ZRTP
by Robert Clayton 05 Aug '08

05 Aug '08

Is anyone attempting to implement the ZRTP cryptographic key-agreement protocol (a method of encrypting voice data using self-generated keys, rather than keys from certificate authorities). Some softphones such as X-Lite already implement it. There is apparently an open source library at ftp://ftp.gnu.org/gnu/ccrtp/libzrtpcpp-0.9.0.tar.gz

ISSUES: webapi with iPhone, expr divide by zero
by Michael Collins 01 Aug '08

01 Aug '08

FYI, I stumbled across two potential issues. I'm sure if we don't deal with them then some overzealous security "expert" is going to flag these as vulnerabilities. First off, expr probably needs some error checking. If you go to the CLI and type "expr 1/0" then your system will lock up. I had to kill -9 the pid to get it to clear out. I don't expect normal people to attempt to divide by zero but we might as well not leave a potential DoS hole open. (Let me know if you want a jira on this issue.) Secondly, I am consistently able to get fs to crash when accessing an api or webapi command via the abyss/xmlrpc server. In the latest instance it crashed as soon as I connected to the server itself, but at least twice I was able to connect to the server but it core dumped as soon as I did any kind of api/webapi command. I have core dumps and I'll bt full them and get a jira open on this as well. I just wanted to alert you guys in case you are curious. It's almost 3am here so I'm not awake enough to make a coherent jira post atm. I have tested the api/webapi with Safari on WinXP and Safari on OSX Leopard with no issues. I'm pasting the bt full at the end of this email but I will include it also in the jira that I open up... -MC bt full #0 0x0072bfd3 in strlen () from /lib/libc.so.6 No symbol table info available. #1 0x0072bd15 in strdup () from /lib/libc.so.6 No symbol table info available. #2 0x002673ab in TableAdd (t=0x0, name=0x292db0 "freeswitch-user", value=0x0) at ../../../../libs/xmlrpc-c/lib/abyss/src/data.c:497 No locals. #3 0x0026fa7e in ResponseAddField (sessionP=0xbe82a8, name=0x292db0 "freeswitch-user", value=0x0) at ../../../../libs/xmlrpc-c/lib/abyss/src/response.c:131 No locals. #4 0x00263b12 in http_directory_auth (r=0xbe82a8, domain_name=0x87bbd58 "192.168.50.229") at mod_xml_rpc.c:310 p = 0x87446a6 "dW5kZWZpbmVkOnVuZGVmaW5lZA==" x = <value optimized out> z = "freeswitch:works\000\201¾\000tch\"", '\0' <repeats 36 times>, "\001", '\0' <repeats 19 times>, "\001h)\000\002\000\000\000\000\000\000\000ÿÿÿÿ\000\000\000\000\200³\177\000h\213}\b\000\000\000\000\000\000\000\000\n\000\000\000\001\000\000\000\206\f~", '\0' <repeats 29 times>, " z¾\000\000\001\000\000\001\000\000\000\001", '\0' <repeats 15 times>, "±[r", '\0' <repeats 29 times>, "±[r\000¸Á\177\000QSr\000PÁ\177\000PÁ\177\0002048\000\000\0001\000\000\000\000(\000\000\000¨Å|\b" t = "ZnJlZXN3aXRjaDp3b3Jrcw==\000\000\000\0000Á\177\000\200\000\000\000\---Type <return> to continue, or q <return> to quit--- 030\000\000\000¼$~\000@#y\bQSr\000PÁ\177\000PÁ\17711456ô¯\177\000QSr\000\030\000\000\000,Á\177" user = "undefined\000undefined", '\0' <repeats 489 times>, "d\000\000" mypass1 = 0x0 mypass2 = 0x0 x_domain = (switch_xml_t) 0x86c4990 x_domain_root = (switch_xml_t) 0x86a9df8 x_user = (switch_xml_t) 0x0 x_params = <value optimized out> x_param = (switch_xml_t) 0x0 box = 0x221d72 "" at = 0 params = (switch_event_t *) 0x0 __PRETTY_FUNCTION__ = "http_directory_auth" #5 0x002644ca in auth_hook (r=0xbe82a8) at mod_xml_rpc.c:389 new_uri = <value optimized out> tmp = "°cy\b Á\177\000\021\000\000\000i\000\000\000\021\000\000\000PÁ\177\000Q\000\000\000Xcy\bh\000\000\000ð¼{\b\020\000\000\000ð¼{\b±[r\000ô¯\177\000`cy\b Á\177\000\220Ò\203\000\004\201¾\000\000\000\000\000\000\000\000\000L\000\000\000ÈÁ\177\000±[r\000¤\037r\000PÁ\177\000Xcy\b±[r\000\236 {\bÈ\000\000\000\000\000\000\000\210\232m\b¡z¾\000\003\000\000\000+\202p\000±[r\000PÂ\177\000W\201¾\000PÁ\177\000\030\000\000\000,Á\177\000QSr\000Ø\201¾\000\030\000\000\000,Á\177\000PÁ\177\000\000\000\000\000\002\000\000\000\226 {\bQSr\000\226 {\b"... ---Type <return> to continue, or q <return> to quit--- list = {0x292f61 "index.html", 0x292f6c "index.txt"} domain_name = <value optimized out> ret = 0 __PRETTY_FUNCTION__ = "auth_hook" #6 0x00270939 in serverFunc (userHandle=0x87ba058) at ../../../../libs/xmlrpc-c/lib/abyss/src/server.c:515 handlerP = <value optimized out> srvP = (struct _TServer * const) 0x885ed68 requestCount = 1 #7 0x00266450 in connJob (userHandle=0x87ba058) at ../../../../libs/xmlrpc-c/lib/abyss/src/conn.c:37 No locals. #8 0x00274a32 in pthreadStart (arg=0x87bcb58) at ../../../../libs/xmlrpc-c/lib/abyss/src/thread_pthread.c:48 __cancel_buf = {__cancel_jmp_buf = {{__cancel_jmp_buf = {2759784, 0, 12487568, 12485560, 325792842, 334691634}, __mask_was_saved = 0}}, __pad = {0xbe8470, 0x0, 0x0, 0x7faff4}} __cancel_routine = (void (*)(void *)) 0x266480 <threadDone> __cancel_arg = (void *) 0x87ba058 not_first_call = <value optimized out> threadP = (struct abyss_thread * const) 0x87bcb58 #9 0x0083545b in start_thread () from /lib/libpthread.so.0 No symbol table info available. ---Type <return> to continue, or q <return> to quit--- #10 0x0078d24e in clone () from /lib/libc.so.6 No symbol table info available.

.NET Development
by Patrick Tran 31 Jul '08

31 Jul '08

I'm new to Freeswitch and trying to develop a .NET Application. I'm having a lot of trouble getting started though. There doesn't seem to be a lot support out there for this. My development has sort of come to a stand-still and I was wondering if anyone could help me get pointed in the right direction. Any help would be much appreciated. Thanks -Patrick

Windows Build
by Robert Clayton 29 Jul '08

29 Jul '08

Congratulation on FreeSwitch 1.0.1. I was attempting to do a VS2008 build. The documentation for compiling under windows: http://wiki.freeswitch.org/wiki/Download_%26_Installation_Guide Suggests deletion of two files I do not find: libs/iksemel/include/config.h libs/xmlrpc/xmlrpc_config.h and changing two settings I do not see in the Property Pages: FreeSwitchCoreLib - Enable Minimal Rebuild XML Interfaces\mod_xml_rpc - Enable default libraries Would you suggest just using a different compiler?

Custom sip contact header
by Simon Capper 24 Jul '08

24 Jul '08

I need to set the contact header on a per outgoing call basis, I can't find a way to do this in the mod_sofia. Would you accept a patch for a new channel parameter "sip-contact" that gets used as the contact username in sofia_glue_do_invite when the invite_contact is not already set, i.e. Non-gateway calls. It would be similar to the " sip_transport" channel variable. Simon
