SCN-Branch Calls (Dead Air)

[psepulve]

All, Why would some calls from branch site(s) via an Small Community Network give "dead air' while being dialed?

I have a three component IP406 customer that is experiencing this issue. The customer has an ISDN-PRI circuit at the Main Site (IP406V1: 3.2(57)). Branch A (IP406V2: 3.2(57)) and Branch B (IP406V2: 3.2(57))use the ISDN-PRI for all external calls. Do not get me wrong... Callas do go out, but some calls just DO NOT provided ring. These calls are primarily cell phone end-points, but some are home phone numbers.

Does the IP Office component(s) provide ANY control of this scenario?

Thanks.

You can also try toggling the FastStart option on the IP Trunk.

Will also try Faststart parameter, but I read IPO Tech Tip 55: "VCM channels sometimes do not properly get allocated and de-allocated... Avaya recommends that Faststart be disabled.."

 

[tlpeter]

fast start is for non avaya ipphones so you don't need it

no question is ever stupid, but i've seen that before. yes, all three sites (main and 2 branches) have vcm cards set with appropriate channel settings per leg. i have the event scheduled for tonight. well update all after. thanks again for the excellant replies. it's great to know others have questions as well.
