[cisco-voip] Caller ID Manipulation

[Norton, Mike]

Alan, I think the CNAM database lookup is only U.S. thing. In Canada and presumably elsewhere, the calling name is set by the caller (if ISDN or SIP, otherwise by their CO switch if analog POTS) and is passed all the way through the PSTN to the callee.

I’ve never understood why the CUCM web interface calls the field “internal caller ID” because there is nothing internal about it. The PSTN in some countries, such as U.S.A., ignores it, but that shouldn’t be a license for Cisco to misname the field, leading to people getting surprised when they discover that the name is not kept internal.

Likewise, there is nothing about Ben’s SIP provider that I would agree is “very lax.” To me, it sounds very perfectly normal, because that is the way the PSTN works for me.

On my PRI gateways, I modify the outgoing names by using an inbound SIP profile on the incoming SIP dial-peer. This allows me to alter the name in SIP From field based on what number is in the From field. So I can put a generic name for certain number ranges, special names for specific numbers, no change for incoming PSTN calls that are forwarded back out to the PSTN, etc. I think you should be able to do the same on a CUBE. Here’s some snippets of it as an example:

request ANY sip-header From modify "^(.+):.*(<sip:\+17808643696@)" "\1: \"SPRT RVR REG AC\" \2"
request ANY sip-header From modify "^(.+):.*(<sip:\+17805682265@)" "\1: \"TP CREEK SCHOOL\" \2"
request ANY sip-header From modify "^(.+):.*(<sip:\+17807662294@)" "\1: \"WMBLY ELEM SCHL\" \2"
request ANY sip-header From modify "^(.+):.*(<sip:\+17805328133@)" "\1: \"PWSD76\" \2"
request ANY sip-header From modify "^(.+):.*(<sip:\+178035752[01][0-9]@)" "\1: \"PWSD76\" \2"
request ANY sip-header From modify "^(.+):.*(<sip:\+1780357522[0-4]@)" "\1: \"PWSD76\" \2"
request ANY sip-header From modify "^(.+):.*(<sip:\+178083130[5-9][0-9]@)" "\1: \"PWSD76\" \2"
request ANY sip-header From modify "^(.+):.*(<sip:\+17808643741@)" "\1: \"PWSD76\" \2"

Note that inbound SIP profiles has to be turned on under “voice service voip” in order to work. But I guess you could probably do it on the outgoing dial-peer to your SIP provider if you wanted. (I have to do it on incoming because my outgoing is PRI.)

Ben,

You can set calling name on the device or trunk level. Most landlines and businesses not using SIP will only receive the calling number, the name is looked up through the cnam database. You can query the cnam database here: https://www.opencnam.com. The cnam database should be updated to reflect your business name, I recommend spot checking your DIDs to see what is displayed in cnam. I have access to some different sip carriers if you want to do some testing, send me a direct email and I can tell you exactly what we are receiving for your calls.

So, I’ve discovered we have a very lax SIP provider who passes through all our ID signaling from our CUCM to the WAN without any modification – which while great for our external CID# mask, means that our internal caller ID names (Such as “HR Conference Room” and “John Smith”) are being published out as our Caller ID names to any residential or other commercial callers (or anyone who has a cell phone with a caller ID app? Haven’t tested that as I don’t have access to one). I can change this myself, but it would require me to get rid of all our labeling and have everyone have generic internal CID, which is not preferable.

I’ve about to be on the verge of telling our SIP provider to change this to force to our company name across the board, but I was wondering if there was any way I could elect to enforce this on our CID myself, either on UCM or on our CUBE routers for all outbound calls. Globally would be fine, but optionally would be great if I could opt-out certain people that do our marketing and sales.
