T38 Fax Fallback
by Callum Guy 08 Dec '17

08 Dec '17

Hi All, I'll try and keep this simple. We are experiencing difficulty transmitting fax with a certain UK provider (BT) who have suggested the fix for the fault is that we "*should fall back to using G711 pass through in order to negotiate/ send fax*" The call initially connects with G711 (and the media is proxied). Fax is detected by the originator which issues a RE-INVITE request to use T38. This is rejected by the gateway with a 488 at which point we would expect the call to fall back to G711 however FreeSWITCH is reporting that this is not possible due to a media bug: "*Session is connected to a media bug. Re-Negotiation implicitly disabled.*" My understanding was that a media bug would be required for the initial fax tone detection which subsequently triggers the T38 session start? Could anyone confirm whether we need to be looking into closing off the media bug manually or if there is an alternative route to resolving this issue? We are running FreeSWITCH (Version 1.4.26 64bit). Calls are dispatched with setting "t38_passthru=true". Any help would be very much welcomed.

RTP Timestamps
by Konrad 07 Dec '17

07 Dec '17

I'm running into an issue where Freeswitch is sending out RTP with old/duplicate timestamps. A wireshark trace will show the something like the following randomly throughout a call: Seq=19567, Time=26560Seq=19568, Time=26880 <--Seq=19569, Time=27040Seq=19570, Time=26880 <--Seq=19571, Time=27200Seq=19572, Time=27360 Initially I thought this was related to vmware, but I am getting the same results on bare metal. Server load doesn't seem to matter. Server is a dual xeon with quad cores. Timer_test runs clean. I've tried setting <rewrite-rtp-timestamps> = true, but that didn't help. OS is Debian Jessie with FreeSWITCH (Version 1.6.19 -36-7a77e0b 64bit) Any thoughts? Thanks,Konrad

Problem setting pa_ring_file with global_setvar
by Paul Mateer 07 Dec '17

07 Dec '17

I’ve run into as issue when trying to set the pa_ring_file variable to a tone stream value. If the chosen value contains one or more elements relating to in-memory copies, volume or the number of loops then the global_setvar_function incorrectly parses the value as conditional and fails to set the value. Anyone know of any way around this? Paul Sent from my Windows 10 phone

06 Dec '17

I guess I'm missing something with this setup: Freeswitch-1.6.19 built from source on Win 8.1, com0com 3.0 signed, pair on COM6 and COM7 the and soft modem for fax server is on COM7 I had to set number of modems to 6 in config, otherwise I was just getting no modems available. Mod_spandsp sees the port: 2017-11-29 23:43:52.885349 [DEBUG] mod_spandsp_modem.c:371 Modem COM6 [INIT] - Changing state to INIT 2017-11-29 23:43:52.885349 [INFO] mod_spandsp_modem.c:373 Modem [COM6]->[(null)] Ready but when I bridge to modem/6/123 I get: 2017-11-29 23:44:49.203916 [ERR] mod_spandsp_modem.c:1390 Modem COM6 In Use! 2017-11-29 23:44:49.203916 [ERR] mod_spandsp_modem.c:1398 No Modems Available! 971de557-adb4-4a19-9e7d-ab4f13b954be 2017-11-29 23:44:49.203916 [ERR] mod_spandsp_modem.c:862 Cannot find a modem.

Best practices for recording audio prompts
by Michael Avers 06 Dec '17

06 Dec '17

Hello, Can anyone share some tips about recording good audio prompts? We ideally would like to have them in a variety of sample rates (as they will be used internally as well as when callers dial in from PSTN) to avoid resampling as much as possible. What should it be recorded as originally? Would we then just use sox to resample? Any good apps for Windows? (I haven't used Windows in many years but the person who will be recording would be). Any other considerations to take into account would be greatly appreciated.. it's our first time recording our own set of prompts. Thanks Mike

ACL: auth_calls + apply-inbound-acl/auth-acl
by Anatoli 06 Dec '17

06 Dec '17

Hi all, I'm trying to understand FreeSWITCH's ACL concepts, but I find the documentation not clear with respect to a combined effect of various *acl* params with auth-calls. Could you please provide your comments on the following? The documentation (https://freeswitch.org/confluence/display/FREESWITCH/ACL) says: /auth-calls: Can be set to true/false forcing users to authenticate or no on the profile. Only allow users from a specific cidr to register/make calls.// / First of all, it's not clear what's the default value of the auth-calls param. If it's not explicitly defined, is it true or false? (BTW, same happens with a lot of other params, i.e. no default value specified in the docs, and for some params I couldn't even find the default values in the sources.) Then, if auth-calls is set to true, will it ignore all *acl* params and always force auth? Or will it force auth only for those not specified in the *acl* params (e.g. IPs in apply-inbound-acl won't be forced to auth, all others will be). Similar doubt with the false value: will it always ignore auth or will it ignore auth for the IPs in the *acl* params and still require it for everything else? Then the documentation specifies: /apply-inbound-acl: Allow users to make calls from a particular cidr without authenticating. Phones having IPs within these ACLs will be able to perform calls (apply-inbound-acl) or register (apply-register-acl) without having to provide a password (i.e. without getting a "401 Unauthorized" challenge message).// / So if I understand it correctly, if I want a particular host (e.g. my SIP trunk provider) to make inbound calls without auth, but everyone else to be rejected with Unauthorized, I should specify in the corresponding sip profile: <param name="apply-inbound-acl" value="1.2.3.4/32"/> The documentation adds: /The ACL behavior is modified by auth-calls, accept-blind-reg, and accept-blind-auth./ So what should be the value for auth-calls in this case? How would it modify the behavior of apply-inbound-acl (i.e. apply-inbound-acl + auth-calls=false and apply-inbound-acl + auth-calls=true)? Then, the documentation says: /auth-calls: Users in the directory can have "auth-acl" parameters applied to them so as to restrict users access to a predefined ACL or a CIDR. Note: this will require "auth-calls" to be set to true in your sip (sofia) profile.// / So, if I want to restrict my internal users to be able to register (providing their passwords) only from a specific range and be rejected with Unauthorized for other IPs or if not providing auth, should I configure the profile this way? <param name="auth-calls" value="true"/> <param name="auth-acl" value="1.2.3.0/24"/> My doubt here is: would auth-acl add an additional level of restriction without altering the default behavior of auth-calls (that is to request auth from everyone) or would it somehow relax the default behavior for some cases? Thanks, Anatoli
