Помогите найти IOS для 2611

Нужен зараза такая, именно этот: c2600-ix-mz.122-2.T4.bin

Нигде нету :(
Может где-то косячу, но трабла такая:

Сейчас залит - c2600-is-mz.120-7.T2.bin

Модуль и FXS виден.

А в мурзилке (http://www.cisco.com/en/US/products/hw/modules/ps2617/products_tech_note09186...) написанно:

Что для 2600 - подходят
11.3(2)XA, 11.3(3)T, 12.0(1)T, 12.0(1), 12.0(3)T, 12.1(1)T, 12.1(1),
12.1(5)YB, 12.1(5)YD, 12.2(1), 12.2(2)T, 12.2(2)XT, 12.2(11)YT, 12.3(1).

Но столкнулся на 12.0 с траблой:
CSCdt20095

Symptoms When a call is placed to a network access server (NAS) that is running T1 channel-associated signaling (CAS) Feature Group B (FGB), the following message is displayed several times:

CDAPI: cdapi_create_raw_msg(): FOR_RAW_MSGS queue is empty.

The Call Distributor Application Programming Interface (CDAPI) memory buffer pool is empty, and the call does not go through.

Conditions This symptom is observed on releases earlier than Cisco IOS Release 12.2.

Workaround There is no workaround.

Но, IOS можно не любой, т.к. мозгов нету в наличии
