asterisk users - Feb 2005 - Terminating IAX calls in E1 PRI interface - what do I need to be able to send arbitrary caller id to called party ?

Hi,

I'd like to terminate IAX call on PRI interface. What conditions should be
met to be able to send arbitrary caller numbers to called party, so he can
call back to supplied ISDN number (that is different for every IAX user) -
not through PRI interface, but plain ISDN call  !!

Thanks in advance,

regards,

Rob.

That one sentence is about as mumble-jumbled as one can get. Try rewriting
it again so someone can actually understand what you're trying to do.

Can't actually tell if this response pertains, but some PRI and ISDN
providers allow you to pass a different callerid "to them" for each 
call, while others do not. So regardless of how you might program *,
part of your answer would seem to be dependent on your provider.

Rob,

 From a technical point of view, this is no problem. Asterisk can set 
any callerid you like, and the PRI can transport it.

The issue is with the provider of the PRI. They may or may not accept 
arbitrary callerids on outbound calls. For example, in the UK many 
providers will only accept callerids that are assigned to the trunk on 
their end. You should check with your provider.

Usually this is available by special arrangement. See ETS 300 092-1 
paragraph 9.4 which describes how this works in EuroISDN-land. Note that 
it up to the provider to allow this special arrangement.
