= SMS and calls theory =

If the incoming SMS delivery calls have a caller ID in the [https://www.bt.com/content/dam/bt/help/legacy-ug/new-pdf/BT%20SMS%20Text%20service%20centre%20numbers.pdf BT Text], the chances are there that it understands [https://www.etsi.org/deliver/etsi_es/201900_201999/201912/ ETSI ES 201 912], and for incoming SMS, refers to the caller as the SM-SC and recipient as SM-TE, or use the implementation [https://wiki.asterisk.org/wiki/display/AST/Application_SMS in Asterisk]

Line 23:

# As with "annex A.1" If caller-id is not witheld, answer the call, in the SM-SC role

# Log the outgoing SMS if required and transmit onwards

= Experimenting =

Trying to send SMS from Vodafone to a BT number ported to AAISP does result in text-to-speech calls that come from 08456021111, which is different from the numbers in gigaset sl450a-go that is use to get calls, so there likely be no need to support both the text to speech and FSK based SMS delivery.

The factory numbers are 1740P17094009* to send (as in active send=yes) and 0800587529* to receive (as in active send=no), it can be set to process these numbers on IP1 instead of "Fixed"

The asterisk apparently means to accept any follow-on digits, although it could mean asterisk literally also.
