Hi,
I'm looking at a DTMF solution for provisioning of a subscribers settings.
For example, when the subscriber wants to update settings in a proxy for
DND, the subscriber should dial:
*21# to enable
*21* to disable
which the proxy should intercept (not forward the call somewhere) and update
this subscribers settings
My problem is that I'm not sure if a SIP stack would support sending a #
character in a sip URI (or telURI). * is a valid character as far as I can
understand from the RFCs, but the # must be escaped. Is is at all possible
to have # in the sip uri? Do anyone know if any examples (maybe in some call
flows)? The stack I'm currently are using just crashes as soon as I try to
send or receive a #, independent if it is excaped or not...
If there is no example with #, do anyone know of any other example about
provisioning like this? Is there some kind of "defacto-standard"?
Regards,
// Andreas
