Dynamic WAN IP
by John Tuxies 08 Aug '20

08 Aug '20

I am doing my first steps with Freewswitch and i have a few questions regarding the config. I have a DSL connection at home with dynamic WAN IP and the router has the No-IP script to resolve a domain eg atux.ddns.net how can i configure it in the Freeswitch, please? Also how do i configure a STUN server, since i would like to register some remote extensions on Freeswitch, for testing. How do i configure a STUN server and if you have a decent STUN server to suggest, please.

Weird behaviour/unavailability of a B gateway
by Igor Potjevlesh 06 Aug '20

06 Aug '20

Hello, I'm facing an issue with Freeswitch. Suddenly, and on an random basis time interval, calls are no more forwarded to the B gateway. I see then that Freeswitch did an attempt to start sending the call to leg B but finally terminate on 503. And a tshark doesn't shows that an INVITE is sent to the B gateway. The result of a "sofia status" on the concerned gateway showing that the gateway is considered as Up. Freeswitch is running on version 1.10.1. B gateway is reach through a DNS URI. Would it be possible that one time failure (such as 1x503 from B gateway and/or a failure in the DNS lookup of the URI) could result in this behaviour?

registration with DID range
by John Tuxies 06 Aug '20

06 Aug '20

for lab purposes i need to emulate ITSP connectivity with multiple DIDs (range of numbers). For example in FS create 4 extensions 1000-1003. Each extension will forward a particular range of numbers: -1000: +441144630000-99 -1001: +441144630100-99 -1002: +441144630200-99 -1003: +441144630300-99 Then different PBXs will get one the numbers 100x and register it as sip trunk eg 1000@FS_LAN_IP. I would like to ask for some help on how to configure it, please.

Issue with SDP - Call hangs up right after SIP 200 OK
by Marc Bernard 05 Aug '20

05 Aug '20

Hello People, Ive been investigating an issue with SDP when sending a call to a Panasonic KX-TGP600 Phone, the call end as soon as the Panasonic send its SIP OK I could not see what is wrong with the SDP and why I get "INVITE: error parsing SDP answer in 200 OK" resulting in "988 Incomplete offer/answer" I also find it weird that there is no output for this error when Sofia debug is not enabled. It took me a while before I thought of trying to enable more debugging. There is also the "not found by name */1.1.217.127:1029" Part which I am not sure is related/relevant in this. -- Here is the console log portion that I thought was relevant: 2020-07-17 15:44:33.495660 [DEBUG] sofia.c:7325 Channel sofia/private/+15145557030(a)2.2.127.218 <mailto:sofia/private/+15145557030@2.2.127.218> entering state [early][180] nua.c:366 nua_handle_magic() nua: nua_handle_magic: entering 2020-07-17 15:44:33.495660 [NOTICE] switch_ivr_originate.c:556 Ring Ready sofia/private/+15145557030(a)2.2.127.218 <mailto:sofia/private/+15145557030@2.2.127.218> !

mod_http_cahce doesn't delete old media files using default-max-age
by Yuriy Nasida 05 Aug '20

05 Aug '20

Hi guys, Do you know why mod_http_cahce doesn't delete old media files? FS only removes internal cache data but downloaded media files still here after default-max-age timeout. I have to reload this module to get audio files removed. Thanks.

Internal profile stops responding
by Stefan Kainz 04 Aug '20

04 Aug '20

Hello, i have come by a very strange problem. The internal sofia-profile just stops responding after a few days on Port 5060. Restarting the profile does not help, but restarting freeswitch itself does. Strangely enough, the external profile ( on the same ip, but different port of course ) keeps working. No Problems there. A few things i have checked while it was happening the last time: - Profile watchdog is disabled - netstat -tlupn shows that freeswitch is still listening on Port 5060 - There is nothing useful in the logs, especially no error/crit message - I can see sip-traffic arriving on Port 5060 with tcpdump, but it is not answered - turning on sofia loglevel all 9 does not show anything - It is not one or two specific ip's that get blocked, but all traffic I also checked the firewall / fail2ban, but no problem there either. After all, a restart of freeswitch solves the problem, with no changes to the firewall. It happens on pretty regular basis ( every one or two days ), but there is no time-pattern in between the occurrences. Im using debian 10, with FreeSWITCH Version 1.10.3-release~64bit (-release 64bit). Has anybody come across something similiar? regards,

Retrieval of Caller-ID
by Chandramouli P 03 Aug '20

03 Aug '20

Hello, Please find my below environment: Operating System: Debian (v. 9.13) FreeSWITCH Version: 1.10.3 (64bit) Softphones that I am using: MicroSIP, 3CX, Grandstream I hosted our server in AWS and was able to make and receive calls successfully. Along with "valet_park_in" and "valet_park_out", also enabled the "CID Lookup" module. I am facing two issues in Valet parking and below is the scenario: User A calls User B. User B transfers User A call to *5900. Now User B is free, and User A is in valet parking at 5901 extension. Here, It is announcing the parked extension i.e. 5901 to User A, instead of User B. It should announce to User B. Right? *How to solve this issue?* Now, User C calls *5901 and is able to speak to User A. In this scenario, User C should be able to see the caller ID of User A. *How to get the caller ID of User A and display and display to User C?* Any help would be appreciated. Thank you. Best Regards, Chandramouli.

Re: [Freeswitch-users] Can a module tap media?

Where can I find guidance about creating a media bug for audio+video? Adapt mod_cv? I'd like the inbound streams to be handled by a scriptable env like python. Or could streams be exposed to mod_python? ---------- Forwarded message ---------- From: Brian West <brian(a)freeswitch.com> To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org> Cc: Bcc: Date: Sun, 26 Jul 2020 13:02:47 -0500 Subject: Re: [Freeswitch-users] Can a module tap media?
