Re: [Sip-implementors] From/To header manipulation
RFC 3261 mentions that From/To headers, without the tag, can be changed -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, December 13, 2006 8:57 AM To: sip-implementors@cs.columbia.edu Subject: [Sip-implementors] From/To header manipulation Hi, Can we change the From/To header value (caller id part and not from tag) after dialog is established. My understanding is except tag anything can be changed in From header. We have requirement to show different caller id in case of transfers where A is first connected to B so A will have B's id in To header and when A is finally connected to C it should show C's id. How can we communicate using From and To headers only, many phones are not supporting P-Asserted Identity header for this purpose.

Re: [Sip-implementors] From/To header manipulation
RFC 3261 mentions that From/To headers, without the tag, can be changed The rfc3261 indicates To/From uri's currently cannot change because of backward compatibility with rfc2543. However it does indicate that this backward compatibility requirement might be deprecated by a subsequent RFC. The following draft provides an example related to the deprecation. http://tools.ietf.org/wg/sip/draft-ietf-sip-connected-identity/ -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, December 13, 2006 8:57 AM To: sip-implementors@cs.columbia.edu Subject: [Sip-implementors] From/To header manipulation Hi, Can we change the From/To header value (caller id part and not from tag) after dialog is established.
