I already have read a lot of descussions about this problen in forum, but I've not find the decision.
I have CUCM 9.1.2 and a lot of MGCP gateways with SRST and FXO ports, in SRST mode I can make outbound calls just fine. But when I try to make inbound call from PSTN on my FXO, I hear 'busy tone'. I use c2900-universalk9-mz.SPA.153-3.M.bin IOS on my routers.

I have the same problem like the person in this topic https://supportforums.cisco.com/discussion/11884511/mgcp-srst-fxo-inbound-call-silence
Could you share your dial-peers that are configured on the gateway? Do you have an incoming pots dial-peer with direct-inward-dial configured on it? Also, do you have 1640XX configured on a phone or do you need translation patterns to complete the PLAR calls?

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
