Switching profiles upon 3xx Redirection
by Rahul MathuR 05 Jul '17

05 Jul '17

Hello guys, Thanks for a wonderful product ! I'm loving it. I am working on a situation where FS is installed on a centos7 having 2 ip address internal and public. On internal, I receive INVITE and create a b-leg and send to a Redirect server. This server sends 3xx and populates Contact header. When I receive it, I can see that external profile has already been set. And I can't change it to send it to another profile. Is there a way to do that ? My external profile listens on internal ip. I tried different options mentioned in confluence page but to no avail. Am I missing anything or trying to accomplish something impossible ? Thanks in anticipation. Rahul

Freeswitch registration error with GSM gateway

Hi, I have a VOIP-GSM 16 port Dinstar gateway installed. It has its local IP, SIM inserted and receiving signals but somehow it is not getting registered with Freeswitch as external profile.

Limit
by Shaun Stokes 04 Jul '17

04 Jul '17

Hi All, In our environment we restrict the number of current channels (using limit) per extension, however using attended transfer allows extensions to exceed the limit since leg a ends once the transfer completes which resets the limit to 0. I believe the solution is to apply the limit on leg b, however leg b is initiated via a bridge (with-in our outbound LUA script). How can we apply the limit to leg b, or is there a better solution?

mod_rad_auth dial plan condition to match radius result
by Jospeh Waite 04 Jul '17

04 Jul '17

Hi Guys Nearly there with mod_rad_auth, I have it being called in my dial plan and its sending the Radisu auth and working as expected. I now want to put a condition so that in the event of Radius Auth failing the dial plan will end and not allow the call to be made. I have put the following in the dial plan <action application="auth_function" data="in ${DIALED_NUMBER}, in ${USERNAME}, in ${PASSWD}, out AUTH_RESULT"/> <action application="log" data="INFO AUTH_RESULT=${AUTH_RESULT}"/> <action application="log" data="INFO credit_time=${credit_time}"/> <action application="log" data="INFO return_code=${return_code}"/> <condition field="${return_code}" expression="^16$"> <action application="set" data="execute_on_answer=sched_hangup +${credit_time} alloted_timeout" /> <action application="bridge" data="{sip_invite_from_uri=sip:${sip_from_user}@${sip_network_ip}}sofia/internal/${destination_number}@185.35.229.30:5060" /> <action application="hangup" data="${bridge_hangup_cause}"/> </condition> And I check the freeswitch log and see EXECUTE sofia/external/07966677711(a)185.8.92.3 log(INFO AUTH_RESULT=OK) 2017-07-02 17:28:12.885037 [INFO] mod_dptools.c:1724 AUTH_RESULT=OK EXECUTE sofia/external/07966677711(a)185.8.92.3 log(INFO credit_time=7199) 2017-07-02 17:28:12.885037 [INFO] mod_dptools.c:1724 credit_time=7199 EXECUTE sofia/external/07966677711(a)185.8.92.3 log(INFO return_code=16) 2017-07-02 17:28:12.885037 [INFO] mod_dptools.c:1724 return_code=16 But it fails to execute the bit within the condition. Any Ideas of how to make this work? Regards

Making DTMF tone 'silent' to caller
by Mark Melling 03 Jul '17

03 Jul '17

Hi, I have a scenario where a mobile phone makes a 'normal' call (not SIP/VoIP) into a Freeswitch conference (via a SIP trunk). The dialled number includes DTMF tones to be transmitted after the call is dialled. When sent these DTMF tones can be heard by the mobile phone user. What I want to achieve is that these tones are not audible to the mobile caller. In a previous incarnation of this system the mobile phone dialled into a Twilio hosted conference. In the set-up when the DTMF tones were transmitted the mobile phone user could not hear them. Is it the case that Freeswitch is generating the DTMF tones and if so how can I stop this? If not, what are the possible explanations - e.g. perhaps DTMF tones are played in-band in one scenario versus out-of-band in the other? Any suggestions and thoughts most appreciated. Thanks Mark

Hello, anybody knows why destination number starts with 000298C (in several cases)? I think it is encoded plus sign. -- Regards, Arthur
