h1. Using your SIP account

First [[SipDeviceConfiguration|configure your SIP device]]

h2. Incoming calls
6 66 Adrian Georgescu
7 79 Adrian Georgescu
When you enroll a SIP account on SIP2SIP infrastructure, a SIP address under @sip2sip.info domain is automatically allocated to you. You must provide this SIP address to those that want to reach you. Then you must have your SIP device registered with SIP2SIP infrastructure.

h3. Calls from PSTN network 
10 113 Adrian Georgescu
11 113 Adrian Georgescu
As you own a publicly reachable SIP address, you may receive calls from any SIP device that knows your address including a PSTN gateway.  You can receive calls from PSTN if you own a telephone number (not provided by SIP2SIP) and if the SIP gateway provider that handles that number can translate that number into your SIP address. Technically, if you number is in ENUM e164.arpa or e164.org trees you can simply map your ENUM number to your SIP address yourself. Any ENUM ready gateway will be able to automatically find the SIP address you configured for your ENUM number.

h2. Calling Out
14 66 Adrian Georgescu
15 1 Adrian Georgescu
Using your SIP device you can call any other SIP address reachable over the Internet in the form of user@domain. If you use a SIP enabled phone featured only with a classic 12 keys keypad you will experience a crippled service as is either impossible or hard to dial other SIP addresses with it.

h3. Calls to PSTN network 
18 1 Adrian Georgescu
19 113 Adrian Georgescu
Calls to PSTN are possible to SIP accounts under @sip2sip.info domain. If you have used your own Internet domain, it is not possible to call out to PSTN. You can call to the classic telephone network (a.k.a. PSTN) after you have purchased credit. Price list for dialing to PSTN destinations is available "here":https://mdns.sipthor.net/sip_rates.html. The call costs are logged in the Credit section of your "SIP settings page":http://x.sip2sip.info. To add credit to your SIP account at http://x.sip2sip.info?tab=credit 
20 113 Adrian Georgescu
21 113 Adrian Georgescu
To dial a PSTN destination dial + or 00 in front of the actual number including country code. The number must be a fully qualified E.164 number (country code + network number + subscriber number). First an ENUM lookup is attempted. If a SIP destination is found, the call will be routed to it, if ENUM lookup does not return a valid SIP address, the call is directed to a PSTN gateway.  To set your caller id please open a ticket in the support interface. Caller id presentation works depending on the support for this feature of all intermediate gateways to the destination, it is not possible to guarantee its working.
22 113 Adrian Georgescu
23 113 Adrian Georgescu
To limit fraud in case of lost account credentials, a maximum of 2 simultaneous calls are permitted. If you need more, please ask our support.

h2. NAT Traversal
77 1 Adrian Georgescu
 
78 1 Adrian Georgescu
Practically you do not need to set anything special in the client, NAT traversal is solved automatically by the SIP2SIP server infrastructure. We recommend actually that you check to have disabled all client features related to NAT traversal:
79 66 Adrian Georgescu
80 66 Adrian Georgescu
# Disable STUN as is unreliable  and leading to unexpected results
81 1 Adrian Georgescu
# Disable any SIP ALG support in the border router, most of the so called 'SIP enabled' routers on the market today are "simply broken":http://www.voip-info.org/wiki/view/Routers+SIP+ALG
82 66 Adrian Georgescu
83 1 Adrian Georgescu
Beware that corporate firewalls that have an explicit policy against SIP or poorly implemented "SIP ALGs":http://www.voip-info.org/wiki/view/Routers+SIP+ALG may still block your SIP signaling and/or media traffic. You need un-restricted access to the following ports used by SIP2SIP infrastructure:

h2. Presence
110 66 Adrian Georgescu
111 61 Adrian Georgescu
SIP2SIP provides a SIP presence agent that handles SUBSCRIBE and PUBLISH methods for presence events.
112 66 Adrian Georgescu
113 66 Adrian Georgescu
# To publish your presence send PUBLISH for *Event: presence* to your own SIP address, containing the body describing your presence information in PIDF format
114 1 Adrian Georgescu
# To subscribe to a SIP address, send a SUBSCRIBE message for *Event: presence*
115 66 Adrian Georgescu
# To subscribe to a list of SIP addresses (a.k.a. rls-services), send a SUBSCRIBE message for *Event: presence* containing an extra header: *Require: eventlist*
116 66 Adrian Georgescu
# To monitor who has subscribed to your presence information you must send SUBSCRIBe for *Event: presence.winfo* to your own SIP address
117 66 Adrian Georgescu
# To allow others to subscribe to your published information you must use XCAP protocol for manipulating *pres-rules* policy document 
118 1 Adrian Georgescu
# To store your buddy list on the server you must use XCAP protocol for manipulating *resource-lists* and *rls-services* documents
