Prepending +1 to DID Inbound Caller ID

[Chadrick]

Hi, new to 3CX here. This has been asked and answered in many other varieties, but reformatting the Inbound Caller ID of a DID is giving some difficulty. For organization reasons, I need to reformat received Caller IDs from a format like 9543543040 to prepend +1, as +19543543040. Without the +1, incoming calls are unidentified.

Due to unrelated requirements, the SIP provider is not a 3CX registered SIP Trunk provider.

I have played around with a few different Replace Patterns, but nothing seems to be sticking. I'm not totally certain if the Inbound parameters are not part of the problem. Both have been attached.

I have already reviewed https://www.3cx.com/docs/cid-reformatting/ and while the examples were helpful, they did not help in troubleshooting this exact scenario.

Thanks in advance for any suggestions.

I use this to strip the +1

+1(.*)

\1

So, I would guess, (.*) on left and +1\1 on right may do what you need.

Thanks, I tried (.*) as the Source Pattern (left) and +1\1 as the Replace Pattern (right), but it's still not working.

I currently have "To :User Part" as the "CalledNum" in Inbound Parameters. Did you need to set something else in order for your Strip to work?

Thanks again!

I tested the scenario and it worked for me with an Approved Provider - so not sure about the remainder of the inbound parameters. I think To: User Part is an outbound parameter that should be in place, not inbound.

Thanks, Craig. I really appreciate you pasting your Inbound Parameters also doing a test on your side. Unfortunately, it's still not working on my side. I might have to try to find another way to work around this.

Ok so what exactly isn't being identified and by what? You say you want to reformat the caller ID of a DID because it's coming in as unidentified. Caller ID is for the caller who is calling you. If you are saying calls to your DIDs are not routing because they aren't matching your DIDs you are probably best changing your DIDs to use *. So something like *9543543040 or even *3040 if only the last 4 are unique.
