hi I have set Rtp.cfg to work with port range from 10000 to 20000 udp. However some Sip Trunks work and transmit rtp packages from port 32000 ± and is suppose it should work between 10000 to 20000 udp, how I can force the sip trunk to work with set ports in rtp.cfg ??? Thanks so much for any help
Did you do a “amportal restart” to restart your Asterisk PBX? Or better yet, from the Asterisk CLI>sip restart
yes I have did amportal restart, sip reload even reboot
but sip trunk is working inf port range 38k
you can see this is happening in the rtp debug know is in port 44k

This what it should look like:
; RTP Configuration
;
[general]
;
; RTP start and RTP end configure start and end addresses
;
rtpstart=10000
rtpend=20000
here my set
;
; RTP Configuration
;
[general]
;
; RTP start and RTP end configure start and end addresses
;
rtpstart=10000
rtpend=21100
the filename is rtp.conf in /etc/asterisk not rtp.cfg
yes it was a typo but the rtp is conf
rtp.conf inside etc/asterisk
and is set as bellow. and the sip trunk is not working rtp between that range
how can I force the sip trunk to work behind this rtp range ??

my provider did a trace and told me that the port 45k average is comming from my router
first router that supply internet
but i dont know how to make to work with specific range rtp port
my network is
2wire (internet and public ip, doing port forwarding to 2 router)--------------dd-wrt private ip doing port forwarding to asterisk box-------------------asterisk
rtp.conf is set 10000 to 20000
port forwarding in both routers 5004 to 5082 and 10000 to 20000 UDP
have no idea why first router is sending rtp packages inside range 35k to 45k
It could be that dd-wrt is doing NAT and PAT - PAT is port address translation which is the exact opposite of what you want. It will translate ports 10000-20000 to a different port range. Can you disable port translation? How about making a virtual server? When anything comes into the WAN IP of your router with SIP and RTP, forward it to your PiaF server.
HI. the first router is a 2wire modem. it has no option for virtual server, and i think it is no way to disable PAT.
I think the problem as you tell is that frist router 2wire is doing PAT an converting the incoming ports 10000-20000 to ports 35k up
do you think is there a option in linux that act as virtual server but then route the rtp trafic to freepbx ?
the virtual server if exist for linux should be installed in the same box as freepbx
I was wondering if other option could be make the rtp.conf from 10000 to 45000 instead of 20000 ?
or what do you suggest if there is other options to fix this ?
I modify RTP.conf to work with from 10000 udp to 45000 udp.
since the sip trunk was working in the range of 35k to 45k udp
when I did this. and execute Sip reload and amportal etc
then the sip trunk is working now in the range of 10400 as it should be I think this is very weird how could you explain that ?
