Помогите - не работают клментские SoftPhonы IAX
Обстановка:
Локалка - на ней Asterix от XORCOM (готовый дистрибутив с * 1.05)
в локалке же SIP софтфоны нормально работают (удалось настроить простенькие схемы с приветствием и временем)
а вот IAX софтфоны не наботают ни один
использовались IAXComm IAXPhone DIAX и т.д.
причем звонок с него - проходит (на SIP или наружу) а вот на него нет

попробую привести куски конфигурации и логов

extension.conf--------------

[general]
static=yes
; we don't want asterisk to write the configuration, as it will write
; everything to a single file
writeprotect=yes

[globals]

exten => 601,1,Dial(IAX2/10.0.0.23,20,r)
#exten => 601,1,Macro(stdexten,IAX/601,,601)
#exten => 601,2,Hangup
