Hi again, list! I know, I'm really annoying the list... :) Well, maybe I got my Asterisk at home ("wrt" on the previous E-Mails) to accept my mobile phone from Internet. It was a problem with the network and the firewall. Now I can log my mobile phone in my Asterisk in and the phone is REACHABLE. Wow! Got it! If I call a phone at home using my cellphone it works and the

For such cases i created a dialplan in the default dialplan which blocks the ip of the hacker with iptables.

I'm guessing this is a small/home system? I suggest you install SecAst from this site: www.telium.ca It's free for small office / home office and will deal with these types of attacks and more. It can also block users based on their Geographic location (based on the phone number it attempted to dial I suspect this is middle east), look for suspicious dialing patterns, etc. If you

Hi list! Very strange... I ran the Asterisk CLI for other tasks, and suddenly I got this message: == Using SIP RTP CoS mark 5 -- Executing [000972592603325 at default:1] Verbose("SIP/192.168.20.120-0000002a", "2,PROXY Call from 0123456 to 000972592603325") in new stack == PROXY Call from 0123456 to 000972592603325 -- Executing [000972592603325 at default:2]

Hi again! I decided, "just for fun", to install Asterisk on a server of mine (available in Internet) and to log on my mobile phone on this server. This Server communicate with my Asterisk at home and if I call a phone at home from my mobile phone (logged on the Asterisk on the second server), it work perfectly with a very good audio quality. If I log my mobile phone (and just tried

Hi list! Since the internal calls work as expected and I can register my Asterisk on an external provider, I'd like to add a new feature and allow my mobile phone to connect to my Asterisk and manage calls. Well, first of all, my Asterisk is NOT direct on Internet available, but behind a NAT. So I configured my sip.conf: localnet=192.168.200.0/24 externhost=myhost.noip.com externrefresh=180

Have you tried NAT=force_rport ?

Hi All, I've looked through the archives and tried several variations in Google, and I haven't found anything on-point... So I'm hoping someone here may be able to help this relative Asterisk neophyte shed some light on an issue: I have a box running Asterisk 1.4.22 in our lab with several Cisco 7961G phones and an AEX804E card (4 FXO, hardware echo cancellation). The server and all

Hello list, I am confronted with the following problem : making a call only leasts for about 30 seconds, then the call is ended. The CLI shows : [May 21 14:31:50] WARNING[25345]: chan_sip.c:1980 retrans_pkt: Maximum retries exceeded on transmission 954539948-5060-2 at 192.168.1.100 for seqno 11 (Critical Response) -- See doc/sip-retransmit.txt.

Hello All, Got one customer and he is getting disconnection within 15 seconds when he tries to make outbound calls. Initially, it was working fine without any glitches... Other customers on the same system are working fine, its just with this customer only. This is the error message thrown by Asterisk on the CLI: - Jan 18 12:23:30 WARNING[30532]: chan_sip.c:1228 retrans_pkt: Maximum retries

Hello My asterisk is receiving calls from OpenSER but all calls hangup in 20 seconds. This only happens because Im using Asterisk2Billing's AGI (without A2Billing it doesnt hang up). does someone knows whats the problem?? Here is my Asterisk debug: (xxx.xxx.xxx.xxx -> the phone's IP) Apr 10 02:03:02 WARNING[6996]: res_musiconhold.c:508 monmp3thread: Unable to spawn mp3player Apr

Hi, I?ve installed Asterisk for use as a SIP server. I can call people, but one strange thing happens: if I call someone with a SIP account outside my server (for example, sip:enum-echo-test at sip.nemox.net) everything is fine, if I call any Asterisk extension it also works, but the call gets disconnected in about 20 seconds. To be exact, audio is turned off but the SIP client still thinks

This seems basic but something is missing..... I dial from my cell phone to my DID and enter the context in extensions.conf I am hoping to cascade through the plan and successfully automatically dial the 1444 number listed. But it fails. And, I dpon't know why? Should I removed the Hangup application? Syntax issue somewhere? I have a good SIP registration with the vendor, voipvoip.

Hi All, A long time ago I posted about an issue where calls on one of our Asterisk boxes were being dropped in Voicemail (and only in voicemail) after about 20 seconds with the error logged "[Jan 19 14:33:26] WARNING[27458]: chan_sip.c:1980 retrans_pkt: Hanging up call 001d45b6-1d490088-46ef7ed6-adbeb875 at 10.2.0.203 - no reply to our critical packet (see doc/sip-retransmit.txt).".

Hi there I am wondering if anybody can help me illuminate a problem I am having with my asterisk installation. I am using: - IP phone (Siemens gigaset S685IP) behind a modem/router that has ports udp 5060 and 10000:10100 forwarded to the static ip of the IP phone (192.168.0.3). This has to go to: - modem that operates in half bridge mode (no nat) to a linux firewall (does natting ip is

I have found a very strange problem. We found that the time of establishing the websocket connection between mobile phone and server was too long. Then I use tcpdump to capture the data and found that the problem maybe has something to do with window scale option in SYN packet. Here is the SYN packet for websocket connection: 55488 ? 443 [SYN] Seq=0 Win=65535 Len=0 MSS=1460 WS=64
