I'm having a hard time wrapping my head around a topic that has become a hot button issue. I need to be able to push CID to the PSTN. This wiki page explains what changes to make on call manager(4.x), but it says nothing about gateways:
I have followed the instructions, but outbound calls are still being displayed as the telco designated CID. Is there something on the gateways(1760V, 1821) that I need to be configuring to make this possible? Beyond that, do I have to tell our telco to configure our 2 PRIs in any particular way to allow this as well? Thanks in advance for any imparted wisdom!
get into the GW and run a debug isdn q931 or a debug voip ccapi inout.
look in the setup message what is you're sending in calling party. if it's correct and what you configured in CCM. call telco, they're overriding and you cannot fix that. telco will have to make changes
if it's the telco CID what you see in the debug then the issue is probably misconfiguration
Thanks for the response. I know next to nothing about PRI provisioning, so maybe you can answer this to me. Does the PRI, as it relates to CID, get configured to either allow us to push our own CID or override; or in other words, is a PRI only ever going to be configured one of those two ways?
Jamie in CUCM where do you set the Caller ID? Lets assume that the system is sending the main telephone number for your facility as the Caller ID. You want to send your DID number as the Caller ID. I assume you set this up in CUCM not in the Gateway?
Check the check box if you want the full, external phone number to be used for calling line identification (CLID) on outgoing calls. You may also configure an External Phone Number Mask on all phone devices.
Note The calling party transformation settings that are assigned to the route groups in a route list override any calling party transformation settings that are assigned to a route pattern that is associated with that route list.
