Fixing CID (Caller ID) on incoming calls with 3CX

In a previous post i talked about going all in on VoIP in the house. Its been nearly a year now, and other than some minor issues related to the VoIP Server being turned off accidently, or a screw up on my end, all is going well. But, one thing i did notice was related to incoming calls and caller Id, specifically on my SIP2SIM card. Essentially, the country code was wrong: for example: Incoming calls from the Virgin Media trunk just show as local numbers (for Dublin, for example, it would so 01xxxxxxx). Using the CID reformatting feature in 3CX, i managed to change this.

All calls that come in starting with 0 are “fixed” and changed to +353 without the 0. When the call comes in though the SIP2SIM card, it does no longer show as a call from the UK, but now shows as a call in Ireland, or where it is coming from, so all the contact details show correctly! Happy days!
