FreeSWITCH Infrastructure / Happy Holidays!
by Brian West 16 Dec '08

16 Dec '08

FreeSWITCers, As the project grows I felt the need for the project to own the critical infrastructure hosting things like SVN, Jira, Fisheye and various other things we as a project use. I have personally paid for two servers that Bandwidth.com is going to be colocating for the project in their data center. Teliax paid for and shipped me the two 3ware raid1 cards for the machines which was a great help. The servers are going into production after the first of the year and in the process we are rebuilding everything to allow for single sign on for every service on the FreeSWITCH project. The servers are in the hands of bandwidth.com to be racked up so we can start deployment, as you can see we have our work cut out for us with the integration and rebuild of our entire infrastructure. ;) If you wish to pitch in my personal paypal is brian(a)freeswitch.org or you can use chipin http://www.chipin.com/contribute/id/ddc094318ae5ab5b I would like to thank Bandwidth.com and Teliax for their support... I hope others will help out! Also we have another sounds order going in sometime near the end of January so any money that exceeds the server cost will go to that. The sound order I placed monday will be in this Friday. Happy Holidays and wish you the best for 2009! Thanks, Brian West FreeSWITCH

I have also been building with Release mode and discovered the uninitialized anomally to - also wondered why it only shows in Release.

windows release build

[POST-1.0.2][RFC][PATCH 0/2] Fine-grained logging: per-session logging
by stkn＠freeswitch.org 15 Dec '08

15 Dec '08

Hi, the following series of patches adds a per-session logging capability (patch 1) and converts a part of mod_sofia over to use the new functions as an example (patch 2). Note: This is one of two possible ways to implement the feature... (see below) Why?: Some of "us" are running fs with high call volumes and turning on debugging globally causes massive amounts of space used and reduced performance. This patch extends the logging api to be able to change the log level for e.g. a single session (either from the dialplan or via API command / C API) for diagnosing problems. How?: The core patch adds a couple of new functions: switch_core_session_log_printf(switch_core_session_t *, ...) switch_core_session_set_loglevel() switch_core_session_get_loglevel() A new API command "uuid_loglevel <uuid> <level>" (mod_commands.c) and a dialplan app "session_loglevel" (mod_dptools.c part of the core patch) are included. The default loglevel of a session is the current global log level. All instances of switch_log_printf() that log session-specific messages need to be converted to the new log function for this to be useful! (The second patch has the changes for mod_sofia.c) Alternative implementation: There's a second way to implement this feature, without adding another log_printf function: switch_log_printf has a "userdata" parameter that is currently unused, which could be used to pass an additional value (e.g. a session) by adding additional SWITCH_*_LOG helper macros. A session log call could look like this: switch_log_printf(SWITCH_SESSION_LOG(session), SWITCH_LOG_DEBUG, "I'm a session debug message\n"); Pro: - Can be extended for other type of log actions (e.g. if we want to implement even more fine-grained logging, per-module etc.) without adding more switch_*_log_printf functions Con: - More work for switch_log_printf() Now it's up to you to discuss which way we want to go and if this feature is deemed useful :P Stefan P.S.: The patches are available via http too: http://oss.axsentis.de/people/stkn/freeswitch/fs-r10758-session_loglevel.pa… http://oss.axsentis.de/people/stkn/freeswitch/fs-r10758-session_loglevel-co… Diffstat of the core patch: include/private/switch_core_pvt.h | 1 include/switch_core.h | 15 ++++++++++ include/switch_log.h | 18 +++++++++++++ mod/applications/mod_commands/mod_commands.c | 37 +++++++++++++++++++++++++++ mod/applications/mod_dptools/mod_dptools.c | 19 +++++++++++++ switch_core_session.c | 15 ++++++++++ switch_log.c | 34 ++++++++++++++++++++---- 7 files changed, 133 insertions(+), 6 deletions(-) -- Stefan Knoblich Systemadministrator axsentis GmbH Eupener Strasse 74 50933 Köln Tel: 0180 - 506 705 521* Fax: 0180 - 506 705 529* E-Mail: s.knoblich(a)axsentis.de Web: www.axsentis.de Eingetragen beim AG Köln: HR B 56238 UST-ID: DE244977565 Gesellschafter-Geschäftsführer: Yan Lecomte, Eduard Schlein, Apostolos Varsamis *14ct/min aus dem Festnetz der T-Com | dtms

Implicit pause during recording
by Robert Clayton 14 Dec '08

14 Dec '08

All, I was thinking since there is no direct functionality for the person being recorded to pause the recording could this be done indirectly. For example if using the functionality to record only when voice is present could the audio stream be preprocessed to evaluate the dtmf where if a specific key was pressed the audio stream would no longer be passed or passed as blank to the recording functionality so an implicit pause would be created. And when the person recording wished to continue pressing a key would signal FS to pass the audio again therefore reestablishing recording to the same file? Bob

Compiling on NetBSD
by Michael Taylor 13 Dec '08

13 Dec '08

Hi, I am using FreeSwitch on NetBSD. Some changes where needed to get FS to compile on NetBSD, these changes have been documented by Jesse and I at: http://wiki.freeswitch.org/wiki/NetBSD My question is: What is the best way to get these changes commited into the repository? My guesses are: - submit bug reports - request a subversion branch I understand that certain checks/processes will need to be done before changes will get committed to the trunk. Can you give me an overview of these processes? As part of the processes to get commits into trunk, what actions can I take to make this easier? i.e. I plan to setup some additional testing machines with non-NetBSD so that changes I make for NetBSD can be checked that they do not break other OSs.

Shared voicemail boxes
by Michael Taylor 13 Dec '08

13 Dec '08

Hi, I have an interest in setting up FreeSwitch in a small office where there is only one voicemail box shared by many distinct extensions. I am aware of how I can modify the standard dialplan logic so that the voicemail application is always given a specific mailbox number regardless of which extension is dialed. My question is: How do I get the MWI on different SIP extensions to all show the status of the single mailbox. Lets setup an example, we have the following simplified directory <user id="200" mailbox="200"/> <user id="201" mailbox="200"/> <user id="202" mailbox="200"/> i.e. the intention is for all voicemail to be stored in box number 200 regardless of what extension was called. currently a SIP phone registered on extension 202 will be notified of mail in box 202 (the registered extension). My 2nd question: What is the intended use mailbox="" in a <user> definition? switch_xml_locate_user() has the ability to locate a user by their mailbox number, but that would infer that each user would have a distinct mailbox number (because the function only returns the first user it finds with that number). If I was to define how I would want the the mailbox="" value to work, it would be: A user in the directory as <user id="202" mailbox="200"> would represent that: a) if you told the voicemail application to record voicemail for user 202 then it would store it in the box number 200. b) Later when user 202 requests MWI status, the voicemail module would lookup the box number 200. c) When user 202 wants to listen to their messages, they get directed to box number 200. a) and c) can be implemented in the dialplan with no coding. b) would need work in mod_voicemail in its processing of the event MESSAGE_QUERY If this suggested feature is appropriate then a), b) and c) should all be done in code so that the default dialplan does not need to be changed, and it is up to the directory contents as to whether mailboxes are shared or not.

Issue around IPv6
by Tamas 07 Dec '08

07 Dec '08

Hello, My original issue was that after some time (unable to find a rule when) registering gateway stopped suddenly working and went to status DOWN and state was FAIL_WAIT. In the logs I saw that it was trying to register continuously, but there were no REGISTER packet sent out anymore. Clients registering to this box were able to register, just it was not able to register to the upstream box (FreeSWITCH too). Registering scheme: clients--->FS local---(NAT)--->FS public When I've caught such a case again, I was stracing FS processes and found this: stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2393, ...}) = 0 futex(0x2ac3092ead94, 0x85 /* FUTEX_??? */, 1) = 1 futex(0x2ac3092ead40, 0x81 /* FUTEX_??? */, 1) = 1 socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 34 setsockopt(34, SOL_SOCKET, SO_BROADCAST, [1], 4) = 0 connect(34, {sa_family=AF_INET, sin_port=htons(4242), sin_addr=inet_addr("82.45.148.209")}, 16) = 0 getsockname(34, {sa_family=AF_INET, sin_port=htons(32824), sin_addr=inet_addr("192.168.1.38")}, [1451698946064]) = 0 close(34) = 0 socket(PF_INET6, SOCK_DGRAM, IPPROTO_IP) = 34 connect(34, {sa_family=AF_INET6, sin6_port=htons(4242), inet_pton(AF_INET6, "2001:503:ba3e::2:30", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 ENETUNREACH (Network is unreachable) close(34) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2393, ...}) = 0 futex(0x2ac3092ead94, 0x85 /* FUTEX_??? */, 1) = 1 futex(0x2ac3092ead40, 0x81 /* FUTEX_??? */, 1) = 1 >From this I guess, my issue relates to IPv6. That is right that the box has IPv6 address on the eth interface (ubuntu default), but this has worked for some days or some hours (varies) without this issue. So something might happen for which FS suddenly started using the IPv6 interface address (which is not configured well). I've found tha given public IP (82.45.148.209) in switch_find_local_ip function and have found that this is a root DNS server and the role of this function is to find the local IP address. As I was looking for the source, probably something sent wrong family to this function (AF_INET6 in place of AF_INET). Maybe this is a trivial issue for the experts... I'm sure that if I remove the ipv6 things from my system it will be OK, however I had similar issue on a box with no ipv6 address to. I'm not sure if it is the same/similar issue or not, but the symptoms looks similar. Unfortunately we had to restart that box (production) and since that the problem disappeared (that was maybe fixed - the case happened about 2 weeks ago). I think some users - mainly on test systems like I have - might face to this issue so it might be worth to take a look, why had FS suddenly tried to send packets on ivp6. This could be a system issue too - something crazy with Xen or Ubuntu? Thanks in advance! Regards, Tamas ps: FreeSwitch Version 1.0.trunk (10567M) Ubuntu Hoary (8.04) under Xen
