IAX2 trunk mode over satellite
Today has been the day for satellite questions, apparently, so I'll
proxy one out to the rest of the community... I asked this
tangentially a month or two ago, but I'll put it in a more blunt way:
If you have IAX2 trunking mode experience over satellite, please let
us know your experiences with that protocol/transport combination.
I've got several people asking about IAX2 and

Cisco ATA-186 config guide for Asterisk
I really should be doing something better on this beautiful weekend,
but I'm trying to save myself some time for later projects by
documenting some things that have been particularly troublesome in
the past. That being said...
I've written up a configuration guide for the Cisco ATA-186, which
describes some of the features that are possible to set in the ATA
and specifically what

sip and pix
does anyone have a sip working through a cisco pix firewall?
i can get the phone to register and the call to be negotiated, but as soon
as the call is answered there is no sound and the call ends
immediately. im sure this is due to the RTP negotiation being rejected by
the pix. any helpful ways around this? right now my only solution is to
put a small box outside the firewall and IAX the

RTP frame size location?
Google has given me too many responses, so I'll ask the list:
Where in the Asterisk rtp source code can I find the default
millisecond frame size? I've looked around for obvious pointers, but
it's not clear. I'd like to "force" my Asterisk server to use a
certain frame size all the time. (Of course, ideally I'd like to
prefer or even force that frame size in a

Asterisk internal database access

There is any simple way to have external access to the Asterisk database?
I want to be able to edit a specific family only, which is a phonebook.

stream rtp from asterisk
Hi!
Anybody familiar with streaming rtp from asterisk. Preferably with the
xorcom asterisk patch which streams rtp from asterisk to oreka audio
server. Any ideas will do just fine though!

Skype-to-Asterisk(SIP): progress
I'm sitting in the Emerging Telephony Conference, so this seems a
particularly apt place to pre-announce this...
I've wanted to be able to gateway calls between Skype and Asterisk
for a while, which of course would require some type of protocol
converter (IAX or SIP to Skype, probably.) This of course is
directly not in Skype's interest, since they would like to keep the

[IAX] Recommended soft- and hardphones?
Hello
Since SIP/RTP is a pain to use with road warriors who need to connect
from any location over the Internet, I'd like to get them some IAX
phones instead.
For those of you using this protocol instead of SIP, what would you
recommend as IAX hardphones and Windows (and ideally Mac) softphones?
Thank you.

Question on the RTP packet header
I am working on a project that uses Asterisk ARI ExternalMedia request to stream the RTP audio from Asterisk to an UDP/RTP receiver project.
Using slin16 format.
1) I believe I am seeing is a 12-byte header followed by 640 bytes of data. Is this correct?
2) Is there some place I can find a description of the 12-byte packet header fields?

Drop Call on ICMP Port Unreachable?
One of our users recently had a powerfail while connected to our meetme
gateway. (Asterisk 1.4.17 on debian 4.0)
Through the course of it, asterisk never hung up. His system came back
up, and started sending ICMP port unreachables, but the stream went on,
flooding him with "silence" media stream packets (there was nobody else in
the conference).
Is asterisk aware of ICMP

Asterisk as a GW or PBX?
Hi all,
I've got myself all confused about the capabilities of *. I somehow
convinced myself (because I see a lot emails flying around about IP phones)
that Asterisk works as a PBX and trunking gateway, but does not do voice
coding (i.e. TDM in, VoIP out). Does Asterisk work as a VoIP gateway that
regular (non-IP, non-SIP) phones can connect to and establish voice
connections to other

Forcing repacketization on SIP to SIP call
Hi folks
I have a handset talking to Asterisk, which in turn puts the call through to
an ITSP.
The handsets likes to send audio in 40ms frames (even though Asterisk
requests 20ms frames with a ptime header in the SDP).
The ITSP doesn't request any particular frame length (with ptime) or state a
maximum length (with maxptime), so when Asterisk receives the 40ms media
frames from the handset,

Experiences with Zultys 4x4 SIP phone?
Anyone had experience with this phone? The interesting features that
caught my eye were the RTP encryption, speaker "pager", and built in
4-port ethernet switch. Of course, RTP encryption doesn't exist in *
yet, but it might be interesting (I've had people ask about it, but I
don't know how serious they are about needing it.)

ISDN Primary Rate Interface (PRI) - 2B Transfer
Does * support ISDN Primary Rate Interface (PRI) - 2B Transfer Capability
for T-1/PRI?
In other words the ability to take a call and join it to another call and
then drop off letting the CO-switch take over.
