[Freeswitch-users] Not able to register single extension from any client

Dear Team, I configured FreeSWITCH on a linux server. Initially, I configured extension 6219 on FreeSWITCH and its working fine. but from last few days, i am not able to register 6219 extension from any client. i tried with xlite , zoiper but its not working. i changed client machine too. All credential for 6219 is correct but still its not working. -- Regards, Shisheer T
