При попытке отправить факсы с DG-102SH или с DG-104SH связь через некоторой время разрывается и всё.

Прошивки:
на DG-102SH - dg102SH_firmware_b43
на DG-104SH - 104nmm._NEWEST!!!tfp и 104P_B13.tfp

Настройки:
set h323 t38 on
set h323 t38_req_initiater callee
set coding 6 fax_tcf_method 2
set coding 6 fax_t30_features ecmon
set coding 6 vad off

еще пробовал и доп. настройки:
h323 h245_term_type = 60
h323 endpoint_reg_type = terminal
h323 fast_start = off

что на том, что на другом шлюзе .

В итоге выдает в терминале:
Get_Tcid_By_LocNum() fail of hsmup_send_rtcp_sr

Как можно поправить?

Вот еще конфигурация при команде show coding:
