Firmware
Have you tried to upgrade the firmware of the 7911 phones? This worked for a previous company I worked at.

Yep, there is a change in the network, the internet provider is changed, but i need to say that telephones can send calls, but it can't receive calls any more in that branch.

Have you watched Asterisk (asterisk -vvvvvvvvvvvvr) as calls come in to see what happens? Can the phones call internally, from extension to extension? What is your upstream connection? SIP trunk? If you have changed ISP, your external IP has probably changed too. This might be affecting registration of the inbound trunk.
try
sip show registrars
sip set debug
and monitor incoming calls

You didn't answer any of my questions...
1. Can the phones call internally, from extension to extension?
2. What is your upstream connection? SIP trunk?
