C# Class SIPSorcery.AppServer.DialPlan.DialStringParser

This class builds a list of calls from a dial plan Dial string. The dial string is an evolving thing and depending on the type of dial plan it can take different forms. Some forms are specific to a certain type of dial plan, for example an Asterisk formatted dial plan can have a long list of options to pass in the dial string whereas in a Ruby dial plan there are more elegant mechanisms. Each different type of dial string needs to be described here or there will be processing errors as the different options get overlooked or forgotten. The original dial strings from the Asterisk formatted dial plans can only forward to a SINGLE destination and use a form of: Dial(username,password,${EXTEN}@sip.provider.com[,FromUser[,SendToSocket]]) The second iteration dial string commands can forward to MULTIPLE destinations and use a form of: Dial(123@provider1&provider2|[email protected]|provider4&456@provider5[,trace]) The From header processing involves special behaviour as it can be customised in different ways. The rules are: 1. By default the From header on the request that initiated the forward will be passed through, 2.

Méthode	Description
GetForwardsForExternalLeg ( SIPRequest sipRequest, SIPURI callLegURI, string customContentType, string customContent, string fromDisplayName, string fromUsername, string fromHost, CRMHeaders contact ) : SIPCallDescriptor	Can't be used for local destinations!
IsURIInQueue ( Queue callQueue, string callURI ) : bool
ParseAsteriskDialString ( string data, SIPRequest sipRequest ) : SIPCallDescriptor	Builds the call list based on the original dial plan SwitchCall format. This will result in only a single call leg with a single forward destination. Examples of the dial string in a dial plan command are: exten = number,priority,Switch(username,password,new number[,From[,SendTo[,Trace]]]) or sys.Dial("username,password,${dst}@provider")
ParseFromHeaderOption ( string customFromHeader, SIPRequest sipRequest, string username, string forwardURIHost ) : SIPFromHeader	The From header on forwarded calls can be customised. This method parses the dial plan option for the From header field or lack of it field and produces the From header string that will be used for forwarded calls.
ParseScriptDialString ( SIPRequest sipRequest, string command, List customHeaders, string customContentType, string customContent, string callersNetworkId, string fromDisplayName, string fromUsername, string fromHost, CRMHeaders contact ) : Queue>	Processes dial strings using the multi-legged format. Each leg is separated from the proceeding one by the \| character and each subsequent leg will only be used if all the forwards in the preceeding one fail. Within each leg the forwards are separated by the & character. Example: Dial(123@provider1&provider2\|[email protected]\|provider4&456@provider5[,trace])

ParseDialString() public méthode

Parses a dial string that has been used in a dial plan Dial command. The format of the dial string is likely to continue to evolve, check the class summary for the different formats available. This method determines which format the dial string is in and passes off to the appropriate method to build the call list.

public ParseDialString ( DialPlanContextsEnum dialPlanType, SIPRequest sipRequest, string command, List customHeaders, string customContentType, string customContent, string callersNetworkId, string fromDisplayName, string fromUsername, string fromHost, CRMHeaders contact, CustomerServiceLevels serviceLevel ) : Queue>
dialPlanType	DialPlanContextsEnum	The type of dialplan that generated the Dial command.
sipRequest	SIPSorcery.SIP.SIPRequest	The SIP Request that originated this command. Can be null if the call was not initiated by a SIP request such as /// by a HTTP web service.
command	string	The Dial command string being parsed.
customHeaders	List	If non-empty contains a list of custom SIP headers that will be added to the forwarded request.
customContentType	string	If set indicates a custom content type header is required on the forwarded request and it /// overrides any other value.
customContent	string	If set indicates a custom body is required on the forwarded request and it /// overrides any other value.
callersNetworkId	string	If the call originated from a locally administered account this will hold the account's /// networkid which is used to determine if two local accounts are on the same network and therefore should have their SDP /// left alone.
fromDisplayName	string	If set will be used the From header display name instead of the value from the originating SIP request.
fromUsername	string	If set will be used the From header user name instead of the value from the originating SIP request.
fromHost	string	If set will be used the From header host instead of the value from the originating SIP request.
contact	SIPSorcery.SIP.App.CRMHeaders
