Fwd: [Users] uri:host

[Ramin Dousti]

If you/someone could point me to a document as to how to manipulate the
SIP header programatically, I really appreciate it. All the documents I read
show  to set things with static values, for example, for send or forward it
shows forward("UDP:1.2.3.4:5060"), what if the decision making of what
protocol/dst/port should be used is a variable that should be determined
during the processing of the message itself. Let me give a concrete example:

I get a message destined for user at somedoamin.com, I need to be able to
determine the host for that domain, depending on what the host is I need to
use either TCP or UDP, besides let's say, somedomain.com resolves to
two IP addresses, I also need to try the first IP and if it fails (IP
connectivity-wise)
then I try the second one.

I really appreciate any pointer/assistance.
