Hi, I've done a fair amount of searching, but am so far unable to find a way of getting this right. We have 200 incoming DIDs, in the format 010 020 XXXX. Internally, we are using matching 4 digit extensions, that are the same as the last 4 digits of the incoming DID. Is there a way to automatically map this for all extensions, so that 010 020 3300 goes to extension 3300, etc? Currently, I need to manually configure this for each DID. Secondly, I'd like to automatically map those same extensions to outgoing caller ID, so that if extension 3333 initiates a call, the CID shows as 010 020 3333 instead of the port default. I can accomplish this if I manually configure all the outgoing caller IDs for each extension, but this is quite a mission. Is there a way to automatically map this? Or even, automatically set the outgoing caller ID when importing from active directory? We deal with 100+ interns every 6 months, and reconfiguring their extensions each time will be quite a burden. We keep the active directory up to date, so it would be great if this could be auto mapped? Maybe there is a script or something that is run when extensions are imported, and I could modify this to set the outgoing CID? Thank you.
