[Sipsak] Change forward number on SIP server....

[Lennart Hansen]

Hi,

I have a question about changing a forward number on a SIP server,
I hope this is the right place to go with questions like this
otherwise i'm sorry about the inconvience.

Anywho, the thing is, at work i can connect with this MXIE client and
change the number i forward to, it would however make my life so much
easier if i could do this though a cronjob and sipsak instead.

the HW in the other end is Zultys MX250, but it should be SIP
compliant as far as i could find out.

I think my biggest problem is I don't fully understand the SIP / SDP
protocol, and find it hard to find any real good information on how to
manipulate any variables through this protocol, with or without
sipsak, also it's in general pretty confusing.. Not as easy and
stright forward as HTTP or SMTP... :-)

I would really apperciate link's for reading material you might think
i would need to read to fully understand this, and links for docs on
the specifics on how to manipulate SIP servers in this extend needed
here.. examples are also most welcome...

Thanks in advance,
