[Sipsak] Problem with From header

Wed Feb 1 15:54:24 CET 2006

Hi Klaus,

sorry for the late reply, I was very busy during the last days.

I agree with you that this behavior of sipsak is a little bit problematic. For 
a REGISTER it is clear that you need only one account (except for third party 
registration). But for all the other tests like INVITE's, MESSAGE's, OPTIONS 
etc. you would need a second account for the From. Now you could just try to 
use the same account for From and To. But I fear that this would lead to 
problems in many setups as well.

But to solve your Problem: you could try the option -c which set the From uri 
to the given value. I added that option recently to have more reasonable 
sender for the short messages. So you could just set it to the same value as 
the destination URI if that works for your setup.

Greetings
  Nils
