Then I suggest you pastebin your configuration, and debug-level freeswitch logs for the call, with sip tracing enabled so that we can see why PCMA isn't being used.

http://pastebin:freeswitch@pastebin.freeswitch.org/ and send the link here when submitted.

You won't be able to use G729 (it's either 18 or G729/8000 neither of which appear).

The 8 (PCMA) should work IF you have PCMA enabled. Check which codecs you're allowing.

Your FS might also be configured to leave the decision up to the destination if you're bridging, so check whether that endpoint supports PCMA too.

And if you're doing PCMA-G729 that will fail with incompatibile destination too unless you're using the commercial (licensed) version of mod_com_g729.

Ok. I found the RFC with all valid names (rfc3551, correct?).

Shouldn't it work anyway since "8" is specified in the "m" attribute?
(From RC4566: If an attribute is received that is not understood, it MUST be ignored by the receiver)

Omission of the RTP map is fine if its a standard number like 0, 8, 18 and such that are assigned.  What isn't valid is G.729a or G.729b both are 100% invalid.  There is no such thing in the specs.
