SIP 484 Address Incomplete
SIP 484 Address Incomplete means the number is too short to route. Usually the call was sent before the whole number was dialled, or digits were cut off.
- Who sends it
- The SIP trunk
- When
- Placing the call (INVITE)
- Retry?
- Not until the full number is sent.
- The caller hears
- A failure tone straight after dialling, sometimes before you finish typing the number.
What causes 484, and how to fix it
484 means the number stopped short. The server could tell it was the start of a valid number, but not enough digits arrived to route it.
- 1Most common
The phone sends the call too early because its dialling timeout is short.
Lengthen the inter-digit timeout on the phone, or press # (or the send key) to send the number at once.
- 2Most common
The PBX dial plan strips too many digits before sending the call to the trunk.
Check the outbound route rules so the full international number reaches the trunk.
- 3Sometimes
The number was dialled without its country code.
Dial +, the country code and the number, or set your dial plan to add the country code.
- 4Rare
Overlap dialling is enabled, so digits are sent one by one.
Turn off overlap dialling on the trunk; SIP trunks expect the whole number in one request.
