[SR-Users] Error parsing parameter value

[Daniel-Constantin Mierla]

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 at 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
