[Freeswitch-users] wrong ptimes and second SDP!, cough cough Thomson ST2030

I have a Thomson ST2030 VoIP phone that seams to be sending wrong ptimes. The SDP says 20 ms when it should be sending 10 ms. Freeswitch *cough cough* algorithm is able to set the soft timer for 10 ms... but when another SDP arrives (after approx. 30-40 seconds) the ptime is set back again to 20 ms. I am using 1.0.5 and it seems a bug in Thomson SIP stack. Any work around? -- Stopping junk mailers is good for the environment
