It may be your ATA equipment.
If, say, you have an analog terminal, connected to an ATA box (such as the Linksys PAP2T) or even a FXS card, that equipment *has to* wait.
The reason is, in SIP telephony, the number has to be processed all at once. Therefore, the ATA equipment waits long enough for you to complete the number.
Most of those boxes are configurable to that point. However, a small timeout may be annoying when you hold the handset and pause to read your phonebook further.
One other way is fixed-length dialing. Here in Greece, all numbers are 10-digit. Therefore it's easy to say: wait for 10 digits and then dial them. On the other hand, a2billing means you are dialing international. International numbers are all variable, rules there are too complicated to follow..
