Alexander Traud commented on ASTERISK-7803:
-------------------------------------------

??iLBC is still using a fairly low limit, as I do not have any way to test this codec.??

Here, this issue was fixed only partly with SVN [revision 43675|http://svnview.digium.com/svn/asterisk?view=revision&revision=43675]. It was never fixed for iLBC 30. The issue was introduced with SVN [revision 43243|http://svnview.digium.com/svn/asterisk?view=revision&revision=43243] and [Mantis-5162|http://bugs.digium.com/view.php?id=5162]. The mentioned asterisk-dev discussion can be found [here|http://lists.digium.com/pipermail/asterisk-dev/2006-September/023371.html]. Although, the discussion started in [Mantis-7978|http://bugs.digium.com/view.php?id=7978] actually.

9 years later, I was able to test higher packetization times (SIP/SDP ptime) with iLBC 30 in chan_sip. Please, see that attached patches.

> A discussion on -dev pointed out the the maximum framing values for 
> many codecs was set too low.  This patch increases the limits, while
> attempting to maintain headroom, for cases such as RTP over VPN or
> other encapsulation.
> VBR codecs iLBC and SpeeX are still using fairly low limits, as I do not
> have any way to test these codecs.  Testing and feedback about any codec
> is desired, but Speex and iLBC need the most love.
> ****** ADDITIONAL INFORMATION ******
> This is a trivial patch, so it should apply to both branches/1.5 and trunk
