Summary:                    Wrong encoding of SIP URI
Description: 
When callerid(num) of an incoming call has a # in the number the SIP URI is
not encoded properly.

Should be encoded as %23

A lot of phones just reject the call.

sip.conf, extension.conf and sip debug of incoming call uploaded
(testserver to make debug more simple).

I am using strings with a # for choosing the outgoing line. On incoming
calls I am preparing the number for callback by adding the strings.

It is working without problmes with Snom ore Linksys phones.

Testing Aastra phones I get "400 Bad Request" back from phone on incoming
call.

Talking to the support of Aastra I got the answer back, that # must be
encoded in sip uri.

Checking outgoing call from Aastra phone with # in the number shows
encoded uri.

From: "001707901706" <sip:1#001707901706 at 192.168.110.48>;tag=as24950318

According to http://www.ietf.org/rfc/rfc2396.txt the # must be escaped.
