[asterisk-users] SCCP port numbers used for audio stram?

[OCG Technical Support]

I have a 7921 wireless phone working with Asterisk, and I want to tighten
the wide open port range of my IPTABLES now.

 

I tried allowing only SCCP port (2000) in/out and found that my audio was
gone.  A quick look at my iptables message shows source port 15886 and dest
port 25968 used:

FORWARD - Drop: IN=eth1 OUT=eth2 SRC=172.31.253.4 DST=172.31.254.102 LEN=200
TOS=0x18 PREC=0xA0 TTL=63 ID=0 DF PROTO=UDP SPT=15886 DPT=25968 LEN=180

 

Can anyone tell my 

 

1.      which port range I have to open for the audio stream?

2.      Is there a way to force SCCP and the phone to use a different port
range for audio?

 

Thanks

MD
