Summary:                    [patch] No audio on calls from asterisk sip phones
to nortel set until dtmf from sip phone
Description: 
When placing a call from an Asterick SIP phone (X-Lite) to Nortel phone set
(M3903), no voice will pass until any key is pressed on the SIP phone. SIP
to SIP calls - normal. SIP to external phone - normal. Nortel to SIP -
normal. All permutations of calls pass audio immediately upon answer except
an sip to nortel.

Asterisk is behind Nortel Option 11c via PRI
Telco -> PRI -> Nortel Option 11c -> PRI -> Asterisk

Very new to Asterisk and VOIP and don't know where to start...Any
suggestions would be GREATLY appreciated.

You need to have the source for DAHDI also.

It will perhaps pay to find out your version, on a 1.6x system the
asterisk CLI command is 'dahdi show version'
or from outside of asterisk  dahdi_cfg --help

I hope this isn't a production box, or you know how to recover:
If you don't, then I don't suggest that you continue.

Below, guideline instructions:

cd /usr/src
svn checkout http://svn.digium.com/svn/dahdi/linux/tags/2.2.0 dahdi-linux
svn checkout http://svn.digium.com/svn/dahdi/tools/tags/2.2.0 dahdi-tools
cd /usr/src/dahdi-linux
make
make install

cd /usr/src/dahdi-tools
./configure
make menuselect
make 
make install

Now you need to do asterisk again, the patched chan_dahdi.c should still
be there. And when you get to run 'make menuselect' DAHDI channels drivers
should be there.

cd /usr/src/asterisk
./configure
make menuselect #####  dahdi channel drivers should be there  ####
make
make install

then
stop asterisk
restart dahdi
start asterisk
or just reboot the whole box
