Call between gtalk and sip - no audio
by kriko 23 Dec '08

23 Dec '08

I modified mod_dingaling.c so I can intercept google talk chat messages via socket - nothing fancy. Then I wrote a java app that connects to freeswitch socket and in case of a proper message (trigger) it sends a command to freeswitch, in my case: api originate sofia/default/1001(a)10.99.8.221 &bridge(dingaling/gmail.com/my_mail(a)gmail.com) Dingaling is logged in as another user which I have added as buddy, chat messages go trough, however when a call is started between SIP and Gtalk client, we cannot hear each other at all. Using freeswitch revision: 10866 Here is the log: http://pastebin.com/m1eba2cb8 What can be the problem? First I thought it is because running sip client + gtalk and freeswitch on one host, but then I moved SIP phone and Gtalk to 2 different workstations, using the third only for freeswitch. Also calls from "call" example program from google lib works fine with same setup - something must be problematic with freeswitch, however cannot see what. Thank you! -- kriko

another switch_ivr_set_user() can't find user
by John Wehle 23 Dec '08

23 Dec '08

I'm interested in moving some VoIP phones I'm playing with to a different set of network numbers for various internal reasons. However, I'm not looking for multiple FreeSWITCH domains ... I just want one. Here's what I did: 1) On the FreeSWITCH box created a logical network interface and assigned it a number from the new set of network numbers. 2) Changed rtp-ip and sip-ip in internal.xml to use the number assigned to the logical network interface. 3) Per the FAQ set force-register-domain and force-register-db-domain in internal.xml to the value for domain in vars.xml (i.e. the main local ip v4 address of the FreeSWITCH machine). 4) Changed the VoIP phone to use a number from the new set. When I place a call from the VoIP phone FreeSWITCH complains: [WARNING] switch_ivr.c:1941 switch_ivr_set_user() can't find user [default(a)192.168.14.10] where 192.168.14.10 is the number assigned to the logical interface, however the call goes through / everything seems to work. I'm able to place a call to the VoIP phone from openzap without any complaints. Suggestions / pointers regarding the warning and how to make it happy? -- John ------------------------------------------------------------------------- | Feith Systems | Voice: 1-215-646-8000 | Email: john(a)feith.com | | John Wehle | Fax: 1-215-540-5495 | | -------------------------------------------------------------------------

Need help with "No RTP ports available!"
by Juan Backson 23 Dec '08

23 Dec '08

Hi, I am running some stress testings on freeswitch. When the number of RTP ports reached around 1248 - 1250, freeswitch starts to pop out "No RTP ports available!" error: 2008-12-23 13:14:02 [CRIT] sofia_glue.c:562 sofia_glue_tech_choose_port() No RTP ports available! OS is Centos 5.2 64 bits and freeswitch is compiled with ./configure --64bit options . I also followed the wiki to maximize all my ulimit parameters, but nothing works. Does anyone know why? Any help will be greatly appreciated.

call failed from PLMN to enum number
by Pieter Eduard 23 Dec '08

23 Dec '08

Hi, I have an enum number, if I call the number from any ip extension ( i use default enum.conf that points to e164.arpa) then the call goes well to my ATA that registers to my fs box, but if i try to call the number from PLMN, i get the ring at my ATA and if i pick it up, there's no sound. here's my public.xml config : <extension name="enum"> <condition field="destination_number" expression="^12345678"> <action application="set" data="proxy_media=true"/> <action application="bridge" data="sofia/default/1000%1.2.3.4"/> </condition> </extension> For more detailed debug log, i already submit it on jira : http://jira.freeswitch.org/browse/MODAPP-186 regards, -Pieter-

Performance testing: FS and own App?
by Dennis 23 Dec '08

23 Dec '08

hi, i am quite new to freeswitch and now i finally have fs up and running as i want with my php scripts to handle the calls. now that i want to start the service in the near future, i would like to test the performance of the whole system and the reliability. what are your experiences and ideas, how i could do it the best way? and what do i have to look for? i startet to test with sipp, which seems to be a useful tool, although i am not sure, how to read the results. in the switch.conf i set "max-sessions" to 11000 and "sessions-per-second" to 2000. in the console i entered: sipp -sn uac xx.xx.xx.xx -s 123456 -r 20 -l 1000 -d 4000 -rtp_echo the results are as follow: 20.0(4000 ms)/1.000s 5061 51.18 s 1023 xx.xx.xx.xx:5060(UDP) 20 new calls during 1.001 s period 9 ms scheduler resolution 807 calls (limit 1000) Peak was 807 calls, after 51 s 0 Running, 807 Paused, 0 Woken up 0 out-of-call msg (discarded) 1 open sockets 75989 Total echo RTP pckts 1st stream 481.979 last period RTP rate (kB/s) 0 Total echo RTP pckts 2nd stream 0.000 last period RTP rate (kB/s) Messages Retrans Timeout Unexpected-Msg INVITE ----------> 1023 0 0 100 <---------- 1023 0 0 180 <---------- 0 0 0 183 <---------- 249 0 0 200 <---------- E-RTD1 249 0 0 ACK ----------> 249 0 Pause [ 0ms] 249 0 BYE ----------> 216 0 0 200 <---------- 216 0 0 Counter Name | Periodic value | Cumulative value -------------------------+---------------------------+-------------------------- Elapsed Time | 00:00:00:072 | 00:08:30:106 Call Rate | 0.000 cps | 4.166 cps -------------------------+---------------------------+-------------------------- Incoming call created | 0 | 0 OutGoing call created | 0 | 2125 Total Call created | | 2125 Current Call | 0 | -------------------------+---------------------------+-------------------------- Successful call | 9 | 2125 Failed call | 0 | 0 -------------------------+---------------------------+-------------------------- Response Time 1 | 00:00:00:000 | 00:02:43:140 Call Length | 00:04:04:169 | 00:02:47:149 i do not get any errors. but i think that it is strange, that there are so little calls running at the same time. when i try to call the same number as sipp does, i have to wait a very long time, till the call is beeing answered. why are there so many paused calls waiting for fs to take care of? is this normal or are there some problems, which i have to take care of? i want to add, that i am using socket outbound with a number of php-scripts, which do a lot of call- and dialplan-handling. i am not using any xml. therefore i am sure, that the results are worse, that they would be with normal xml dialplans. thanks for your help and tipps. dannis

SIP Headers and use of "" in the header
by rod 23 Dec '08

23 Dec '08

Dear All, I've been playing with the freeswitch options for one month now, and I've been able to use it with kamailio working as a registrar. What I'd like to do is to add a diversion header using the following action in the dialplan: <action application="export" data="sip_h_Diversion=<123456789(a)10.10.10.254>;reason="unconditional""/> Please note, that I'd like to put the word "unconditional" between quotes, this is to comply with the SIP gateway to which I'm sending trafic. But I've been unable to set an escape character to use theses quotes, cause as you may understand, without escape character FS will consider this instruction instead: <action application="export" data="sip_h_Diversion=<123456789(a)10.10.10.254>;reason=" cause the quote after reason= is considered as a closing quote for data=". Is there a way to achieve this. Thanks. rod

Memory question
by Dennis 23 Dec '08

23 Dec '08

after doing some testing with fs, i can see in the console, when entering "top", that fs uses 9.9% of the memory. when i do some more calls, the used memory will raise - the memory will not beeing released, till i do a restart of fs. is this a normal behavior or do i have some problems? thanks dennis

Extra loud prompts when transcoded from L16@8000 to G.722
by Andy Spitzer 23 Dec '08

23 Dec '08

Woof! I've noticed that the percieved volume of prompts recorded at L16@8000 is much louder (to the point of distortion) when played back via G.722 on Polycom phones, vs when played back via G.711. The same prompts are also slightly louder when played back on SNOM phones via G.722 vs G.711, but not nearly as obnoxiously loud. I'm not sure if FS can do anything about this, it may be a Polycom issue, but is there a way to apply gain (negative in this case!) during the transcoding process so the percieved volume of the prompts is the same no matter which codec is selected? --Woof!

making outbound call with IPv6
by Jason White 22 Dec '08

22 Dec '08

I'm trying to make an outbound call to an IPv6 host using the pre-supplied internal-ipv6 profile. <action application="bridge" data="sofia/internal-ipv6/nnnn(a)ipv6-host.domain"/> I can ping the host with ping6, and it has a DNS AAAA record. (There is no A record as the host is a friend's box behind a NAT). My own box is also behind a NAT, but it has IPv6 connectivity via a tunnel broker. The error in the freeswitch.log file is: [ERR] sofia_reg.c:1344 sofia_reg_handle_sip_r_challenge() No Matching gateway found It's quite possible I could be doing something wrong, or there might be a bug somewhere, or the provided internal-ipv6 profile might need some adjusting... Suggestions welcome.
