This document describes how to configure a different calling number for each campaign when you use the outbound Session Initiation Protocol (SIP) Dialer. This allows your customers to see a different calling number based on the campaign that is used.
Your service provider must accept the calling number configured. Some providers only accept a calling number in the range of your Direct Inward Dialing (DID) numbers.
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
In the Configuration Manager, navigate to the Outbound Option Campaign. In order to configure the Caller ID (CLID), enter the number in the Campaign prefix digits field.
The SIP Dialer adds this number to the outgoing INVITE in the Remote-Party-ID header. Enter this command on the gateway (GW) in order for the GW to send this number to the provider:
If a Remote-Party-ID header is present in the incoming INVITE message, the calling name and number extracted from the Remote-Party-ID header are sent as the calling name and number in the outgoing setup message.
In order to verify this process, collect these logs on the GW:
- debug ccsip messages
- debug isdn q931
You should see the Remote-Party-ID header with the value configured in the Campaign:
INVITE sip:firstname.lastname@example.org SIP/2.0
Via: SIP/2.0/UDP 10.48.54.193:58800;branch=z9hG4bK-d8754z-585af41448265640-1---
CSeq: 1 INVITE
Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, UPDATE, NOTIFY, PRACK, REFER, NOTIFY,
Supported: timer, resource-priority, replaces
This is what is sent to the provider in the outgoing setup message:
Sep 16 13:00:55.204: ISDN Se0/1/0:15 Q931: TX -> SETUP pd = 8 callref = 0x0083
Bearer Capability i = 0x8090A3
Standard = CCITT
Transfer Capability = Speech
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA9839F
Exclusive, Channel 31
Calling Party Number i = 0x2180, '123456789'
Called Party Number i = 0xA1, '6611112'
There is currently no specific troubleshooting information available for this configuration.
