Summary:                    chan_multicast_rtp.so    MulticastRTP no audio when
using Page()  App
Description: 
When I use the Page() app with the MulticastRTP channel the phone answers
but i don't get any audio. when I use the Dial() command the audio works
fine. 
the Page() command works fine with the SIP channel. just not the
MulticastRTP channel. let me know what i can do to help debug this issue.
Thanks,

---------------------------------------------------------------------- 
my sip.conf is defaults other than:

udpbindaddr=:: 

(and the phone config)

[4005]
context=default
type=friend
secret=4005
callerid="test" <4005>
host=dynamic                    
;nat=yes                         
;directmedia=no                  
disallow=all
;allow=gsm                      
allow=alaw


 extensions.conf:

[page]
 (not working)
exten => 4000,1,Answer
exten => 4000,n,Set(CALLERID(name)={Page:${CALLERID(name) })
exten => 4000,n,Set(TIMEOUT(digit)=5)
exten => 4000,n,SIPAddHeader(Call-Info: Answer-After=0)  ;  Grandstream,
Snoms
exten => 4000,n,SIPAddHeader(Alert-Info: info=alert-autoanswer)
;AASTRA/poly
exten => 4000,n,Page(MulticastRTP/basic/224.0.1.200:9999)
exten => 4000,n,Hangup

(works)
exten => 4200,1,Answer
exten => 4200,n,Set(CALLERID(name)={Page:${CALLERID(name) })
exten => 4200,n,Set(TIMEOUT(digit)=5)
exten => 4200,n,SIPAddHeader(Call-Info: Answer-After=0)  ;  Grandstream,
Snoms
exten => 4200,n,SIPAddHeader(Alert-Info: info=alert-autoanswer)
;AASTRA/poly
exten => 4200,n,Page(SIP/4005)
exten => 4200,n,Hangup

(works)
exten => 4300,1,Dial(MulticastRTP/basic/224.0.1.200:9999)
exten => 4300,n,Hangup


also take a look at the pcap files, in the file mrtp-dial-cmd.pcap you
will see data in the data field for the 224.0.1.200 multicast address. but
in the file mrtp-page-cmd.pcap using the page command the data filed is all
ff's


Thanks, for your help.
