One popular feature that was lacking in the early IP04/08 PBX's is support for UK Callerid. This I'm pleased to say is no longer the case.

I recieved an email from Edwin at Atcom last week asking me to update our IP04 appliance using the process below. I also applied the zapata.conf modifications known to work with Atcom AX400p's and I'm pleased to say that testing was successful - an IP04 working with UK CallerID. We will start shipping all future UK IP04/IP08's with these modifications pre-configured. For those on earlier versions of software you'll need to follow the process below.
 

1. Start an SSH session (using Putty for example)
2. Remove “voiptel-asterisk” and “voiptel-gui-pre” (if this entry exists) from the /etc/autoinstall file
3. Run ipkg update
4. Run ipkg remove voiptel-gui to remove the exist voiptel-gui package
5. Run ipkg remove voiptel-asterisk to remove the existing asterisk package
6. Run ipkg install asterisk-spandsp voiptel-gui to install the new package
7. The following entries need adding to the zapata.conf file in the etc/asterisk/ directory to enable UK CallerID:

immediate=yes
usecallerid=yes
cidsignalling=v23
cidstart=polarity
callerid=asreceived
hidecallerid=no

Restart the device and test
