если я все верно понимаю вывод show call history voice id $id  огорчает:

...
OriginalCallingNumber=1201
OriginalCallingOctet=0x41
OriginalCalledNumber=6100
OriginalCalledOctet=0x81
OriginalRedirectCalledNumber=
OriginalRedirectCalledOctet=0xFF
TranslatedCallingNumber=1201
TranslatedCallingOctet=0x41
TranslatedCalledNumber=6100
TranslatedCalledOctet=0x81
TranslatedRedirectCalledNumber=
TranslatedRedirectCalledOctet=0xFF
GwReceivedCalledNumber=6100
GwReceivedCalledOctet3=0x81
GwReceivedCallingNumber=1201
GwReceivedCallingOctet3=0x41
GwReceivedCallingOctet3a=0x80
...

а вот что говорит debug h225 asn1, вы правы я ничего не понял
