[Freeswitch-users] iLBC question

As I wrote, we tested several clients.
One example of call from Zoiper (alex_gusak) to Zoiper (edward).
( Zoiper <-> SER <-> FreeSWITCH <-> SER <-> Zoiper )
The first client sends iLBC rtpmap: 98, mode = 30, FreeSWITCH sends to
second client iLBC rtpmap: 102, mode30.
Both the client did not hear one another.
The same situation if the call directly through FS without using SER
(Zoiper <-> FreeSWITCH <-> Zoiper)
call sip_trace:
