PROBLEM: Making Concurrent Calls
by Shan Randhawa 01 Aug '13

01 Aug '13

The problem, i m confronting right now, is that When I make 2 calls simultaneously from 4 phones,it acts like a Conference Call means everyone is listening to everyone, For Example if cell A calls cell B,AND cell C calls cell D,then cell C can hear the conversation between A and B. and similarly vice verse is happening. Here is the extension that i m using to make calls, ------------------------------------------- <extension name="local_call"> <condition field="${python(VBTS_DB_Get name|callerid|${destination_number})}" expression="IMSI\d{15}"/> <condition field="${python(VBTS_DB_Get callerid|name|${username})}" expression="\d{7,10}"> <action application="set" data="target=${python(VBTS_DB_Get name|callerid|${destination_number})}"/> <action application="set" data="port=${python(VBTS_DB_Get port|callerid|${destination_number})}"/> <action application="set" data="host=${python(VBTS_DB_Get ipaddr|callerid|${destination_number})}"/> <action application="set" data="effective_caller_id_number=${python(VBTS_DB_Get callerid|name|${username})}"/> <action application="set" data="hangup_after_bridge=true"/><action application="set" data="continue_on_fail=true"/> <action application="bridge" data="sofia/internal/${target}@ ${host}:${port}"/> -------------------------------------------- Does any one has any feedback on this why this is happening. Thanks in Advance

switch_channel_wait_for_state_timeout
by Stephen Wilde 01 Aug '13

the call to: switch_channel_wait_for_state_timeout(channel, CS_REPORTING, 5000); in "switch_ivr_originate.c" is correct? What I mean is that: CS_REPORTING >= CS_HANGUP then the "switch_channel_wait_for_state_timeout" doesn't wait for CS_REPORTING state: I'm wrong? Stephen

WebSocket for proxied outgoing calls
by mayamatakeshi 01 Aug '13

Hello, I have kamailio SIP proxy with WebSocket support in front of FS using plain UDP transport (not using ws-binding). It works fine for incoming calls: http://sipml5.org --> SIP over WebSocket --> kamailio --> SIP over UDP --> FS plays some prompt. Then, the WebSocket app registers with kamailio and when a call arrives to it at FS, FS sends the call to kamailio and the call is sent to the browser. However, when I try to answer the call, the web app refuses the call with this: SIP/2.0 603 Failed to get local SDP. From: "displayname.user3"<sip:user3@test1.com>;tag=6197r4g0Kar9H. To: <sip:user2@127.0.0.1>;tag=okDK7cd5n34HgaEM9dgs. Call-ID: 2d1ab230-7516-1231-969f-5254000fd208. CSeq: 47333138 INVITE. Content-Length: 0. I suppose this is happening because an SDP for a WebRTC call cannot be a plain one that we send on ordinary calls. Is this correct? So is it possible to instruct FS (some parameter when calling originate or bridge) to prepare an SDP for WebRTC? If not, I was thinking if asking FS to not send SDP in the INVITE would work (late negotiation) as it would receive the SDP in the "200 OK" and send its SDP in the ACK. But i could not find a way to force FS to do this either. regards, Takeshi

List registered users
by Jose Suero 01 Aug '13

I've been searching on how to get a list of registered users, all I found was: "sofia status profile external" which says the amount of Registrations, but doesn't list the actual users. How do I do that?? thanks in advance Jose Suero

Just curious, is there any standard for FS API command output?
by Rafal Gwizdala 01 Aug '13

Guys, I'm communicating with FS through an inbound event socket and almost every command has some different standard for output data structure. Some responses are CSV, some (like 'sofia status profile internal reg') use a 'vertical name:value format , i've seen also different formats I don't remember now. What's worse, the event returned after executing a command (SOCKET_DATA api/response) doesn't indicate if the command succeeded or not. Some commands are nice enough to return +OK for success but not all of them. Am I missing something here? Are there more programmer-friendly methods of getting command results from FS? Thanks RG
