Hi All,
Not entirely a VoIP question but figure it fits in here anyway...
Having some trouble modifying CLI on ISDN lines. I know for sure our PABX's used to do it no problem, and still do. Just have one site in particular where we can't send out specific CLI's per extension. This is important as they have many many DDI's and want them to be the outgoing CLI when making a call out.
Is anyone aware of any recent changes that stops this happening? Telecom have asked us to send them information on what the phone system is actually sending out.. we have no idea how we can capture this information... wouldn't be a problem on SIP but just don't know how to go about it for ISDN.
Next part of the question is we have the same issue when running through VoIP. It seems when we use the 'old' 2Talk platform (202.176.....) there is no issue using whatever outgoing CLI we want but on the new (27.111.....) we can only send numbers that actually belong to the account. This is annoying... But I think it will be fairly set in stone and probably something to do with nuisance callers.
Any help much appreciated.
