We have a FreePBX-12 / Asterisk-12 setup that supports about 24
extensions, most internal Snom870s but six or so external (Jitsi-2.8). we use TLS and SRTP everywhere on our side of the fence. The server host is a dedicated atom(tm) box using the FreePBX distro (CentOS-6.x)
and is up-to-date. Registrations require very long random passwords and registrable devices are further restricted by netblock filters. We have the usual firewall and fail2ban intrusion prevention and detection set-ups in place.
Our connection to the rest of the world is via PSTN.
We do our own DNS, both forward and reverse. We have NAPTR and…
I have a client that wants a phone system that will play sounds from a sleep machine. I tried using all different formats (GSM, WAV, WV49, MP3 etc.). Over SIP it was OK however with the PSTN it broke up from time to time. I assume this has to do with the fact that the PSTN is limited to 8khz. Is there something I am missing here or is this simply a limitation of the PSTN?
I have 2 Asterisk systems and a unique scenario where I need to play a particular tone on Asterisk1 and identify the same tone on Asterisk2. Following is my call flow, Asterisk1(Plays audiofile1,Wait for 2 Sec,Plays a tone,Plays audiofile2) -> PSTN -> 3rd Party CONFERENCE SYSTEM <- PSTN <- Asterisk2(Record audiofile1,Wait for a tone,Record audiofile2). A few points to keep in mind, (1)I can not send DTMF tones as Conference system suppresses it. (2)There is no other way to pass information from Asterisk1 to Asterisk2 (3)Asterisk2 doesn't know the length of audiofile1,audiofile2. (files are less than 200 Sec in duration)
I've got a small install with Asterisk 11. This box is connected to PSTN through a SIP trunk.
I need to add a cellular phone as a remote agent of an existing queue.
At the moment, this queue is configured according a ringall strategy and busy agent can be dialed.
My plan is : 1- to create a remote-agent context and insert a Wait statement into it so that local agents would get dialed ahead of remote agents. 2- to avoid dialing remote agents already on call (with local phones) by hanging up calls in remote-agent context when conditions are met. 3- use…
