add two missing entries in the replica of the sip_tech that

does not use  DTMF BEGIN frames.

1.4 seems correct (it does not have the two fields).

However, as this bug shows, the current way of creating the sip_tech
replica is too error-prone, one can easily forget to update one of
the two entries.  Perhaps it would be better to create sip_tech_info
expliclty at module load, by doing

	sip_tech_info = sip_tech;
	sip_tech_info.send_digit_begin = NULL

(in this case, this is something applicable to 1.4 as well).
