TCP vs UDP SIP
by Spencer Thomason 09 May '13

09 May '13

Hello all, In our deployments, Freeswitch is on a public IP with most user endpoints behind NAT. As the demand for BLFs has grown I've been forced to go to TCP due the NOTIFYs exceeding MTU. I've been reluctant to use TCP for SIP due to the increased overhead. Currently I force a registration expiry of 600 seconds and ping all NATed endpoints. I'm exploring the idea of switching all endpoints to TCP where available, ditching the options pings and dropping the registration expiration to 300 secs which should exceed the TCP connection timeout of almost every router I've seen. I was currious if anyone had an experience or could point out any caveats I might run into. Thanks in advance, Spencer

mod_python problems

HI, I am having problems building mod_python. Even though my system python is built with threading support I continue to get the following configure error. Any ideas on what the issue could be?

External Softphone vs. Internal Question
by Jeff Bernhardt 09 May '13

09 May '13

Hi. I have the following basic setup questions: When using a softphone (Bria on iPhone) from external (on a different external ip address), I could register but no audio would be passed either way for any calls. I saw that I should set ext-rtp-ip in the internal sip profile to my external ip address (it was on auto-nat, which apparently wasn't working) in this wiki http://wiki.freeswitch.org/wiki/NAT_Traversal That didn't work, so I also set my ext-sip-ip to my public ip. After that, I could pass audio. However, if I register the phone internally instead and call for instance the IVR test line, the call drops after 30 seconds. So it's either no audio when registered externally or 30 second calls when registered internally. I found this wiki: http://wiki.freeswitch.org/wiki/General_NAT_example_scenarios I fall into either scenario 2 or 3, and for both, it says to create a dedicated profile for external registrations and put them on port 5090, which works. However, is there no other way to solve this problem that doesn't require the use of an additional profile on port 5090 but also doesn't cut off internally registered calls after 30 seconds? On Asterisk, there's no need to open a second port to register external phones. What's different about Freeswitch? Also, I don't know what role these play, but I also get these errors: [WARNING] switch_core_media.c:1282 Asynchronous PTIME not supported, changing our end from 0 to 20 at seemingly random times ...and.... [INFO] switch_nat.c:590 NAT port mapping disabled when I make a call from internally or externally registered softphone to external number. Thank you.

More than likely those files are meant for voicemail. If you do need to use voicemail then you'll need that file so the prompt actually plays.

server crash with latest git 1.2.stable from today (ab7ae9f) mod_rtmp
by bellesoft 08 May '13

08 May '13

Hi, I updated a server to the latest 1.2.stable (ab7ae9f) from earlier today. mod_rtmp seems to be the culprit, each time I disconnect from a flex client, I can reliable crash the server. I am also doing uuid_kill on the channel. I'll get a coredump, and file a JIRA. But wanted to know if anybody else is having the issue. Backtrace here: http://pastebin.freeswitch.org/20887 I also see that there has been a few more commits from the team after, wondering they address this crash? -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/server-crash-with-latest-git-… Sent from the freeswitch-users mailing list archive at Nabble.com.

Hello, Is there any way to present an artificial ring or two to the caller while receiving and processing the DNIS and ANI on an inbound TDM call? There is nearly a 5 second delay during that phase of the call. Thank you, Brian C. Edgar, Jr.

Correlate SendMsg reply with request in async mode
by mbo 08 May '13

08 May '13

I'm referring to a two years old bug report http://jira.freeswitch.org/browse/FS-1309. Is it in the meantime somehow possible to map reply to SendMsg in asyc mode? I'm wondering why this ticket has been closed as "Won't fix", in my opinion is an essential feature to handle events properly. If not, I want to implement the work around described in the ticket, to set a channel variable in a round trip before executing the real command. Do I need to wait for the ChannelExecuteComplete event for the Set command, or can I send my "real" command right away after the Set command? Thanks Markus

How to post dynamic variables
by Rajat toshniwal 08 May '13

08 May '13

Hi I am new to freeswitch and i am trying to integrate one php application with freeswitch. Purpose is freeswitch will send the user dialed (dtmf numbers) as input to this php application and in return it will send the response back. Dialplan which I have written for this is <extension name="inte"> <condition field="destination_number" expression="^9199$"> <action application="read" data="0 9 $${base_dir}/sounds/en/us/callie/conference/8000/input-string.wav res 60000 #"/> <action application="sleep" data="2000"/> <action application="export" data="new=${res}"/> <action application="sleep" data="2000"/> <action application="say" data="en name_spelled iterated ${new}"/> <action application="curl" data="http://192.168.10.27/index.php post id=${new}" inline="true"/> <action application="sleep" data="2000"/> <action application="speak" data="flite|slt|${curl_response_data}"/> <action application="info"/> <action application="speak" data="flite|slt|Thanks for your query"/> <action application="lua" data="helloworld.lua ${curl_response_data}"/> </condition> </extension> Now http://192.168.10.27/index.php this is a url on which i am sending my requests. Problem here is curl is not taking variable in the post. If instead of ${new}, i put some random static value like 256, then it is working perfectly fine but I want my users to input the values. Kindly suugest some way via which I can post variables in curl url ------------------------------------------------------------------------ ---------------------------------------------------------------------------------- Disclaimer: The information contained in this communication is confidential, private, proprietary, or otherwise privileged and is intended only for the use of the addressee.

Contact header, when using sofia gateways
by jay binks 08 May '13

08 May '13

Im hitting an inter-op issue with a specific carrier ( running a Nortel CS2000 ) When I Send a call to this carrier using "Scenario A" everything works fine.. If I send them a call with "Scenario B" the call is rejected with a "502 bad gateway". the carrier has said that the contact header in "Scenario B" is "Too Long". Im not sure its the length specifically... but I wonder if the transport or gw variables are causing their switch to do something odd.. problem is, I cant seem to strip these with any combination of contact variables from the wiki or even after trawling /mod/endpoints/mod_sofia/* . it seems that gateway->register_contact is used for invites also. and the flow of parse_gateways in sofia.c suggests that there is no code flow that would avoid appending the gw= data. can someone confirm if there is a way avoid adding this extra data on calls out a gateway, or if im going to have to raise a request with the dev guys. *Scenario A )* I make an outbound call with this syntax : <action application="bridge" data="sofia/upstream/${bridge_dest}(a)xx.xx.xx.xx "/> I See a SIP Contact of : <sip:mod_sofia@xx.xx.xx.xx:5060> *Scenario B )* I try and use gateways ( for the added functionality of monitoring the far ends reachability ) with this bridge string : <action application="bridge" data="sofia/gateway/upstream_xx.xx.xx.xx/${bridge_dest}" /> I See a SIP Contact of : <sip:blah@xx.xx.xx.xx:5060;transport=udp;gw=upstream_xx.xx.xx.xx> -- Sincerely Jay Binks
