FreeSwitch and simple encryption
by Dmitry Mordovin 04 Feb '11

04 Feb '11

Hello, I wish to implement some simple encryption stuff into FS. My Idea: Imagine, some clients who have SIP softphone with encryption (My own method and only SIP signaling packets will affected) will interconnect with FS. So, FS must decrypt this packets before proceed it and encrypt before sent to this client. Could anyone direct me to easy way to implement it? Thanks Dmitry

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.

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

Well, it's that time again. The FreeSWITCH developers are gathering at a secret location in Wisconsin next week and the community is invited to participate in this year's "buy the devs dinner" event. How to do it: Go to freeswitch.org and click on the Paypal link. Toss a few bucks in the hat and send along your bon apetit message. If for some reason you cannot use Paypal but still wish to participate then by all means call Brian West on his SIP phone: 2000(a)bkw.org. (Hint: you can dial 9191 if you have a default FreeSWITCH config.) Brian is well-prepared to take your money. :) To those who have donated recently we say, "Thank you!" If you wish to donate again specifically for this occasion you are more than welcome to do so. In any case, thank you in advance for your generosity. You are great community members and the FreeSWITCH team is absolutely glad to have you with us! -Michael Collins

Freeswitch on ARM, Memory alignment issues
by M D 28 Jan '11

28 Jan '11

Summary: Has anyone looked at/actively looking at the 32-bit boundary memory alignment requirement for the ARM architecture? Detail: I am running freeswitch on an ARM platform (dockstar based on Marvell Kirkwood). I have compiled and tested both freeswitch-1.0.6 and freeswitch-head(1,2), and found that stun lookups were failing with a "Timeout" error. Debugging the issue points to memory alignment issues specific to the ARM architecture. Basically, due to the fact that the uint8_t array "buf", is not aligned at a 32-bit memory boundary, the stun lookup packet sent to the stun server was malformed. Web searches confirm that a symptom of misaligned access on ARM is an apparent memory corruption. This can be fixed by forcing alignment of specific variables to 32-bit boundary. As an example, in the switch_stun_lookup function of file src/switch_stun.c , we currently have { switch_sockaddr_t *local_addr = NULL, *remote_addr = NULL, *from_addr = NULL; switch_socket_t *sock = NULL; uint8_t buf[260] = { 0 }; .... } If I change it to { switch_sockaddr_t *local_addr = NULL, *remote_addr = NULL, *from_addr = NULL; switch_socket_t *sock = NULL; uint8_t buf[260] __attribute__ (aligned(4)) = { 0 }; .... } or { switch_sockaddr_t *local_addr = NULL, *remote_addr = NULL, *from_addr = NULL; switch_socket_t *sock = NULL; uint8_t *buf; buf = (uint8_t*) malloc(sizeof(uint8_t)*260); .... } the stun lookup packet sent is correct.freeswitch is also able to parse the recvd packet and correctly determines the external IP. Random crashes coupled with looking at the code in switch_rtp suggests that the memory alignment issue may not be limited to this function or even this file. Has anyone looked at ARM memory alignment issues for freeswitch in general? cheers, -m (1) Current head leads to the situation where call gets connected but there is no-audio. I have not had the chance to debug this, but suspect this could be due to the "eat rtp .... " patch combined with ARM memory alignment issues. (2) The tested (audio working, some issues) git version is commit 715d250e171a94736b19019ac742f739899ad997 Author: Mathieu Parent <math.parent(a)gmail.com> Date: Wed Dec 15 21:29:52 2010 +0100

fsctl pause
by Bernhard Suttner 27 Jan '11

27 Jan '11

Hi, if I use "fsctl pause" freeswitch should not handle any new call but a INVITE will still be send answered from FreeSWITCH with 407 Proxy Authentication Required. This message go back to the peer. If the peer then send the INVITE with credentials (with authentication) FreeSWITCH sends bacck the 503 "No more sessions" because of the "pause state". Shouldn´t freeswitch respond with 503 for the first INVITE and not only for the second INVITE with authentication? Best regards, Bernhard

the odd numbers are not tagged in GIT. Even numbers are. Expect 1.0.8 in a month or so. /b On Jan 16, 2011, at 4:48 PM, Jason White wrote: > A minor point: the 1.0.7 release doesn't appear to have been tagged in > the Git repository.
