Re: [Freeswitch-users] Adding Leading Digits To CALLING Number of Outgoing Call
by Jerry Richards 19 Oct '09

Okay, I figured it out. I added the following line to the default.xml file, just prior to the "bridge" action: <action application="set" data="effective_caller_id_number=425349${caller_id_number}"/> Now, 425349 is prepended to the outgoing call's caller ID.

check to see if freeswitch is alive
by Christian Löschenkohl 19 Oct '09

19 Oct '09

hello we have the problem here that our freeswitch server "freezes" from time to time (no sip traffic is possible any more). has somebody here expirience or any idea how to monitor freeswitch to answer the questions - is the server alive - does he process sip messages (invites, registrations) and so on the monitoring should work via cron local and remote (with esl for example) a simple "fs_cli -x 'version'" wouldn't work - it's too simple, am i right? any ideas would be helpful br -- Ing.

How to enforce freeswitch replying to the source port instead of to the one specified in v/m header parametes (Symmetric NAT)
by Tzury Bar Yochay 19 Oct '09

19 Oct '09

Hi, I am struggling with a cellular operator which removes the rport from the SIP messages sent by the client. During the troubleshooting process I have been playing with the NDLB parameters I found mentioned at the fs-wiki <param name="NDLB-force-rport" value="true"/> <param name="NDLB-received-in-nat-reg-contact" value="true"/> as well as with sip-force-contact at the extension xml config file. <variables> <variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/> </variables> I Want to make freeswitch replying to the source port instead of the port supplied by the client, that is to port 12543 instead of to the 7608 as you can see below some pcap dumps of the case. I am not sure if that would solve thep roblem and am open to other suggestions as well. Thanks in advance, Tzury pcap dumps below: ### REGISTER ### User Datagram Protocol, Src Port: 12543 (12543), Dst Port: sip (5060) REGISTER sip:example.net SIP/2.0 v: SIP/2.0/UDP 212.154.128.222:7608;branch=z9hG4bKPj41fa0abd044c35c75598d561b2f93167 Max-Forwards: 70 f: <sip:1013@example.net>;tag=9194adecbf8e8179530eb589e83631db t: <sip:1013@example.net> i: ebf2e3c254517938f90f33d8fd89326d CSeq: 17355 REGISTER m: <sip:1013@212.154.128.222:7608> Expires: 300 l: 0 ### 401 UNAUTHORIZED ### SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 212.154.128.222:7608;branch=z9hG4bKPj41fa0abd044c35c75598d561b2f93167 From: <sip:1013@example.net>;tag=9194adecbf8e8179530eb589e83631db To: <sip:1013@example.net>;tag=166HraN0B149g Call-ID: ebf2e3c254517938f90f33d8fd89326d CSeq: 17355 REGISTER User-Agent: FreeSWITCH-mod_sofia/1.0.3-exported Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE, REGISTER, INFO, PUBLISH Supported: timer, precondition, path, replaces WWW-Authenticate: Digest realm="example.net", nonce="f2f1370c-bc7c-11de-b000-fbe81e221ab4", algorithm=MD5, qop="auth" Content-Length: 0

Hi, Does Freeswitch support TLS Client-Authenticated handshake. Openssl does, but it has to be enabled in order to send the certificate request to the client. I tested simple TLS hanshaking and it wotks well. Thanks.

sofia gateways and linux multipath routing
by François Delawarde 19 Oct '09

19 Oct '09

Hello all, I'm interested in using mod_sofia with multiple Internet connections (configured as a unique load-balancing route using multipath). One solution would be to define a different profile for each connection, but it would be more practical having a unique external profile that would automatically handle everything (detecting multiple public IPs and selecting the right one for a call, being able to select the router for gateway registration...). Routing table: 192.168.10.0/24 dev eth0 proto kernel scope link src 192.168.10.1 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.2 192.168.2.0/24 dev eth2 proto kernel scope link src 192.168.2.2 default proto static nexthop via 192.168.1.1 dev eth1 weight 1 nexthop via 192.168.2.1 dev eth2 weight 1 Both default routers (192.168.1.1 and 192.168.2.1) would have a distinct public IP. Several questions cross my mind: - Can a unique sofia profile be bound to multiple IPs (not 0.0.0.0)? - How would FS behave with a unique external profile in that situation? * Would FS reply to an incoming call using the same router it came from forcing packet source address? * Would FS stick to a unique router for all flows of an outgoing call (SIP, RTP, UDPTL)? * Can I force a gateway to use a given router (for calls, registration, ...)? * Would the NAT system (using stun or auto-nat) work in that situation, or does it assume only one default router (and a unique public IP) exists per profile? - Knowing the above, would it be necessary to use a different profile for each router/interface, and define the same gateway in each of these? - Tricky question: What if multiple routers are on the same network/interface (192.168.1.1, 192.168.1.2, ...)? Thanks in advance, François.

Re: [Freeswitch-users] NAT problems migrating from Version 1.0.trunk (13168M) to Version 1.0.trunk (15166)
by Chris Fowler 19 Oct '09

19 Oct '09

I've tried all sorts of debug and parameter changes over the weekend, but still can't figure out the correct solution. If I disable timers on the sip profile then all works fine. <param name="enable-timer" value="false"/> But that seems like a hack; not a correct solution. With the build 13168M (which is pre the new NAT functionality) everything worked fine. The SIP trace shows the phones and FreeSWITCH happily exchanging NOTIFY and "200 OK" messages. Audio's working - just calls timeout after 100 seconds with RECOVERY_ON_TIMER_EXPIRE. Is enforcement of this timer new functionality - and really just exposing a problem I've always had before? The config is (50 Polycom Phones -> NAT -> Internet -> Amazon EC2) I would really appreciate some pointers on what to look for; additional trace that might reveal something. Thanks, Chris.

set up sound on windows
by Timur Irmatov 19 Oct '09

19 Oct '09

Hi! We are currently developing small call-center for our company using FreeSWITCH. Our demands are pretty low at the moment, and we have implemented all necessary features, now moving to testing.. We manage FreeSWITCH through mod_erlang_event. FreeSWITCH and mod_erlang_event are great, I want to thank all developers for those two great pieces of technology! We met strange problem with windows clients though. It is not related to FreeSWITCH, but I don't know where to ask. Tried searching google, but found nothing. As soon as we plug headset with microphone into windows machine, we immediately start hearing environment though headset. It seems as sound from microphone is transferred to earbuds, which is pretty annoying. Does anyone have any hints regarding configuration of audio/mics on Windows? -- Timur Irmatov, xmpp:irmatov@jabber.ru
