup to route the traffic to custom applications or whatever you can think of. The next step is to develop more exciting and impressive PBX features that can be added for free with an energize update package available at the time of purchase. CudaTel comes with the same great support you receive today on FreeSWITCH. This is also a great opportunity for those of your out there looking to get into the reseller market. Contact me at the consulting link at the top of this page or call 408-588-3633 to learn how you can become a reseller of CudaTel. Use your existing VoIP expertise to support and deploy CudaTel to others.

[Freeswitch-dev] Switch_core_get_variable
by Kevin Snow 03 Feb '11

03 Feb '11

I found a hole in the way we handle core variables in FS. Switch_core_get_variable does the lookup and returns the found pointer. In Switch_core_set_variable the first step it does is look up the variable and free it (if it exists). This would free it out from under another that has just done a get on it. This is how I stumbled on this. Is the right fix is to add a switch_core_get_variable_dup that dups the string while in the mutex protection? I realize in the core case this will require the caller to then free the returned memory, but this is better than getting a bad pointer. This is analogous to the switch_channel_get_variable and it¹s _dup implementation, although it dups it to session memory. Switch_channel_get_variable¹s ability to peak through to the core variables is susceptible to this. If a core variable is changed after switch_channel_get_variable looks it up but before it dups to the session pool, it¹ll have a bad pointer. Kevin Snow Ooma, Inc
