Problem with XML preprocessor variable
by Vladimir Klejch 19 May '09

19 May '09

Hi I think i found a bug on XML preprocessor in way of working with preprocessor varibles. I have problem with concatenation of preprocessor variables in XML config. Preprocessor is incorectly concatenatin two preprocessor variables, and building wrong config xml. Best to explain on example: in vars.xml: <X-PRE-PROCESS cmd="set" data="bug_test_1=xpreprocessbug1" /> <X-PRE-PROCESS cmd="set" data="bug_test_2=xpreprocessbug2" /> <X-PRE-PROCESS cmd="set" data="bug_test_3=xpreprocessbug3" /> <X-PRE-PROCESS cmd="set" data="bug_test_4=xpreprocessbug4" /> <X-PRE-PROCESS cmd="set" data="bug_test_sum1=$${bug_test_1}$${bug_test_2}$${bug_test_3}$${bug_test_4}" /> <X-PRE-PROCESS cmd="set" data="bug_test_sum2=$${bug_test_1}^$${bug_test_2}^$${bug_test_3}^$${bug_test_4}" /> then in dialplan: <extension name="x_preprocess_bug1" continue="false" > <condition field="destination_number" expression="$${bug_test_sum1}" > <action application="info" /> </condition> </extension> <extension name="x_preprocess_bug2" continue="false" > <condition field="destination_number" expression="$${bug_test_sum2}" > <action application="info" /> </condition> </extension> but in freeswitch.xml.fsxml: <extension name="x_preprocess_bug1" continue="false" > <condition field="destination_number" expression="xpreprocessbug1$%{bug_test_2}xpreprocessbug3$%{bug_test_4}" > <action application="info" /> </condition> </extension> <extension name="x_preprocess_bug2" continue="false" > <condition field="destination_number" expression="xpreprocessbug1^xpreprocessbug2^xpreprocessbug3^xpreprocessbug4" > <action application="info" /> </condition> </extension> The odd variables are wrong translated by preprocessor . The odd variable used as $${var} is translated corect to his content, but the even variable used as $${var} is mangled and in freeswitch.xml.fsxml is to seen %${var} form of prefious $${var}. This problem only ocur, if tvo variables are direcly concatenated w/o any char between them. config : <X-PRE-PROCESS cmd="set" data="bug_test_sum1=$${bug_test_1}$${bug_test_2}$${bug_test_3}$${bug_test_4}" /> is translated to string: "xpreprocessbug1$%{bug_test_2}xpreprocessbug3$%{bug_test_4}" , to see in extension name="x_preprocess_bug1". If there is a char between concatenated variables (in my test a ^ char), everything is OK, to see in extension name="x_preprocess_bug2". It's this known problem or I'm wrong understanding preprocessor usage ?? Thanks Kleo -- kleo+freeswitch(a)netbox.cz

No ringback for iPhone

I am not receiving any ringback when calling in from an iPhone.

Cisco 7905G IP Phone and Freeswitch
by Errol Livingston 19 May '09

19 May '09

I've compiled/configured freeSwitch on Debian Etch - IP 192.168.24.10 on a computer at home behind a NATing firewall. My firewall/router has SIP (5080) and RTP (16834-) ports forwarded to the computer running freeSwitch. My setup is as follows: a) 2 Cisco 7905G IP phones configured with the latest firmware at extensions 1000 & 1004 b) X-Lite softphone at extension 1001. c) X-Lite softphone at extension 2010 at my office. Calls between ALL devices on my LAN (extensions 100x ) work without problems. I can receive calls from extension 2010 to the X_Lite extension (1001) on my LAN. My problem is that audio from external extension 2010 to either Cisco IP phones on my LAN is one-way. Cisco 7905G to X-Lite works but X-Lite to Cisco 7905G does not! The X-Lite phone at extension 2010 is also behind a NATing firewall! Has anyone experienced this issue before?

SIP/2.0 482 Request merged vs 200 OK
by dujinfang 19 May '09

19 May '09

On register, sometimes my voip client got SIP/2.0 482 Request merged sometimes got 200 ok. 482 also means loop detected. my client only has one account logged in only one place, and no proxy, can I take 482 as 200 OK? Thanks. from RFC 3261: "8.2.2.2 Merged Requests If the request has no tag in the To header field, the UAS core MUST check the request against ongoing transactions. If the From tag, Call-ID, and CSeq exactly match those associated with an ongoing transaction, but the request does not match that transaction (based on the matching rules in Section 17.2.3), the UAS core SHOULD generate a 482 (Loop Detected) response and pass it to the server transaction."

User Directory and Per-user (Channel) variables
by Metik 18 May '09

18 May '09

bridge() appears to be ignoring the "absolute_codec_string" channel variable defined in the User Directory even though "info" shows that it is present. Other variables, such as "effective_caller_id_number" seem to behave correctly which leads me to believe that this may be a very minor bug. In order to ease trouble shooting, I have tried to implement it using a configuration that clings rather closely to the sample/default configuration files... // User Directory sample <user id="5551212" mailbox="5551212"> <params> <param name="password" value="5551212"/> <param name="vm-password" value="5551212"/> </params> <variables> <variable name="toll_allow" value="domestic,international,local"/> <variable name="user_context" value="default"/> <variable name="effective_caller_id_name" value="5551212"/> <variable name="effective_caller_id_number" value="5551212"/> <variable name="absolute_codec_string" value="PCMU"/> </variables> </user> // Dialplan broken sample (relies on the channel variable defined in the User Directory) <extension name="domestic.example.com"> <condition field="${toll_allow}" expression="domestic"/> <condition field="destination_number" expression="^(\d{11})$"> <action application="info"/> <action application="bridge" data="sofia/gateway/${default_gateway}/$1"/> </condition> </extension> // Dialplan working sample (explicit use of the channel variable) <extension name="domestic.example.com"> <condition field="${toll_allow}" expression="domestic"/> <condition field="destination_number" expression="^(\d{11})$"> <action application="info"/> <action application="set" data="effective_caller_id_number=${outbound_caller_id_number}"/> <action application="set" data="effective_caller_id_name=${outbound_caller_id_name}"/> <action application="bridge" data="{absolute_codec_string=PCMU}sofia/gateway/${default_gateway}/$1"/> </condition> </extension> // Gateway sample <gateway name="pstn"> <param name="username" value="outbound"/> <param name="password" value="outbound"/> <param name="proxy" value="192.168.1.1"/> <param name="register" value="false"/> <param name="caller-id-in-from" value="true"/> </gateway>

crash-protection and monit
by Andy Ayers 18 May '09

18 May '09

Hi, Is there any reason why the crash-protection parameter in switch.conf.xml defaults to false and are there any downsides to setting it to true? The documentation says it helps with certain types of crashes, can anyone tell me what sort of crashes in particular it helps to prevent as my freeswitch install seems to crash every few days. Also, does anyone have an example of the monit setup for freeswitch to restart it when it fails? Many thanks Andy

silly (?) questions
by Jean-Yves F. Barbier 18 May '09

18 May '09

Hi list, I just discovered FS (practiced a bit * 2 years ago, but too much unstable) and find it cool, NOT CPU greedy and (almost) working ouf of the web. I'd like to know if "star codes" (such as *98) are normalized or not? (and if so, where I could find a list) Also, as I don't use very much my phone and mostly don't pay for it (I live in france and got unlimited free call for 70-80 countries, and my phone is actually plugged in my ADSL box) I'd like to leave access for other people through something like DUNDi (that I don't really know.) BUT not everything is free (i.e.: cellular phones calls cost €0.22 @ connection + €0.22/min); thus I must forbid this kind of calls. Does anybody have realized that, because I need a good template? Thanks JY -- Old mail has arrived.

freeswitch and invites without sdp in initial invite
by Uwe Kastens 18 May '09

18 May '09

Hi there, Freeswitch looks really interesting. I am trying to connect a softswitch wich does some strange things. If a call arrives from pots the softswitch won't send sdp information in the initial invite. Is this something I can change in the sip-profile with freeswitch? BR Uwe
