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.

Yes...I'm a noob to both Asterisk and Linux. We used AsteriskNow for the
install and, if I am interpreting the below correctly, I don't have the
source files needed. How do I apply the patch?

Perhaps you used the wrong -p or --strip option?
