The DV4mini is not able to do D-STAR CCS7 Callsign Routing.... Since the DV4mini folks invented it, I was surprised to find that it wasn't including on their DV4mini. Below is what Uli Altvater AG0X sent me via email this afternoon.
Hi Dan,
I just talked to Torsten.
Right now this feature is not activated, as every stick would need a CCS7 for a repeater, which is really a 6 digit number.
We have so many DV4minis deployed that we would have run out of repeater IDs if we would have assigned a separate ID to every stick. Right now they share a common one.
He plans to get the functionality back into the system but we would have to use a different scheme to overcome this addressability problem.
Sorry that I do not have better news at this point.

CCS, which morphed from a 4-digit id to CCS7, was invented by Torsten DG1HT and Hans DL5DI. They published a CCS Developer's Manual. G4KLX added the function to his ircDDBGateway. Most CCS practioners use the G4KLX implementation. It takes the original ICOM Callsign Routing idea of routing to the gateway where a callsign was last heard, but expands on it by creating a temporary virtual DCS reflector (hence,ircDDBGatewayConfig has a combined DCS and CCS tab where you can enable either or both). Caller and Callee are silently linked to this virtual reflector, so the callee does not need to hit the Callsign Capture button in order to reply to the caller. Callee can just pick up the mike and hit PTT.
This is why I call CCS CR the "Callsign Routing ICOM should have designed, but didn't" In other words, for many users like me, it is better than ICOM CR. The G4KLX implementation is especially nice because callers can listen before they transmit, and linked users will hear them, avoiding the ICOM CR "hear only one side of a QSO" issue.
Torsten is a leader of the DV4 Team (DVRPTR, DV4mini, DV4Home etc.), so the original DV4mini software supported CCS (4-digit) Callsign Routing. But when the 4-digit address space was running out and they decided to move not only to a longer id, but to adopt the DMR id, support in DV4mini.exe for CCS Callsign Routing was removed. Dan's post with comments from Uli and Torsten explains how even the 7-digit address space could get over run if DMR/CCS7 ids were assigned to every gateway, every Hotspot, every Access Point and every DV4mini.
My contention is this is unnecessary. Currently there is no need to acquire a DMR/CCS7 id for a homebrew gateway and the like. Most CCS7 Callsign Routing is done not to gateways (they are, after all, pretty fixed, IP address-wise). No, most of us want this functionality to locate and connect to a *user's* callsign or CCS7 id. Last heard databases can save where that callsign or CCS7id was last heard by remembering the last heard gateway's IP address.
As a DV4mini user, I would be very happy if DV4mini software would support CCS7 Callsign Routing to user (and only user) CCS7 ids. This change would not have any significant impact on how fast the DMR/CCS7 id number space is used up.
I understand much of current development is focused on MultiMode, but this wonderful CCS7 CR feature that us ircDDBGateway users have available would be useful for DV4mini users also. I hope the DV4 developers are able to find the time to add that function back. Just exclude support for gateways and devices and focus only on users and their DMR/CCS7 ids. Internally, they can keep track of the gateways' IP addresses and not require gateways to have a CCS7 id.

I got an email this morning from Uli of Wireless Holdings that the DV4mini developers do plan to restore CCS functions to DV4mini.exe for routing to users but not devices or gateways. No timeframe, but I consider that good news.

Am I to understand that in order to use ccs7 routing one must have a repeater ID for their Hotspot? I ask because I too am having issues using ccs7.
