Thanks Anders that works.

For my information I was trying to see if there was a preferred
way of getting dissection information from a 'encapsulating'
layer.

I'm almost done.

The last thing I'm trying to do (I think) is figure out if I
can add IOS5 to the VoIP calls analysis.

Hi,
How about having a handle per type :)

Yes, I have the following:

    dissector_add_string("rtp_dyn_payload_type",  "EVRC", evrc_handle);
    dissector_add_string("rtp_dyn_payload_type",  "EVRCB", evrc_handle);
    dissector_add_string("rtp_dyn_payload_type",  "EVRCWB", evrc_handle);

but when a particular packet is being dissected I want to know if it is EVRC or EVRCB or EVRCWB so that I can use different header fields.

Hi,
Have a look at pcaket-amr or pcaket-h264.c

But basically:
dissector_add_string("rtp_dyn_payload_type","AMR", amr_handle);

You can also do

Hello,

I have a dissector that gets called after RTP.

How can I get the payload type for the packet from the RTP dissection in my dissector ?

My dissector is called based on dynamic payload types.

Thanks
