The example you gave with the value of +sip.instance between double quotes is valid, I have seen it many times like this.
On the other hand, other parameters of Contact header can usually be without quoted value, like:
Contact:sip:user@domain;reg-id=1
Both types can be in the header at the same time.
Is the value with double quotes making troubles somewhere?
Cheers, Daniel

Thank you for your answer. The green example was just for testing. My real example is similar to yellow on a header parameter since i have a client sending me the value of sip.instance between quotes and i can't identify the value when it is quoted.
Example : Contact:sip:user@domain;+sip.instance="urn:uid:00000000000000"
It seems to me be a valid sip parameter, but if it's not i'll warn the client

Hello, the values of parameters can be quoted or unquoted, depending on the format (e.g., URI parameters have to be unquoted). If they start with a quote, then it has to be terminated with the same quote and then the value is in between the quotes. The {param} transformation is using the same parser as for parameters in SIP message. Now, I am not sure if quote is allowed in an unquoted parameters like green, the grammar in SIP specs has to be checked... Cheers, Daniel On 08.10.19 16:09, Duarte Rocha wrote:Hi David. I want to ble able to print : yellow = "twelve". In the green example the "" are printed, but on the yellow example it is not.

Is this intended behaviour or should i submit it as a bug?
