Sip-implementors Subject: [Sip-implementors] Multiple Colon (:) as Header
delimiter of name-value Message-ID: Content-Type: text/plain;
charset="utf-8" Hi, I have a specific problem relating to SIP header
format. A UAC is sending Call-ID Header in INVITE as below Call-ID: :
vat4082403130ofbcghefckco...@mscsma1.ims.mnc007.mcc748.3gppnetwork.org My
UAS is sending 180 Ringing response as Call-ID:
vat4082403130ofbcghefckco...@mscsma1.ims.mnc007.mcc748.3gppnetwork.org
Notice the two colons in UAC request. In the response my stack is ignoring
additional Colon(:) but the response is rejected by UAC. I am perplexed as
to if colon(:) can be a part of Call-ID value or if two Colons(:) can occur
sequentially delimiting Header name and value. If someone can point me to a
Section of RFC, it will be very helpful. Thanks in advance, Gaurav Khare

Trying to anticipate and work around problems with other people's 
implementations is a futile game. You will never be able to anticipate 
all the stupid things people do. Given the syntax of the call-id header 
field, why is colon any more special than any other character allowed in 
"word". If you look at the comments in the abnf they explicitly say that 
they are trying to allow as much as possible.


Thanks,

I agree that colon is allowed in call-id, but whitespace is not. So it
appears to me that the UAC has erred.

Exactly what the UAS should do in this case is not defined. I would
suggest you either:

1) reject the request with a 400 response
2) ignore the error and use the call-id as-is

The fact that your uas ignored the colon suggests to me that its parser
is acting in an unjustified way. (Ad hoc parsing?)

         Thanks,
         Paul

Re: [Sip-implementors] Multiple Colon (:) as Header delimiter of name-value

[Maxim Sobolev]

Paul, there is no space between colon and the rest of the call-id in the
original example provided. So UAC seems to be doing the right thing I think.

Call-ID: :VaT4082403130oFbc
...
