Analog line ringing

Hello,

I have a VIC-2-4-FXO that has two issues. 1) there seems to be a 30 second  delay from when the caller hears ring back to when the IP set actually rings. 2) If the caller hangs up without being answered, the IP set keeps ringing for about 20 secs. Don't know what timmers to adjust.

Use connection plar opx for better results.

Hi Pat,

In additon to my firend Paolo's great tips (+5 "P" )

connection plar opx immediate

FXO Delayed Caller ID Delivery

Before  Cisco IOS Release 12.4(11)XW, Foreign Exchange Office (FXO) Caller ID  in North America was delivered between the first and second ring cycles  based on the Telcordia GR-30-CORE standard. FXO software was configured  to wait for Caller ID delivery before initiating the call setup for the  next leg. As a result, the destination endpoint did not start ringing  until after 1.5 to 2 ring cycles on the FXO port.

Beginning  with Cisco IOS Release 12.4(11)XW, the immediate keyword is added to  the connection plar opx command. When this keyword is included in the  syntax, the FXO port sets up calls immediately so that the ring-cycle  discrepancy is eliminated, and the perception of the number of rings is  the same for both the caller and the called party. When the Caller ID is  available, it is forwarded to the called number. If the called party  answers the call before the Caller ID has been forwarded, then the  Caller ID update will not be forwarded to the display at the called  party.

--------------------------------------------------------------------------------

Note  This feature does not require that Caller ID be enabled. If Caller ID  is enabled, it is handled as described here. The fundamental benefit of  this enhancement is to ring the destination party immediately.

--------------------------------------------------------------------------------

This  feature is critical for service organizations that have service level  agreements (based on calls being answered within a specified number of  ring cycles) with their customers.

From this good doc;

Thanks that fixed the incomming ring.

If an incomming caller hangs up before being answered, the IP sets keep ring for about 15seconds. Would you happen to know what timer would need to be changed?
