Hi, We need to set up calls in FS where a mono signal coming into Freeswitch is split into a stereo signal. What is the easiest way to accomplish this? Thanks Sent from my iPhone

Setting loglevel beyond 7 ?
by Sharath Kumar 05 Jun '15

All, I noticed some of the logs in the code are using SWITCH_LOG_DEBUG1 =101 - SWITCH_LOG_DEBUG10 = 110. Is there a way to enable these logs from the fs_cli ? I can recompile the ones I want with a lower value but just wanted to avoid that. Thanks Sharath

Re - British Telecom (BT) SIP test list before allowing a server on their IP Telephony network
by Andrew Keil 02 Jun '15

To FreeSWITCH users, Re - British Telecom (BT) SIP test list before allowing a server on their IP Telephony network. I wondered if someone can take a quick look at this test case spreadsheet from BT in the UK to see if a standard FreeSWITCH installation (current production release) will cover off all these test cases. I assume the answer is yes! However I thought that I would ask in advance. Kind Regards, Andrew Keil

DTLS ICE and WebRTC using Freeswitch 1.6
by Jon Lederman 01 Jun '15

01 Jun '15

Hi, We are having trouble getting WebRTC working with 1.6. I have tracked the problem down to the do_dtls function in switch_rtp.c (shown partially below). Two things we have noticed: 1) It appears that ice.ready and ice.ready are always 0. 2) DTLS negotiation never completes the handshake. Does ice have to be operative in order for dtls negotiation to proceed or the other way around? What should I look for, which may prevent the ice setup and/or dtls handshake. We are running on google cloud. Are there networking/NAT issues running on cloud servers that might interfere with either ICE or DTLS? Thanks in advance. -Jon static int do_dtls(switch_rtp_t *rtp_session, switch_dtls_t *dtls) { int r = 0, ret = 0, len; switch_size_t bytes; unsigned char buf[4096] = ""; int ready = rtp_session->ice.ice_user ? (rtp_session->ice.rready && rtp_session->ice.ready) : 1; if (!dtls->bytes && !ready) { //switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(rtp_session->session), SWITCH_LOG_ALERT, "Ice not ready"); return 0; } …

Need help with lua called from dial plan - How to delimit arguments?
by Jim Lynch 01 Jun '15

01 Jun '15

I have a line in my dialplan that looks like this: <action application="lua" data="cid.lua ${caller_id_name} ${caller_id_number}" /> However when the program is executed and the caller_id_name has a space in it, the number gets lost. I can't figure out a way to add delimiters that get passed to the shell. None of these work: <action application="lua" data="cid.lua \"${caller_id_name}\" \"${caller_id_number}\"" /> or <action application="lua" data="cid.lua ''${caller_id_name}'' ''${caller_id_number}''" /> or <action application="lua" data="cid.lua \"\"${caller_id_name}\"\" \"\"${caller_id_number}\"\"" /> None of those work. The quotes are all stripped off when running this test lua file: tmp_file = "/tmp/cidtest.txt"; local file = assert(io.open(tmp_file, "a")); local m_name=argv[1]; local m_number=argv[2]; file:write("j cid is ",m_name," number is ",m_number,"\n"); Any suggestions? Thanks, Jim.

LuaSQL doesn't work in Freeswitch
by Doug Vought 31 May '15

31 May '15

<https://freeswitch.org/confluence/display/FREESWITCH/Lua+with+Database> On this confluence page, it indicates that one can use LuaSQL to connect to a database. FreeSWITCH Version 1.4.18-1~64bit (-1 64bit) Lua 5.2.1 Linux freeswitch 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 Utilizing the LuaSQL-sqlite3 database connector, I will attempt to INSERT, but the value never gets inserted. The reason I think it is freeswitch is because utilizing the same code (without the freeswitch hooks), the INSERT works just fine. Here's what I'm doing: api = freeswitch.API() > require"luasql.sqlite3" > env = luasql.sqlite3() > conn = env:connect("db.db") > session:answer() > query = [[INSERT INTO TEST_TABLE VALUES("0000000000")]] > session:consoleLog("info", query .. "\n") > conn:execute(query) > conn:commit() > conn:close() > env:close() > session:hangup() > The Lua interpreter is not throwing me any errors and the dialplan ends, so I assume it's working. I go into the database to see and nothing has been inserted. Also note: I did try to make sure I was taking locking into account by giving env:connect() the appropriate millisecond value, but this did not change anything. If I do this same thing, but without Freeswitch involved and ran by the Lua interpreter: require"luasql.sqlite3" > env = luasql.sqlite3() > conn = env:connect("db.db") query = [[INSERT INTO TEST_TABLE VALUES("0000000000")]] > conn:execute(query) > conn:commit() > conn:close() > env:close() > The values are inserted. ---- I am putting this here because I am assuming this is a failure on my part and I don't want to muck up Jira if that's the case. BUT, it would be nice to see the LuaSQL recommendation removed if doesn't work as expected with Freeswitch. Can anyone try this and see if they are having the same problem? Maybe we can save a few people some time by getting that info off of the confluence page if it's found not to work with multiple people :). Thanks, Doug
