Add third party Caller ID to cisco VoIP network

Posted on 2011-10-31
Last Modified: 2012-05-12
Situation: We have a third party managing our voice and internet communications and switch and routing hardware.  Our CEO would like Caller ID but they do not provide this for whatever reason.  Is there any third party or in house solutions that I can implement that might solve this?  All that I have researched so far has come up empty based on our current configuration as follows:

VoIP and internet are provided by a third party through a T1 (this company does not give me any detail of hardware config and no access to the hardware).  They manage all the switching hardware and 2821 integrated service router.  We also use Cisco 7941 phones.  It appears that they do not use this router for VoIP and it is controlled from their hardware on their site.  I have limited knowledge on caller ID and how its implemented but it appears that our service provider would need to get it through whoever they use for their PRI.

Any help is appreciated...Thanks.

    Your CEO wants caller ID identification on his phone? Or his number to be displayed on outside numbers?

    This sounds weird, caller ID is a basic feature implemented years ago.... Not sure why a provider would restrict it.

    Regardless of which case from the above you are dealing with, if your provider strips it out, there is not much you can do.

    We want to view CID on our end.  I'm not sure why they don’t support it either but I walked into this situation so don’t have any background on why.  The service provider is specialized in banking and this is a bank so maybe they have some reason.  They have told us that it might be available next year but that’s there's my dilemma.  I don’t enjoy giving bad news to the CEO especially if I have to try and explain a technically complex reason when he asks why?  lol.

    So as I suspected...If I can’t get it from them I have little choice.  Thanks for your input.

    If you have control over a CallManager server or CallManager Express on a router such as a 2821 or something like that, I could possibly help debugging the call to elaborate a technical yet simple explanation why this is not happening.

    If they control everything including the brains of the telephony system, not even if you were technical would you be able to understand what is happening.

    Maybe your approach can be something like "the problem is this, however, here is another provider that offers such feature..." That way you put the solution in his hands, whether he accepts it or not.

    I did the next best thing, I passed the bad news to my boss and dodged that  I poked around a little more and until our contract is up, we are stuck.  Thanks for your comments.  Keep up the good work.
