A SIP domain represents a grouping of devices (or users) that can communicate with one another.
+
−
You must configure SIP Registration Domain for your system. The first step in doing so is to create a SIP Domain:

== SIP Registration to SIP Proxy overview ==
  
 +
Telcobridges product supports registering a SIP NAP to a SIP proxy.
 +
*Registration authenticates Telcorbidges product's IP address to a SIP provider proxy or SBC and this will allow SIP traffic from the Telcobridges product to pass through to that SIP provider.
 +
*Registering to a SIP provider from Tmedia/ProSBC will always take place over SIP trunk.
 +
*SIP trunking enables the end point’s PBX (Private Branch Exchange phone system), Telcobridges product such as Tmedia or ProSBC, to send and receive calls via the Internet.

3- Create the new Domain:
+
*[https://en.wikipedia.org/wiki/SIP_trunking Wikipedia SIP trunking article]
−
 
+
−
* Enter a configuration '''Name''' for this domain.
+
−
* Enter a '''Domain Name''' for the SIP Registration Domain (domain can be a FQDN or an IP address)
+
−
* Set the number '''Maximum Registered Users''' for this domain
+
−
* Set the Expires value used by SBC when the remote device doesn't supply one ('''Default Contact Expire''')
+
−
* Select '''Routing Method''' the system will use to route calls to registered users (if enabled in routing scripts).
+
−
** '''Register source''': Sends SIP Invite to the registering source IP address.
+
−
** '''Contact''': Sends SIP Invite to the 'contact' from the Register message.
+
−
* Set the '''Default Contact Expiration''', this value will be used when no ''Expires'' value is supplied by the user agent.
+
−
* Set the '''Minimum Contact Expiration''', this is the minimum ''Expires'' value that can be supplied by a user agent. Lower values will be rejected with a 423 'Interval too brief' response.
+
−
* Set the '''Maximum Contact Expiration''', this is the maximum ''Expires'' value that can be supplied by a user agent. Higher value are replaced by this parameter.
+
−
* Forwarding Parameters:
+
−
** Select the Registration '''Forwarding Mode''' to the registrar:
+
−
*** '''Contact Remapping''': Changes the user and the IP address.
+
−
*** '''Contact Passthrough''': Doesn't change anything. Enables devices to be contacted directly without going through the SBC.
+
−
** Set '''Minimum Registrar Expiration''', this is the minimum ''Expires'' value sent by the SBC to the registrar.  If a user agent 'Expires' value is greater than this parameter, the SBC will do rate adaptation between the user agent and the Registrar.
+
−
** Set '''Maximum Pending Register Forward''', the maximum number of simultaneous pending register requests allowed for this domain.  New REGISTER request are being refused passed this threshold.
+
−
** Set '''Maximum Simultaneous Register Forward''', the  maximum number of simultaneous active register requests allowed for this domain. New REGISTER request are being refused passed this threshold.
+
−
** Select the Registration '''Registrar Selection Mode''' to the registrar:
+
−
*** '''Active/Standby''': The active registrar is the one with status up and the lowest priority (automatic fallback).
+
−
** Enable the '''Forward After Switchover''': After a switchover, the first register refresh request from each user will be forwarded to the active registrar.
+
−
* Click '''Create'''

* Click '''NAPs''' in the navigation panel

* Click on a NAP to bind the SIP Domain to

* Add the SIP Domain to the NAP (bottom of the page):

6- Multiple registrars (registration redundancy)
+
−
Multiple registrars can be created per domain, for redundancy.
+
−
* Registrars are ordered by priority
+
−
* Users' registration requests are forwarded to the available registrar with the highest priority in the list
+
−
* SIP 'options' polling is used to determine which registrars are available or not

== Create routes for registered users ==
+
−
In most cases, TBSC will be required to route SIP calls (SIP Invite) to registered users. That's done by [[Sip_registration_forwarding#SIP_Calls_routing|creating appropriate routes]].

SIP Registration to SIP Proxy overview

Telcobridges product supports registering a SIP NAP to a SIP proxy.

  • Registration authenticates Telcorbidges product's IP address to a SIP provider proxy or SBC and this will allow SIP traffic from the Telcobridges product to pass through to that SIP provider.
  • Registering to a SIP provider from Tmedia/ProSBC will always take place over SIP trunk.
  • SIP trunking enables the end point’s PBX (Private Branch Exchange phone system), Telcobridges product such as Tmedia or ProSBC, to send and receive calls via the Internet.


You must configure SIP Registration to a SIP Proxy (a SIP provider/ITSP) on Telcobridges product if it is required for above mentioned purpose.

SIP registration to SIP Proxy (NAP) can be configured in NAP editing page:

Setting SIP Registration to SIP Proxy in NAP configuration

  • Two required sections to set are: Registration Parameters, Authentication Parameters
  • Registration Paramters: need to obtain address to register from SIP Proxy/SIP provider
  • Authentication Parameters: check ignore realm use username and password, also specify the Realm, obtain this information from SIP Proxy/SIP provider
