CME Two Ephone-dns with One Number question

jjia · ‎12-10-2005

Hi,

The example on CME 3.2 administration guide (http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_guide_chapter09186a00802d2476.html#wp2185139) says that two ephone-dns with one number on two phones can roll over the incoming call to the 2nd phone if the first phone is busy or ring-no-answer.

There is no problem if the first phone button is busy, it will roll over to the 2nd phone. But how come to roll over to the 2nd phone if the first phone button is ring-no-answer? If it works, how to define the ring-no-answer timer?

Thanks,

JJ

If I am reading your question correct, your confusion is about what the ring-no-answer timer does is this situation?

With the exact configuration the adminstration guide is showing you, the ring-no-answer timer will tell the system how long to ring ephone-dn 13 before ringing ephone-dn 14. The ring-no-answer is configured globally as timeouts ringing (value) under telephony-service.

Hope this helps.

no,this timer will not help to roll over the first phone to the 2nd phone but just disconnected if there is no call-forward noan configured on ephone-dn 13.

"The ringing timeout is the amount of time a phone can ring with no answer before returning a disconnect code to the caller. This timeout is used only for extensions that do not have no-answer call forwarding enabled."

Also from http://www.ciscopress.com/articles/article.asp?p=401648&seqNum=2,it says that

"The dial peer hunting mechanism works only for hunt on busy. It does not provide hunting on no-answer timeout."

I think this is correct.
