Hello, im hoping someone will be able to help with this because its just...strange.
We recently migrated a trunk from a PRI to SIP. We had an external company provision the SBC, placed within the UK.
We now have an issue where incoming calls to any station registered in the UK, shows a US formatted number and follows US Rules regarding outbound dialling.
The SIP Trunks are being utilised in the UK.
Where should i start looking at this?
Nothing has changed with the settings file, and its affecting both 96xx and J1xx phones.
