Is it possible to rewrite the from uri?
For example when I [sip:tomas@krixor.xy.org] want to call a pstn
number I must rewrite the from address to
[sip:myphonenumber@krixor.xy.org] before I send the request to
the pstn gateway
That is quite tricky -- it is close to protocol breaking. The From header
field has been designed read-only in SIP. Nevertheless, this application
has been already asked for. I wrote a short text on how to do that for
those who wish to do so.

I'm beginning to see why this is a pain to do :)
Got it working 'kinda', the problem is not to change the From: adress but
to actually change it back when sending messages to the originating UA.
Do you have any example configuration for SER to do this? It looks like
you've done som testing in the area ? This is a feature
many people (anyone with a pstn-gateway) could use.
Something like a './serctl enum add phonenumber sip-user[(a)domain.com]'
that gets added to the sql database would be nice.
And a flag(X) to trigger the translation if the invite is coming
from/going to the pstn gateway.
