one-way voice conversation

We are using HDV card on 3662 to connect to a channel bank and then telco in Iran. the problem now is we can hear Iran side very well buy they can not hear us. however, another company is using a 5300 to connect to the same channel bank and their calls are going well. we have tried verifying input gain and output attenuation, but it didn't help. On our FXO ports on the same router, the calls are good.
