OBi 110 - white list of callers via PSTN in Italy

(1/3) > >>

antani1971:
Hello Everybody,

just joined this forum since I would like to get a 110 in order to to set it up allowing only callers via PSTN from a white list, both by pattern matching and by exact matching, and routing to PSTN phone (voip functions come second since I have an all-you-can-eat contract with my current PSTN telephony provider)

my question is if this would be feasible and whether this product would work in Italy. I am positive about the feasibility and I have found positive experiences in UK, but none in Italy so far.

Is this product designed to work worldwide?

Thanks

The product is designed to support use worldwide but the ObiTalk web interface I do not believe is.  What that means is you may need to more familiar with the configuration of the Obi than others have, and default values may not be correct for your region of the world.

It definitely can do what you want.  I don't know how big the whitelist can be.  How many people do you imagine being in your Whitelist?  What does the caller ID look like for an incoming number?

antani1971:
Thanks both.

@MikeHObi: good, it may take more time to configure, but it's ok

@giqcass: great. size of the whitelist, difficult to estimate right now, I think however that 2 or 3 patterns + 30 numbers would be ok, but it could grow so it would be good to know if there is any upper limit. the patterns all start with 0 and length is variable (9 or 10 digit), while the numbers could start with 0 or 3 - same length applies.
 

giqcass:
Perhaps someone with more experience with this can chime in.  It appears the easiest way to do this is to put
{(MMyWhiteList):ph}
in the InboundCallRoute for your line port.  MyWhiteList is the label for a User Defined Digit Map. It looks like the max is 511 characters.  You Might be able to increase it by making a second user defined digit map like MyWhiteList2.

{(MMyWhiteList|MMyWhiteList2):ph}

The User Defined Digit Map would have a label of MyWhiteList.  It would have contents similar to
(04195551212|37345551212|xxxx5551212)  | is the expression for or. xxxx = any four digits.  03419xx. would allow any number that starts with 03419 to ring through.  Their are other matching patterns available.

Someone correct me if I have any of this wrong.  I'm not an expert on all of the specifics of digit map/dial plan logic.

Edit:made changes based on

giqcass's reply has a tiny error.  When referring to a map the entry starts with 'M' so if the name of the list in user defined digit maps is MyWhiteList then the string in InBoundCallRoute needs to be MMyWhiteList.  


Thanks for the heads up on the error!
