[cisco-voip] SNR and caller-id - cell phone doesn't showcustomers number but instead the office number

[Dennis Heim]

In the US, Verizon typically will only allow did's assigned to that PRI to be outpulsed. If you have multiple PRIs you can get them to setup a "shared screening table"

AT&T-Legacy BellSouth requires a letter to allow this.
SIP providers don't care..
Most CLECS in the SE US don't care..
Matter of fact on a misconfigured PRI I saw the 3 digit extensions being sent out..

I have heard the  story of someone sending 666 as the caller ID just to mess with someone..

Totally carrier dependent..
However there was a note somewhere about a month or so ago about this all changing, due to some new regulations regarding fraud prevention..
I don't remember the details other than not to forward numbers that don't belong to you in an attempt to mask your true identity..

I have literally setup 100s of PRIs and at least in the US  have only 2 instances that i can remember where a provider has not allowed the client to pass their own CLID if its specifically requested. I actually just did a handful of new full and frac PRIs over the past 2 weeks and there was no push back whatsoever from 2 separate providers? perhaps it is provider specific and i have just been lucky?? I don't know... This is almost a mandatory requirement when clients needs to mask with a tollfree number and if this is changing I can foresee many unhappy clients.

I think it is very difficult to convince a provider to allow just everything to pass from your E1's...it is new for me to know that some providers allows you to set caller ID on your own.

Historically we've just had the provider remove the screening table (aka allow CPE to provide CLID) but if your hitting new legislation then I can see SNR for MOST clients going into the toilet. Is q931 debug showing proper CLID on the outbound leg? if so then and the provider refuses to work with you then I agree with the sales people its totally useless. I've been lucky enough not to have this be a problem yet on a PRI.

Sales people are asking if the original calling party number can show up when using Mobility (SNR).  So call comes into office, office dials out up to 4 locations passing the office's caller id to the cell phone.  Lots of telcos block what caller id can come out of your PRI (usually it's your DIDs or the main BTN), a few will pass anything, in the case of this customer their telco limits what they can pass to main number/DIDs.

So the feedback from the customer is that SNR is useless for sales people as they answer their cell phone only based upon Caller ID and now all calls from customers show the main office phone number in caller id

Is there any feedback? Seems the FCC is enacting new legislation limiting what calling party numbers can be passed out, seems a few telemarkers have been forging their calling party number to get around call blocking equipment.

This didn't work as telco is overwriting by policy.
