[Serusers] Ser+Nat +Polycom phones

[Greger V. Teigre]

Never had any problem with digest auth, but yes, we had some problems with 
the IP address.
However, here is the top of a current (after firmware upgrade) INVITE from a 
Polycom:

U 2005/05/27 10:50:42.733599 nat:2631 -> ser:5060
INVITE sip:number at ourdomain.com;user=phone SIP/2.0.
Via: SIP/2.0/UDP 10.2.2.54;branch=z9hG4bK7323c8ac29B7807.
From: "Username" <sip:userid at ourdomain.com>;tag=9DFAF7D6-DB7B7E5B.
To: <sip:number at ourdomain.com;user=phone>.
CSeq: 2 INVITE.
Call-ID: b07f3daa-4ce9e980-6bf54d45 at 10.2.2.54.
Contact: <sip:userid at 10.2.2.54>.
Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, INFO, MESSAGE, SUBSCRIBE, NOTIFY, 
PRACK, UPDATE, REFER.
User-Agent: PolycomSoundPointIP-SPIP_300-UA/1.4.1.

As you can see, this is firmware 1.4.1.

Here's a REGISTER:
U 2005/05/27 10:56:36.553574 nat:2631 -> ser:5060
