[Freeswitch-users] Echo present.

Hello. On my VoIP phone is registered two SIP accounts. One for FS server and one for a VoIP provider. When calling thru FS server I here my echo, while other partie does not hear its echo. When calling thru VoIP's SIP account, I don't here my echo, never other partie hear its echo. So I think that FS server does not remove echo. How to resolve this? -- Mimiko desu.
