Hi Ben,
thanks for this. It has been checked-in, SVN 180.

Hi all
I've noticed that when I use the [routes] keyword in a request, but there
is no route set (ie. the proxy did not record-route), then sipp inserts a
blank line (CRLF) in the SIP header, when it should insert nothing at all.
For example, if I send this ACK after receiving the 200 OK with no
Record-Route headers:
<send>
<![CDATA[
ACK [next_url] SIP/2.0
Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
From: "[caller]"
<sip:[EMAIL PROTECTED]:[local_port]>;tag=[call_number]
To: "[callee]"
<sip:[EMAIL PROTECTED]:[remote_port]>[peer_tag_param]
Call-ID: [call_id]
CSeq: [cseq] ACK
[routes]
Contact: sip:[EMAIL PROTECTED]:[local_port]
Max-Forwards: 70
Content-Length: [len]
]]>
</send>
... then the packet that actually gets transmitted looks like this:
ACK sip:192.168.0.19:5070;transport=UDP SIP/2.0
Via: SIP/2.0/UDP 192.168.0.19:5050;branch=z9hG4bK-1-3-15130
From: sipp <tel:2080001000>;tag=1
To: sut <tel:2080001010>;tag=1
Call-ID: [EMAIL PROTECTED]
CSeq: 1 ACK
Contact: sip:[EMAIL PROTECTED]:5050
Max-Forwards: 70
Content-Length: 0
The blank line looks like the end of header at the receiver, so the
message is truncated.
I've attached a patch I made to call.cpp in the sipp.2007-03-14 snapshot.
If there is no route set then no blank line is inserted. Perhaps this will
be of use to someone.
Cheers
Ben
