Hi!
A service in a SIP network that performs redirection (as a terminating
service for a subscriber), how does it preserve redirecting data?
Example: A calls B, B has in its domain enabled an application server that
will redirect the call to C (not using 302). Application server is a B2B so
it is allowed to change any header.
In the sipmessage sent to C, is it possible to find the following
information?
- Called Party Address/Number (the number/address of C), address will be in
request uri, but where can a tel URI be stored?
- Calling Party Number/Address (CLI of the original caller, A)
- Original Called Party Number/Addrss (original dialed number/address B)
- Redirecting number/address (the one that made the redirection, B)
- Redirecting counter(how many times this call has been redirected)
In ISUP, there are paramters for these values, how about in SIP? Does
someone know about a draft or RFC where I can find more information? To
solve it I guess I can use SIP-T but is there any other solution?
Regards,
// Andreas
