Hi...thanks for taking the time to look at this....
I have an issue where i have configured service DSAPP globally to enable hookflash for SIP to enable supplementary services for analouge phones connected off the routers FXS ports. I am running IOS 15.0 M2.
I can sucesffuly invoke hookflash and do call waiting, call hold and 3 party conference, but I cannot get call transfer to work.
I founf this article which states that I need to use a TCL script to invoke call transfer ( bline consult etc)
My qestions are:
1: Do transfers ( blind/Consult etc) need to be invoked via TCL script when pressing hookflash
2: Would the TCL script then need to perfom the following too ?
2a: Call Hold
2b: Call Waiting
2c: 3 party Conference
3: Would impelenting under POTS/VoIUP dial-peers service TCL-APPLICATION-NAME change behavior of service DSAPP under dial-peer configuration(even if Service DSAPP is enabled Globally to invoke Hookflash Support) ?
4: Has anyone else done this/Do they have a sample TCL script that I could possible get/use/modify as a starting point ?
Basis for these questions comes from the following Cisco document
SIP Call Transfer and Call Forwarding Supplementary Services http://www.cisco.com/en/US/docs/ios/12_2/12_2y/12_2yt11/feature/guide/ftsipcal.html#wp1027173
in which it states the following:
The SIP Call Transfer and Call Forwarding Supplementary Services feature is supported only through TCL IVR 2.0 and VoiceXML applications.
And:
Before implementing blind transfer and call forwarding, a custom TCL IVR 2.0 script must be written that implements call transfer and call forwarding functionality.
Kind regards
Paul
