Thanks David

This line was operating with caller id withheld from a Cisco, so I am confident that it is possible to block the caller id on the line.

If I've covered all the possibilities from the Asterisk end I will see if we can get the supplier to assist, but I would prefer to get it done in Asterisk.

It is likely being set by your PRI provider.
Contact them to investigate.

All the best...

It seems that it should be fairly simple, but it is defeating me.

https://wiki.asterisk.org/wiki/display/AST/Function_CALLERID says:
"to hide your caller id, use: Set(CALLERID(num-pres)=prohib)"

That doesn't seem to do it.

The calls are originated from AMI and I have tried a blank "CallerId:" line and "CallerId: <>"". Neither of those made any difference.

I have also tried "hidecallerid=yes" in chan_dahdi.conf, but that has also made no difference.

I assume that I am missing something obvious?
