bind_meta_app blocks DTMFs?
by Mariusz Czulada 15 Apr '11

15 Apr '11

Hi All, I'm trying to implement subconference feature, to allow some participants go (or rather "gosub") to a another conference room to discuss something then get back to the main conference. I use FreeSWITCH Version 1.0.head (hacked-20110112T172836Z). Bellow some configure extracts: >From conference.conf.xml: ... <caller-controls> ... <group name="just_exit"> <control action="hangup" digits="#"/> <control action="hangup" digits="1"/> <control action="mute" digits="0"/> </group> ... </caller-controls> ... <profiles> .. <profile name="confX_M"> ... <param name="caller-controls" value="just_exit"/> ... </profile> <profile name="confX_S"> ... <param name="caller-controls" value="just_exit"/> ... </profile> </profiles> ... >From dialplan (own) public/confX.conf.xml: ... <extension name="confX_join"> <condition field="destination_number" expression="^confX_join$"/> <condition field="${confX_num}" expression="^1(\d{4})$"> <action application="bind_meta_app" data="1 a s execute_extension::subX_1"/> <action application="bind_meta_app" data="2 a s execute_extension::subX_2"/> <action application="bind_meta_app" data="3 a s execute_extension::subX_3"/> <action application="conference" data="confX_${cpnfX_num}@confX_M"/> </condition> </extension> ... <extension name="subX_1"> <condition field="destination_number" expression="^subX_1$"> <action application="set" data="pass_rfc2833=true"/> <action application="conference" data="confX_${cpnfX_num}_1@confX_S"/> </condition> </extension> <extension name="subX_2"> <condition field="destination_number" expression="^subX_2$"> <action application="set" data="pass_rfc2833=true"/> <action application="conference" data="confX_${cpnfX_num}_2@confX_S"/> </condition> </extension> <extension name="subX_3"> <condition field="destination_number" expression="^subX_3$"> <action application="set" data="pass_rfc2833=true"/> <action application="conference" data="confX_${cpnfX_num}_3@confX_S"/> </condition> </extension> ... During connection user is first handled by IVR, where he enters conference number (assume: "1234") which is stored in "confX_num" variable. Then call is transfered to "confX_join". Here I assign actions for *1, *2 and *3 DTMF sequences then join main conference ("confX_1234_M"). When some user presses i.e. "*2" then he also enters subconf 2 ("confX_1234_2"). Those users attached to "confX_1234_2" are at the same time still attached also to "confX_1234_M", but found muted and deaf to other participants. Then, leaving subconference they will be back "alive" in master conference, which I tested by kicking them from "confX_1234_2" manually. Now my problem begins. Then user is on "confX_1234_M" dialing "#" forces user to leave conference, as defined in "just-exit" controls. But when user enters also "confX_1234_2" DTMF codes are no longer processed, neither by master conference nor by subconference. I set "pass_rfc2833=true" but it is not helpful. Did I missed to set something [1] in the dialplan or other config files, or [2] actually no DTMF codes can be processed while in "*2" leg? And if [2]==true: would it be possible to develop such DTMF handling? BTW: DTMFs are not processed while in subconference but if user is kicked off from subconf back to main conference, one can use DTMF codes again to (un)mute (0), join sub (*2) or leave (# or 1). TIA for your help or tips. Regards, Mariusz

Detect T.38 reinvite and transcode?
by Bill W. 15 Apr '11

15 Apr '11

Hi there, Is there a way to have FreeSWITCH detect a T.38 reinvite, accept it, and transcode that into ULAW before sending it on to the B-leg? The fax is neither originated nor terminated on the FS gateway. FS would simply transcode T.38 to ULAW. I looked at the mod_spandsp documentation and it wasn't readily apparent. To be clear host_a -> FS -> host_b host_a sends an INVITE host_b responds with 100, 180, 200 then host_a sends another INVITE with SDP for T.38 Can FS ack that RE-INVITE and transcode, so the legs look like this? host_a -> T.38 -> FS -> ULAW -> host_b Thanks! Bill

The Usage of uuid_preprocess && echo cancellation
by vivid333 15 Apr '11

15 Apr '11

Hi: 1. can any one know the usage of uuid_preprocess? 2. according to the FreeSwitch code, this command would add a bug to the uuid session, initialize echo parameters, and in functions switch_core_session_read_frame/switch_core_session_write_frame do echo handle. but the echo still exist. do any one help me ? thanks.. Echo Scenes: Telephone 1000, 1001 registered the FreeSwitch, 1000 call 1001, 1001 answered( two of them are handfree, producing scary sound); Try Solution: Launch the command-line ulility: #> fs_cli #>: show channels uuid1, uuid2 #>:uuid_preprocess uuid1 recho_cancel=true; #>:uuid_preprocess uuid2 recho_cancel=true; but the echo still exist. can any one help me, thanks!

Re: [Freeswitch-users] Relay Proxy-Authentication requests to the caller
by Dave Horton 15 Apr '11

15 Apr '11

I had the same question/issue myself, and would be interested to know if there is a way. For myself, I had to do two things to get this to work: 1. Disable authentication so that FS would not itself generate a challenge. In vars.xml I added this: <X-PRE-PROCESS cmd="set" data="internal_auth_calls=false"/> and in my internal.xml (because calls were coming in on my internal profile): <param name="accept-blind-auth" value="true"/> 2. Then I had to hack mod_sofia to create a new channel variable containing the received Proxy-Authorization on the inbound leg, and also let me set it on the outbound leg. After that it worked, but I would still prefer a solution that didn't require changing mod_sofia, if one exists... >>Hi All! >> >>I would like to know if there is a param we could set in sofia profile to let freeswitch relay Proxy-Authentication requests to the caller instead of absorbing it. >> >>Regards, >>Hamid
