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?
4-digit numbers are locally registered IP Phones. Route pattern for 5-digit numbers (XXXXX) points to PBX via Voice GW.
> you can dial onhook and then press dial, that avoids IDT. that's the reason why redial works
When I do so (dial onhook and then press dial) the process goes EXACTLY like off-hook dialing (I hear digits being dialed and then wait for T302 timeout)! ONLY redial works. May firmware be the reason of that problem?
Current firmware is (one of them, not sure which one)
