asterisk users - Apr 2008 - Jitter buffer not used in SIP -> chan_local -> ZAP path even with /nj for local channels

Hi,

Asterisk 1.4

Working (jitter buffers created as expected):
ZAP -> SIP
SIP -> ZAP

Not working (no jitter buffers created):
SIP -> chan_local (with /nj) -> ZAP
SIP -> chan_local (with /j) -> ZAP
SIP -> chan_local (with no flags) -> ZAP

I have this in zapata.conf:
jbenable=yes
jbforce=no
jbimpl=fixed
jbmaxsize=300

Is there something I haven't tried that will make this work or will I have
to change my dialplan so it doesn't use local channels?

Thanks,

Mike

PS, here are some pages that I have used as sources of information:

	No mention of /j for local channels

	Nothing about local channels

	Mentions /j for local channels to apps
