Freepbx ring group does not call a certain number (or connects incorrectly)

Question

freepbx

I use the Ring Group for calls to mobile phones, respectively, there is a group
388
which has an Extension List: 898589750 ** # (I just hid the number with asterisks) I dial
388 and hear beeps, although the subscriber has a melody on it and there is actually no call. Instead, I fill in my mobile number and calmly call, if I manually dial the number - everything is ok, but through a short number - it does not work. in the log it seems the connection goes through and everything is in order

tail -f full | grep 388
