Bug #99136 for Net-SIP: SIP Headers

Subject:	SIP Headers

Hello, I’m trying to use Net::SIP::Simple to make some automated calls for our monitoring platform. I’ve hit an issue whereby the Call-ID header is sent as “Call-id” (no capitals on the ID part) which is ignored by the SIP Proxy we’re talking to. I’ve had a read of the RFC which suggests it should have capital ID: Call-ID = ( "Call-ID" / "i" ) HCOLON callid callid = word [ "@" word ] I’ve had a look but can’t find a way to change this (I tried adding a custom Call-ID header which ended up in the same format) - Is there any way to change it or is this a bug? Thanks, Ben. -- Ben Sadler Systems Engineer Zen Internet Main Switchboard: 01706 902000 Fax: 01706 902170 Web: zen.co.uk We are Which?

I would not consider the field names as written in RFC3261 as suggestions on how to write the name. Nothing in the RFC says that there is a preferred writing at all. Instead it says clearly at page 31: "When comparing header fields, field names are always case-insensitive." Show quoted text

There is no way to change it except changing the code. But I consider this not as a bug in Net::SIP. Instead it is a bug in the SIP proxy which does not adhere to the RFC, because it does not compare field names case-insensitive. Regards, Steffen
