Carriers¶
Carriers are used for placing external outgoing calls.
This are the fields that define a carrier:
Consejo
Some fields described below may not be visible depending on enabled features.
- Name
- Used to reference this Carrier.
- Description
- Optional field with any required extra information.
- Numeric Transformation
- Transformation that will be applied to the origin and destination of the outgoing numbers that use this Carrier (see Numeric transformations).
- Calculate cost
- If set, IvozProvider will calculate the cost of the call using the carrier’s active rating profile.
- Currency
- Chosen currency will be used in cost calculation, balance movements and remaining money operations of this carrier.
- Local socket
- Selected address will be used as source address for signalling with this carrier. Brand operator can choose among addresses assigned by main operator via Brands. Read Proxy Trunks for further details.
- Media relay set
- Media-relays can be grouped in sets to reserve capacities or on a geographical purpose. Selected set will be used in calls through this specific carrier. This field in only seen by Global administrator (aka God).
- Status
- Non-responding carrier servers are inactivated until they respond to OPTIONS ping request. This icon is green if every carrier server of given carrier is active, red if they are all inactive and yellow if just some of them are inactive.
Consejo
If you want carrier-side media handled by the same mediarelay set than client-side, select “Client’s default”.
Cost calculation¶
If Calculate cost is enabled, Rating plans can be linked to carriers for cost calculation (see Assigning rating plans to carriers) and a balance is attached to each carrier. Whenever a carrier is used for placing a call, this balance will be decreased using carrier’s active rating profile.
Besides:
- Carrier balance can be increased/decreased with Balance operations.
- These operations are listed in List of Balances movements.
- Balance notifications can be configured to be notified when balance reaches a given threshold.
Importante
Contrary to clients’ balances, carriers’ (negative/zero) balances won’t disable the carrier.
Carrier Servers¶
A Carrier Server is a SIP server associated to an IP Provider. Carrier servers are used for placing outgoing calls by using Outgoing Routings.
- SIP Proxy
- IP address (or DNS registry) of the Carrier Server. You can also specify a port if it’s different from 5060.
- Outbound Proxy
- Usually this is left empty. It can be filled with the IP address of the SIP Proxy domain (to avoid DNS resolution, but keeping the domain in the SIP messages). It works like a web proxy: instead of sending the SIP messages to destination SIP Proxy, they will be sent to the IP:PORT of this field.
- URI Scheme
- Supported schemes are sip and sips. Use ‘sip’ in case of doubt.
- Transport
- Supported transport protocols. Use ‘udp’ in case of doubt.
- Requires Authentication
- Some Carriers validate our platform by IP, others require each session that we want to establish. For this last case, this section allows to configure user and password for this authentication.
- Call Origin Header
- Some Providers get origin from SIP From header. Others use the From header for accounting and need extra headers to identify the origin. In case of doubt leave PAI checked.
- From header customization
- For those providers that show origin in other headers (PAI/RPID), it is possible that request that From User have the account code being used and from domain their SIP domain. In case of doubt, leave empty.
- Status
- Non-responding carrier servers are inactivated until they respond to a OPTIONS ping request. This icon shows if carrier server is active or inactive (and being pinged via OPTIONS message until gets back).
Truco
There are many fields to establish peering with multiple kind of carriers, but usually with the name and SIP Proxy will be enough (for those that validate our platform by IP) and Authentication (for those that won’t).
Advertencia
In case of defining multiple Carrier Servers for a single Carrier, IvozProvider will balance and failover using all of them. Like with Application Servers, it will disable those who doesn’t respond to our requests.
List of external calls¶
You can see external calls placed through a given carrier using this option. You will see the same fields as in External calls but filtered for the chosen carrier.
Error
It is compulsory to have a valid brand URL in order to use Export to CSV feature in this subsection.
