Mark,

This looks like a T38 Re-INVITE, but a weird one.

Hi All,

I'm sure I've discussed this before, but I searched through my gmail

and google and couldn't find the answer.

Below is the SDP parameters from my sip provider.  Is it mandatory to

always include the rtpmap details for PCMU/PCMA codes?  For example

something like 'a=rtpmap:8 PCMA/8000' and 'a=rtpmap:0 PCMU/8000'?

I'm using sipdroid on android and it rejects this with 'codec not supported'

Thanks
