Need to set up an extension (off my IVR) that takes the input of a dialed string then takes that string and sends it to an external sip server.
For example, caller will call in to my Asterisk IVR and after a prompt enter “8337#”. The call is then transferred to 8337@some_other_sip_address.com
I have tens of thousands of extensions so inputting each one would be prohibitive in the tradtional sense. I would be most grateful for your help.
