Direct Inward System Access... I know on my old PBX we could do this codes, etc... I know this opens up toll fraud, etc.. but with a code, it's tracked and given out then. Can this happen with CallManager?
The common ways to provide DISA functionality in a CallManager environment are with (1) a custom IOS/TCL scripts, (2) with a 3rd party applications
from partners such as Metreos, or (3) with a scripted CRS application. The CRS solution mentioned below is the most supportable.
The first requirement is that you will need to install a licensed copy of IP/IVR into your cluster. Note that the (free) Extended Services
application is not sufficient, since Extended Services does not include the Work Flow Editor required for creating customizable applications such as DISA. Documentation on IP/IVR can be found on CCO at:
I've setup what I've coined as a "poor mans DISA" for a few clients that insisted on opening their system up for this purpose (something I personally disagree with but the customer is always right - right?). The customers were using any flavor of Unity for voicemail (voice only or unified). Anyway, using Unity 4.0.4 or later ( I prefer 4.0.5 or 4.1.1) you can setup a call handler and use a feature called System Subscriber Transfer to prompt the caller for their voicemail box (number) and password. After entering a valid combination the user can then enter any valid NANP number and be transferred to that number. I usually set the handler to no greeting but you can record a greeting with instructions or anything you want to say to the caller. The customers I have set this up on have had backdoor voicemail numbers so we just map the DISA call handler to a number on the backdoor caller input, usually not advertised by the way, and callers can use the same number to check voicemail and access the DISA function. To secure it further and force an authorization code Ive setup this function on a dedicated voicemail port in a dedicated partition/search space in the lab but never had a customer actually want to enforce this ability. They already were using client matter codes for long distance calls anyway and felt that the voicemail / client matter code combo was enough security.
I'm trying to picture the System Subscriber Transfer and not quite getting. So you have a call handler play a greeting than automatically do a SST... the caller then inputs their xxxx and PW. They then here a ring tone for a complete xxx-xxx-xxxx?
Does CallManager then track the outgoing call from that xxxx?
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
