How to block SIP caller ID to PSTN?

Hi all,

We have a small office running CME. The customer doesn't want caller ID being presented for calls out the PSTN. For the SCCP phones, we have simply added the "caller-id block" command under the DN and this works. We have a few iPhone users using SIP clients, but can't seem to block the outgoing CLID on this. I did some searching and have tried the clid strip pi-restrict all command, but the calls still present to the PSTN as the main switchboard number. Config below:

voice service voip

clid strip pi-restrict all

allow-connections sip to h323

allow-connections sip to sip

no supplementary-service sip moved-temporarily

no supplementary-service sip refer

fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711ulaw

h323

  call service stop

sip

  registrar server expires max 3600 min 120

  no update-callerid

Is there any way to achieve this?

Thanks

Are you looking for blocking calling number permanently and for every call ?

Then

dial-peer voice xxx pots

caller-id restrict

for all DPs.
