The problem with the translation of external calls to CUCM 7.1

[aa.nikanshin]

CUCM 7.1

Colleagues, please help the solution problems:

Improperly transferred calls. Inside calls are translated perfectly. But if are calling from an external number, the transfer of the call incorrect.

After transfer the caller hears one beep, then silence for 20 seconds, then beeps are normal. The called party receives the call correctly.

thanks in advance

Unfortunately, the description is not quite clear to me. Is that an issue with translation pattern or the MOH is not played ( instead beep is played ) for transferred calls ?

A clear call flow & an elaboration would help answering it quickly.
