SIP over TCP with Sipdroid, an Android SIP client
by Carlos Talbot 09 Feb '10

09 Feb '10

Anyone use sipdroid on their Andorid phone? For the most part it works with the exception of when using SIP over TCP. For some reason, after 30 seconds into a call FreeSWITCH sends a bye and drops the call. Why use TCP? The author claims significantly increased standby times using SIP TCP over 3g: http://code.google.com/p/sipdroid/wiki/NewStandbyTechnique According to Brian it might be because the phone is not setting a transport in the contact field and FS is falling back to UDP. This is on r16557. Here's a sip trace along with call graph: http://pastebin.freeswitch.org/12064 regards, Carlos

FS has provisions for keep-alive, see the bottom of the page for ping time value: http://wiki.freeswitch.org/wiki/SIP_Provider_Examples To watch the pf firewall hole timing you can install pftop from FreeBSD ports/sysutils which displays the filter states 'and more'. -kim

UPnP Timeout
by Troy Anderson 09 Feb '10

09 Feb '10

I have been using pfSense (1.2.3) and FS. FS nicely uses UPnP to poke holes in the firewall, but it seems that the holes close after a while. I cannot find any documentation in FS nor in pfSense as to what the timeout is. Is there a setting in FS to do some kind of keep-alive thing with UPnP to keep, e.g. 5060, open? Or is it already doing that and pfSense is the issue? Thanks!

Redirect during Bridge
by Lon Baker 09 Feb '10

09 Feb '10

Hi, I need to bridge calls to a proxy that issues a redirect command. Its an internal proxy that translates internal SIP URIs into outbound URIs. I have one interface on a private network where the proxy is running and another interface on my public network. If I am reading the debug information correctly, the bridge to the proxy is getting the redirect correctly, but since it is on the internal network (profile), the call never transitions to the public network to complete the call. Is it possible to do this? Lon

mod_limit requires media?
by Kristian Kielhofner 08 Feb '10

08 Feb '10

Hello everyone, I was playing with mod_limit earlier tonight and I noticed that it essentially stopped hashing/tracking calls once bypass media was set. Is this by design? Is there some reason mod_limit requires media? Other than that mod_limit looks to be very well implemented (no surprise there) and I'm excited to put it to more use. Thanks! -- Kristian Kielhofner http://www.astlinux.org http://blog.krisk.org http://www.star2star.com http://www.submityoursip.com http://www.voalte.com

mod_nibblebill, loading A-Z rates and CDRs
by Gavin Henry 08 Feb '10

08 Feb '10

Hi all, We're testing FS and mod_nibblebill for a wholesale platform. So far it's working ok via ODBC. I'd like to know how you'd recommend loading A-Z rates that have peak, offpeak and weekend rates. I was thinking about using the conditions for destination to match the time of day: http://wiki.freeswitch.org/wiki/Dialplan_XML#Condition so each rate would be listed a few times in order to match the time of day. For the destinations I was going to do (http://wiki.freeswitch.org/wiki/Mod_nibblebill#Different_Rates_per_Area_Code) <extension name="uk_landline"> <condition field="destination_number" expression="^0([1-3]\d{9})$"> <action application="set" data="nibble_account=${accountcode}"/> <action application="set" data="nibble_rate=rate_tbc"/> <action application="bridge" data="sofia/gateway/sip.myprovider.co.uk/44$1"/> </condition> </extension> I presume I can have (newbie here) multiple conditions for the time of day? My last question is if there is a better way to load the A-Z rates rather than a massive XML file, like from a DB. I'm still new to FS so not sure how to pull in this data. I presume I could just pull it in via mod_xml_curl and do the same with saving the CDRs to a RDBMS using mod_xml_cdr? Is this a best practice going to the RDBMS (I'm part of the OpenLDAP project so always call it RDBMS so as not confuse a user thinking about the OpenLDAP database backend) via mod_xml_curl? I would thought going directly to the RDBMS is better? I suppose it depends on the system architecture. Thanks, Gavin. -- http://www.suretecsystems.com/services/openldap/ http://www.suretectelecom.com

Hi, Running the latest SVN (16453) under Windows, the console "Version" command displays :- "FreeSWITCH Version 1.0.trunk (UNKNOWN)" Should the version number not include a meaningful build version in the brackets ? regards Dave
