6.3 configurazione gateway inserimento 

cloud gateway isdn

Company Indicates the company name of the gateway.
Select an interface type to which the gateway is connected.
  • VOIP: VoIP server or operator (e.g. VOIspeed 6)
  • WAN: indicates a route between two servers
  • ISDN: indicates an ISDN gateway (e.g. Mediatrix)
  • GSM: indicates a GSM gateway (e.g. V-6021)
  • Analogue: indicates a FXO gateway (e.g. V-6019)
In the name field, enter a name for the VoIP gateway. 
LinesSelect total number of lines that gateway can handle. See below the examples of gateway and associated lines to them:
  • ISDN 2:  Select 2 lines from the drop down field, if you have 2 ISDN lines or 1 BRI.
  • ISDN 30: Select 30 lines from the drop down list, if you have 30 ISDN lines or 1 PRI
  • GSM:  Select 1 line for each inserted SIM in the GSM gateway.
  • Analogue: Select number of lines depending upon the connected analogue line to the Patton box (e.g. if you have 2 line connected to 4 port Patton box then you need to select only 2 lines).
  • VoIP:  VOIP lines vary accordingly to the available bandwidth you have in the office.  You can select the VOIP lines after calculating the bandwidth required against the number of channels. (e.g. G.729 codec uses compressed method for every single call and requires 20 Kbps where as G.711 a uses uncompressed method and requires 80 Kbps). If your VoIP operator has assigned the number of lines on your account then you need to select the same number of lines as assigned by the operator.
EnabledYou can enable or disable the gateway by selecting the enable field.
Outbound numberOutbound number allows you to specify the output number as Caller ID when call is made over this gateway and enables you to display the whichever number you wish to be displayed, as lon as it meets the requirement set by the VoIP provider.
Possible options are as follows:
  • Username (as set by the provider): If selected then caller ID set on the account will be used for every call made.
  • Static: If selecting static then you can enter the number in set static number field which will be used as caller ID.
  • Calling: If selected then number set in the user profile will be used as caller ID.

Note:The number set as Caller ID must be a geographic number provided by the operator. You can display other number not provided by the operator by having number ported to the provider and by submitting the required documents. For example you can set different number other than Caller ID set on the account by setting the number in the user profile.

Proxy Depending on the VoIP provider, you can type the gateway IP address followed by the SIP port or domain name of the gateway.
DomainEnter the domain name of the gateway if you are configuring the VoIP gateway (e.g.
SIP id Enter the SIP ID provided by the VoIP provider. Usually the SIP ID corresponds to the account number provided by the SIP/VoIP provider.
RTP flow follower Some SIP providers allow peer-to-peer communication between an IP phone and thier gateways. When this feature is enabled on the SIP trunks, you can select the option "RTP flow follower" to avoid that the vocie traffic (in the RTP packets) flows through the PBX once the call is established.
Request Authentication You can enable authentication depending upon whether the gateway requires authentication or not. Authentication parameters are realm; username and password and these are provided by the VOIP provider.           


cloud gateway prefix

Advanced settings allow you to add or remove the prefix against the numbers dialled by the users. You can write rules to add or remove the prefixes in the advanced settings section.You can also write more than one rule and each rule must have the following syntax:

P1, P2, P3, where P1 = the called number prefix, P2 = prefix to be removed and P3 =prefix to be added. The comma works as a separator, so if you do not want to add or remove the prefix then there is no need to write anything in their field but you must leave the comma as separator to finish the syntax.This is a useful feature to bind the gateway by prepending a prefix to the dialled number. The prefix should be removed after the call is diverted to the gateway,otherwise the carrier will consider the dialled number as a wrong number.

Example: To route the call to Gateway A by dialling 51 as prefix(e.g 5101727848186), you need to enter the rule 51,51, (last comma shows that last field is empty) in the advanced settings section of the gateway. In this way when number is dialled with prefix 51 then call is routed to the carrier without prefix 51.
