Hey All So here is the scenario,
If party A calls party B and party B has a mobile phone, desk phone and PC, the call will get forked to all devices and the PC may answer. The GRUU for B's PC is stored on device A. If B had a sequential ringing scheme whereby the mobile phone rang first, then the desk phone, then the PC, then this scheme would be lost at the next time that party A called party B, as the party A may decide to insert the GRUU for the next communication with party B, thus contacting the PC. This would override any ringing/contacting preferences for party B. So that is the background for this question. The question I pose is: * If the network decides to 'override' the GRUU usage by enforcing the ringing preferences for party B, then the network may Hold the communication between party A (using party B GRUU) and notify party A of unavailability to complete the communication path based on existing callee capabilities i.e. using party B GRUU. Party A may then re-initiate (using SIP UPDATE) communication with party B by not including party B GRUU. * Is it possible to use UPDATE in such a manner to change the Contact header within the Invite dialog?
