The call continues fine.

Is it right that there is no codec info in the reply and the call continues?

The value for 18 is defined in some RFC as being G729/8000 so there's no
real need to redefine it in the SDP, especially not since the answering
party already knows that the initiating party also uses the same value.

Unless the offeror has reassigned 18 to a different payload type, which is technically allowed but a terrible idea, so you likely won't ever see it in practice :-)
