@curlycord, thank you for responding! unfortunately when I go into telset programming I already see that Call Forward No Answer is already set to the DN of Callpilot, which is 2334 for us. the ring count is also set to the default of 4. so to rewind and provide a bit more info on the current setup...
the handset is currently assigned DN 3310, such that anyone in the office can reach this handset via dialing 3310 on their own handset. handset 3310 can also reach other handsets via their DN so in regard this part works fine. somehow this DN 3310 is already assigned a phone number ending in 3310 and dialing this phone number actually works fine from inside or outside the office. the issue is that this phone number has an area code that we don't want to use so we want to have a second phone number assigned to it such that when you dial that phone number it also reaches this handset. right now when we dial this second phone number it DOES reach the handset, but after half a ring it immediately goes to the voice attendant. we have lines 201 and 310 assigned to this DN where 201 represents the second phone number and 310 represents the first phone number.
