Had a look through google/wiki but cannot find anything relating to removing 'ptime' from the SDP.

There is a few sections on rewriting SDP, but not sure if this would work as expected;

http://wiki.freeswitch.org/wiki/Codec_Negotiation#Rewriting_SDP

http://wiki.freeswitch.org/wiki/Codec_Negotiation#Modifying_the_codec_when_using_proxy_media_mode

Perhaps give those a try and see how you get on - in the mean time maybe someone else might reply with a better answer.
