Summary:                    [patch] Setting registration expiry in registration
string does not work
Description: 
In some applications it is necessary for an asterisk pbx to have very short
registrations with a voip trunk provider if for example the asterisk pbx is
behind a nat firewall and the provider does not provide other udp binding
keep alive mechanisms.

According to sip.conf the format for the registration string is
[transport://]user[:secret[:authuser]]@host[:port][/contact][~expiry]
so that it should be possible to set a shorter registration by appending a
~ and an expiry value e.g. http://bugs.digium.com/view.php?id=22#c60 for a one
minute registration

However the chan_sip.c code does not seem to make use of the [~expiry]
portion so the default expiry value is always used for all registration
strings.

Assigned this to mnicholson as it should be a fairly straight forward patch
to get implemented.
