I found the "Auto DTMF" options active during call in my Trium Eclipse - works for both incoming and autogoing calls. It allows to search the phone book. as you described.
But...
1) You must search the phone book quickly - callback/calling card/callthru operator will not wait too long before disconnecting
2) The format of the destination number - that might a problem! It's usually recommeded to store numbers in GSM phones in the international format (with leading +). But, of course, this won't work for services under consideration (what is a DTMF tone for + ?). It will be OK if the calling card service and direct dialling (in areas where you want dial directly, I mean mainly home country) both support the common format like 00CountryCodeNumber - you can use entries in this format. But what about e.g. CBW - they require numbers with _nothing_ preceding the country code.
E.g. I can store my home landline number +4881xxxxxxx to be usable with Orange Poland SIM in one of the following formats:
1. 81xxxxxxx
2. 081xxxxxxx
3. 004881xxxxxxx
4. +4881xxxxxxx.

The format 1 and 2 are valid when I call from Poland only, 3 should work also in roaming countries with 00 "international exit code", and 4 of course is valid anywhere.

But if needed the same number to be used with CBW, I would have make a duplicate entry 4881xxxxxxx (or perhaps 4881xxxxxxx#). No so nice, if some would have to duplicate dozens of contacts... Of course, if I dialed directly 4881xxxxxxx, I wouldn't be connected in roaming (I suppose) and in Poland, the operator would try me to connect with the number +484881xxxxxxx (Polish area code 48, of course such a number doesn't exist - too long ).
