Default Avaya+AudioCodes issues after changing external IP


We have a Avaya setup with an AudioCodes Mediant 1000 SBC. For a long time everything worked quite well but today we've changed our ISP provider and so the external IP addresses changed also. I thought that changing only the external IP configuration of the SBC would do the trick but it didn't. Right now we are able to receive incoming calls but no way make outbound calls - just fast beeping sound.
I've launched a syslog server and gathered some logs but they, sadly, are a little bit like black magic to me (someone else was configuring the whole system few years ago). Could anyone suggest what needs to be done or checked in order to fix this issue?

How does it look like:
Internal_phones -LAN-> Avaya G450 -LAN-> AudioCodes -WAN(SIP)-> VoIP operator

What I've done:
1. Changed WAN configuration in DATA->WAN Access->Setting
2. Changed NAT IP Address in VoIP->SIP Definitions->General Parameters

Nothing was changed on Avaya G450.
I can attach logs if needed.
