If the problem persists can you open a bug on jira. http://jira.freeswitch.org That way we can track it better and you can attach traces etc. That crash appears to come from the sofia sip library. there have been a few updates to that library that may not be applied to your tree can you try the following commands from your unix shell in the main root of the freeswitch src? svn update cd libs/sofia-sip make clean make cd ../.. make clean modwipe make install what does your dialplan look like that you are testing calls to?

Hi there I am quite new to FreeSWITCH and VoIP. I have been searching the net and the users-list archive, but can't seem to be able to find an answer to this question: Can I use an old fashion dialup modem to connect an ordinary phone and hook to VoIP? Any pointers, references appreciated. Thanks in advance. -z

ATTENTION: I would like to see a fully functional H323 endpoint module in FreeSWITCH before the first release... to make this do able I need to find funding so I can have someone clear the time to move forward. The guys are working very hard on the endpoint module and I thank them for the work but we need to step up dev and see if we can crank out this before release 1. Anyone willing to provide funding please find me off list ASAP and we'll talk. Thanks, Brian

mod_java build problem
by jonathan augenstine 18 Nov '07

18 Nov '07

I am trying to build the mod_java module and I am encountering a compile problem. Initially, I encountered this on OSX and chalked it off to a BSD gcc issue (I have encountered issues with BSD build problems before and yet it will build successfully on Linux). I then attempted to build on Fedora and encountered the same exact problem. The error listed is a pointer initialization issue: making all mod_java Compiling freeswitch_java.cpp... Compiling switch_swig_wrap.cpp... Compiling mod_java.c... cc1: warnings being treated as errors mod_java.c:117: warning: initialization from incompatible pointer type make[5]: *** [mod_java.o] Error 1 make[4]: *** [all] Error 1 make[3]: *** [mod_java-all] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 mod_java.c: 115 static switch_application_interface_t java_application_interface = { 116 /*.interface_name */ "java", 117 /*.application_function */ java_function, 118 NULL, NULL, NULL, 119 /* flags */ SAF_NONE, 120 /* should we support no media mode here? If so, we need to detect the mode, and either disable t he media functions or indicate media if/when we need */ 121 /*.next */ NULL 122 }; When I look at the method prototype, it looks OK. I do see a difference between the implementation of mod_java and mod_python (which does build successfully) but I thought I would check to see if there is some build configuration issue before pursuing the mod_python implementation issue. Have changes been made to the mod/languages interface that would explain this compile error? Jonathan

simple point to point voip (ATA) connection?
by Zenaan Harkness 11 Nov '07

11 Nov '07

Hi, I have two ATAs - similar to Grandstream 488s, which allows me to convert analogue phones into IP streams. The config server for these devices has options for SIP and NAT/ STUN settings. Can anyone assist me in what I need to do to create a simple point-to-point call, essentially by entering IP addresses manually? The ultimate purpose is so that I can tunnel such connection through ssh tunnel/ forwarded ports. But the first step is to make the (point to point) connection. My machine is Ubuntu. Do I need a SIP server? If so, how can I ensure the RTP stream goes through an ssl forwarded port - ie, how do I ensure the RTP stream goes to a local port, which I then forward using ssh? Thanks in advance Zen

Looking for GXP2000 desk phones
by Trixter aka Bret McDanel 08 Nov '07

08 Nov '07

A couple of non-profit festival companies here in the netherlands are looking for voip phones, they have decided on the gxp2000. I am asking if anyone who is in the community if they are a reseller of these phones to give me a shout if they want to sell about 5 (5 seems to be about right, although it may be more but certainly wont be less than 4). Feel free to contact me directly if you dont want to do it over the list. Contact by email is preferred. I would like to get a price quote, along with estimated delivery delays if you do not have them in stock but could get them. They are likely to want to make the purchase early next week.
