Anthony,

Thanks for answering...and sorry for the delay.  I've already checked all of the ptime settings I can, and all phones plus freeswitch are set to use 20ms packetization.  I've even set "scrooge" in the codec negotiation, but I keep running into this issue.  I've updated my post with "sofia global siptrace on".

I am assuming that the ptime issue happens around line 2462 (http://pastebin.freeswitch.org/16935)

  1. 2011-08-01 09:12:37.332892 [DEBUG] sofia_glue.c:4711 Audio Codec Compare [PCMU:0:8000:20:64000]/[PCMU:0:8000:30:64000]

  5. 2011-08-01 09:12:37.332892 [DEBUG] sofia_glue.c:3042 Audio params are unchanged for sofia/internal/sip:1003@10.0.1.205:5060.
  6. 2011-08-01 09:12:37.332892 [DEBUG] sofia_glue.c:3052 sofia/internal/sip:1003@10.0.1.205:5060 Setting audio receive payload in Re-INVITE to 0
Could this be an issue with the Aastra'a firmware?  Or maybe the MOH is being processed at 30ms instead of 20ms, and the negotiation is not updated somehow?

I don't mean to sound ignorant, but I'm really at a loss here...and thanks again for any help!

Cheers,
Chris

probably ptime related thing.
you should have included the sip trace "sofia global siptrace on"
