Call Forward Activation on Telco Switch using Keypad Facility IE
Sorry gents for this lengthy post, but I guess my issue needs some clarification.
In my country, ISDN subscribers can activate supplementary services (e.g. CFU, CFB, CFNA) directly on the Telco Network (this is a typical SOHO Feature). The following lines are taken from the Telco's UNI Specification:
The keypad protocol enables the user to manage (i.e. to program, activate, deactivate and interrogate) some supplementary services. The procedures are similar to those used for normal en-bloc call set-up, with the difference that the Keypad facility information element is used instead of the called party number. The public network reacts with cause values and, depending on the Bearer capability, with tones and announcements.
The user can initialize the keypad procedure by sending a SETUP message to the public network containing the following information elements :
- Bearer capability / Information transfer capability: speech, or 3.1 kHz audio, or unrestricted digital information with tones/announcements, or unrestricted digital information
- Channel identification: as for normal call set-up
- Keypad facility / Keypad information: sequence of IA5 characters, dependent on the specific supplementary service.
Sample Service: CFU
Keypad information (IA5 characters): *67<CFU Destination>#
Announcement: service activated, the registered number is ...
I just can't find a way to put the string into a Keypad Facility IE rather than a Called Party Number IE:
Re: Call Forward Activation on Telco Switch using Keypad Facilit
Interesting. These are ISDN things that cisco often is slow in picking up.
Now, TCL/IVR has support for sending facility IE, although I never tried that.
I would be delighted in writing some script that let you interact with the supplementary services, but even for a prototype only, I would need access to a router for testing (TCL/IVR is a lot of trial and error), and some help in defining what the script does and how.
