Neax AD-120 dropping calls

[tcjim]

Hi,
We have a NEC 2000IPS (R12.2) and a Neax AD-120 (2.8)and have just recently started using "Call Handler" options to route calls to various depts. Our problem is that incoming calls routed thru the AD-120 "Call Handler" are dropping after being transfered when the ext is busy. No answer is OK. Internal call forwarding "busy" or "no-answer" to the same ext is OK, calls go to Voice Mail normally. I am new to the AD-120 system and have checked everything I can think of. Did not find a forum for jsut the AD-120. Hope this makes sense. Thanks.

That is a lot of VM for an IPS but a quick question would be on the release type and how it is set coming out of the VM. If set to await answer then the call might get dropped because of that. The Ad-120 might need to be set to release in order for it to handle an immediate call back from the Phone in question. Also consider this is that phone set up to roll to a virtual extension first that appears on the same extension. If not have the Busy condition roll to a secondary roll over and then back to VM on a no answer the J record will still follow. Hope this helps

sounds like you may need to check the tone files.
the ad-120 will need to know the 'patterns' of each tone, ring back, busy, fast busy etc... to know how to interpret the call.
sound like you need to engineer to verify all toned are recognised properly.

Hi, just saw these responses...thanx. I ended up working with NEC direct on this. They claimed it was a known flaw in the "blind Xfer" over CCIS ( I did forget to mention that we have two sites routing over CCIS ) The AD-120 is set to release the call to the switch and I'm not sure I agree with NEC because it is only calls thru the AD-120 that drop. NEC says the AD-120 and CCIS are both programmed correctly. Calls transferred between our sites independent of the AD-120 work fine. I did create virtual rollover lines for the stations in question and this does help.
Checking Tone files is an interesting idea.
