What does SIP headers look like from the two? -------- Original message -------- From: Jose David Jurado Alonso <josedavid@zennio.com> Date: 7/31/17 2:36 AM (GMT-05:00) To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Subject: Re: [Freeswitch-users] FS AWS does not call between mobile phones connected to the same WiFi Hi Giovanni, I have tried with the change you mention, changing the domain by the public IP, but it still does not work. Both devices are connected to the same WiFi, on a TP-Link Archer C1200 router, and in the ALG section I do not see the SIP option. By connecting one of the devices to this router and the other to another network, the call is successful. The problem is when the two are connected to the same network (I have tested with several different networks). It's as if FS does not find the destination number and stays waiting. Both devices are correctly registered and can be called or called by any device as long as it is not on the same network. 2017-07-28 18:05 GMT+02:00 Giovanni Maruzzelli <gmaruzz@gmail.com>: On 28 July 2017 at 20:21, Jose David Jurado Alonso <josedavid@zennio.com> wrote: My current configuration is the next: vars.xml:   <X-PRE-PROCESS cmd="set" data="bind_server_ip=auto"/>   <X-PRE-PROCESS cmd="set" data="external_rtp_ip=host:mydomain.us"/>   <X-PRE-PROCESS cmd="set" data="external_sip_ip=host:mydomain.us"/> try making it: <X-PRE-PROCESS cmd="set" data="bind_server_ip=auto"/> <X-PRE-PROCESS cmd="set" data="external_rtp_ip=135.44.55.123"/> <X-PRE-PROCESS cmd="set" data="external_sip_ip=135.44.55.123"/> Stop and start FreeSeWITCH and see if it helps Also, maybe something is blocked by some ALG in the clients' router? Try to connect via TLS...
