1) CCM 4.1
2) Cisco IP Phone 7970
There is one route pattern XXXXX which points to voice gateway. There are 4-digit local DNs.
Therefore when I dial local number (e.g. 2001) using ip phone 7970 (DN: 2002), digits goes to CCM one-by-one and I have to wait until T302 (interdigit timeout) expires to get my phonecall processed. If I dial 2001# I hear busy tone right away.
On the contrary, when I dial <redial> button the call establishes immediately (digits does not go to CCM one-by-one).
Well, the question is: Is it possible to make IP phone dial all numbers immediately (one stage dialing)? Why # sign does not help?
Is it necesarry at all for IP telephony to use two stage dialing?
