SIP Capture Example

Use SIP capture examples to diagnose peering, trunking, caller ID presentation, and billing header issues.

SIP capture helps diagnose how calls are being presented to 2talk. This is most useful for SIP peering, trunking, caller ID presentation, and billing header issues.

SIP peering recap

SIP peering connects your IP PBX to 2talk using a trusted static WAN IP address. Registration uses a username and password instead.

After peering is enabled, 2talk allows traffic from your approved WAN IP. You should also restrict SIP access on your firewall to the 2talk SIP range.

Peering modes

  • Global Peering: Routes account traffic to one nominated WAN IP.
  • Standalone Peering: Routes one number to one nominated WAN IP.
