Hi, when FS calls to a natted user, it generates an INVITE with a Request URI
as follows:
INVITE sip:user@XX.XX.XX.XX:XXXX;transport=udp;received="XX.XX.XX.XX:XXXX" SIP/2.0
Well, this is not valid since a SIP URI parameter cannot contain quote symbol (").
You can verify it in RFC 3261 - page 222 (look for "other-param"):
------------
uri-parameters = *( ";" uri-parameter)
uri-parameter = transport-param / user-param / method-param
/ ttl-param / maddr-param / lr-param / other-param
transport-param = "transport="
( "udp" / "tcp" / "sctp" / "tls"
/ other-transport)
other-transport = token
user-param = "user=" ( "phone" / "ip" / other-user)
other-user = token
method-param = "method=" Method
ttl-param = "ttl=" ttl
maddr-param = "maddr=" host
lr-param = "lr"
other-param = pname [ "=" pvalue ]
pname = 1*paramchar
pvalue = 1*paramchar
paramchar = param-unreserved / unreserved / escaped
param-unreserved = "[" / "]" / "/" / ":" / "&" / "+" / "$"
-------------
This causes Twinkle sofphone droping the incoming request since it's malformed.
Quote symbol (") should not be used in a SIP URI parameter in order to be SIP
compliant.
Since I just use Twinkle (the best and more SIP compliant softphone for Linux) I
can't test FreeSwitch for now :(
Best regards.
