A siptrace would be helpful.

Can you peovide the call flow information as it relates to the
gateway? i.e. Is it going through a pstn or itsp provider?

The siptrace would help define what codecs are being offered/accepted.
A call using h.264 uses the same media ports as a voice only call. So
it could be a gateway or endpoint that is not offering or allowing
video. Hence the siptrace.
