Without more information I would say this sounds like a NAT issue. Also FreeSWITCH 1.4 has been deprecated for quite a while…. 1.6.15 is the current release version.

All IP phones are working but only one IP phone is not workint i.e GXP1625 with Freeswitch. I am able to register extension and also incoming call is working but when making outgoing call then only its not working. I tried same IP phone with Asterisk and its working in incoming and outgoing both. I am using this only for extension to extension calls so incoming and outgoing calls only between extensions. Is Grandstream GXP1625 supported with Freeswitch or not? When I am dialing outgoing call then on CLI getting below logs:- [NOTICE] switch_channel.c:1077 New Channel sofia/internal/2005101@Server_IP [ab84501a-345e-445c-8d4a-52d4d6594e21] [DEBUG] switch_core_session.c:1062 Send signal sofia/internal/2005101@Server_IP [BREAK] [DEBUG] switch_core_session.c:1062 Send signal sofia/internal/2005101@Server_IP [BREAK] [DEBUG] switch_core_state_machine.c:472 (sofia/internal/2005101@Server_IP) Running State Change CS_NEW [DEBUG] sofia.c:8957 sofia/internal/2005101@Server_IP receiving invite from XX.XX.XX.XX:65476 version: 1.4.26 64bit [DEBUG] sofia.c:9124 IP XX.XX.XX.XX Rejected by acl "domains".
