| IOP1 | vendors eSBC response to SIP OPTIONS messages from SBC | No calls are required for this test. SIP trace to be captured for approx 60 seconds and checked for correct signalling.
For each eSBC, the SBC will periodically send an OPTIONS request to the vendors eSBC to check if its SIP stack is reachable. If a SIP response 200 OK is received from the IP-PBX, the SIP trunk will be placed (or remain) in an In-Service state. Example: OPTIONS sip:ping@<ip-pbx_IP_Addr>:5060 SIP/2.0 | Pass | |
| IOP2 | SBC response to SIP OPTIONS messages from vendor eSBC | No calls are required for this test. SIP trace to be captured for approx 60 seconds (depending on agreement) and checked for correct signalling.
