Masking Outbound Call ID on Analog Trunks

[wrickk_2]

Is there a way to mask the outbound caller ID on MGCP configured GS FXO trunks?

On your route pattern(s) in CCM under Calling Party Transformations, set the "Calling Line ID Presentation" to Restricted.

Hope this helps.

Hi Brandon, thanks for your reply. That seems to work for PRI's and T1's but not for analog trunks. It seems like the carrier over rides any attempt to transform or block the CID.

POTS lines will always get overwritten by telco with the actaul number, you can not mask them.

HTH,

Thanks Chris, that's what I suspected.

Good info, Chris. Thanks.
