[Serusers] SER Proxy auth

[E. Versaevel]

OK, I'm a bit further now, my problem only occurs when using non numeric
usernames, ie if I use 1234 at host it remains 1234 but if I use erik at host it
turns into asterisk at host

I have to authenticate on each outgoing call, so I've setup SER+Asterisk,
however I still have some problems.
I already asked this on the asterisk mailing list, but I'm not getting any
replies there.

Ser forwards outgoing calls to asterisk, which authenticates itself to the
carrier proxy, so far so good. However, asterisk has to forward incoming
calls from the carrier to SER for routing to the UA's, however, asterisk
alters the from header in the sip messages, this way when someone adds the
incoming call to the address book, the sip uri is wrong and the call won't
get anywere.

Take a look at this sip msg:

	INVITE sip:erik at localphone:5061 SIP/2.0
	Max-Forwards: 10
	Record-Route: <sip:3400009521 at ser.box;ftag=as3f718642;lr=on>
	Via: SIP/2.0/UDP ser.box;branch=z9hG4bK93dc.71ad80b3.0
	Via: SIP/2.0/UDP ser.box:5065;branch=z9hG4bK513b584d
	From: "3400009525" <sip:asterisk at ser.box:5065>;tag=as3f718642
	To: <sip:3400009521 at sip.ser.box>
	Contact: <sip:asterisk at ser.box:5065>
	Call-ID: 533cb84a48058ebb71fbd7bf7557c0f0 at ser.box
	CSeq: 102 INVITE
	User-Agent: Asterisk PBX
	Date: Thu, 18 Nov 2004 12:46:51 GMT
	Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER
	Content-Type: application/sdp
	Content-Length: 220
	P-hint: USRLOC

As you can see the from user is not correct, this should be
3400009525 at iptel.org. If a user adds this entry to a phonebook, the contact
info will be wrong.
For outgoing calls this won't be a problem as I only send calls to the pstn
thru asterisk, incoming is a bit troublesome.

If you are using asterisk just for the purpose of registering with the
gateway then you could also consider using sipsak for that (that should
be simpler).

sipsak can send the registration and you can configured it to put the IP
address of your proxy server into the Contact.
