Change Asterisk MulticastRTP codec
Greetings everyone,
I was wondering if there was a way to change the codec that Asterisk uses when streaming via MulticastRTP. Or perhaps a way to transcode the multicast stream.
In the CLI, when I have a multicast stream in progress, I am typing 'core show channel MulticastRTP/0x7f7........' to get lots of helpful information.
I have noticed that when I do a MULTICAST page and send data

multicastRTp
I am using a cyberdata "sip paging adapter" and with the
Dial(MulticastRTP/basic/IP:port) and with
tshark I see the RTP data, my device looks like its accepting the data
and I hear a click for my relay on my device so it would seem its accepting
the call,
however - I hear no audio...
Asterisk 11.11.0 is what I am using.
What might be wrong here?
Thanks,
jerry

Multicast RTP
I'm currently working with Asterisk 11.8.1 trying to get Multicast RTP
working (it's not) with some Polycom phones, and I'm really trying to
determine if Asterisk or the phones are the issue. I THINK it's Asterisk...
In extensions.conf I have a simple: "Page(MulticastRTP/basic/x.x.x.x:xxxx)
line, and when I dial that extension I get:

Multicast to polycom from asterisk
I am using 11.17.0 - and MulticastRTP. Doesnt seem to work with
polycom phones as other devices receive my multicast just fine.
Is there something special to do to get multicast working with polycom
phones?
(other than enable multicast on the actual phone).
Thanks

multicastRTP source interface
I have an asterisk 11.4.0 server with two interfaces, eth0 and eth1.
Eth0 has a default gateway on it, eth1 is connected the subnet that has my
phones registered.
I'd like to use the multicastRTP driver to do paging. However, when a
phone dials an extension with multicastRTP, the multicast stream goes to
the primary interface (eth0) and it really needs to go to eth1.

How to defer SDP in ACK for unit testing purposes
Hello,
I think I met a case similar to the one solved by [1] . Quoting this case :
* res_pjsip: Handle deferred SDP hold/unhold properly.
Some SIP devices indicate hold/unhold using deferred SDP reinvites. In
other words, they provide no SDP in the reinvite.
A typical transaction that starts hold might look something like this:
* Device sends reinvite with no SDP
* Asterisk

Asterisk translates 200 OK + SDP into 488 not acceptable here after both side agreed on codec.
Hi List
Asterisk 16.28.0 in use.
PJSIP in use
Two endpoints
Both using IPv6
One Endpoint on UDP, the other via TLS.
Both with:
t38_udptl=yes
;fax_detect=yes
;fax_detect_timeout=30
rtp_ipv6=yes
Both sides are T.38 capable and detect fax tone so no need for fax
detection on asterisk.
Voice calls between the two work fine.
But on a Fax call, I see this situation:

Send 200 OK with SDP instead of 183 with SDP when ringing starts
Hello, all. I have an asterisk 2.3.2 and a Sangoma interface through
which I connected an external PSTN line. I use it as carrier for VoIP
calls. I can make successfully calls, but there's one problem, I receive
200 OK with SDP with delay (sometimes more than 30 seconds).
So when I make a call through asterisk I receive intially:
- 100 Trying
- 183 Session Progress, with SDP

180 Ringing with SDP
We're dialing a disconnected number via Level 3's vector network, and
are receiving this. The response has SDP in it. Apparently, Level 3 is
playing early media. Asterisk doesn't seem to know what to do with SDP
in a 180 RINGING, and just plays ringing. What am I missing here? How
can Asterisk see there's SDP, early media, in the response and act
accordingly?

SPA504G auto answer
Hello,
I am struggling to have a SPA504G to auto answer (for intercom/paging). I
have tried the following SIP headers (not all together), but without luck:

SIPAddHeader(Alert-Info: info=intercom);
SIPAddHeader(Alert-Info: Ring Answer);
SIPAddHeader(P-Auto-Answer: normal);
Any other ideas?

Asterisk behind NAT and Kamailio --> Internal IP in SDP and not "externip"
Hi,
We have some Asterisk servers that we are moving behind a NAT to
preserve public addresses and make room for growth. This is Asterisk 1.4
NAT works very good with the externip/localnet-setting when we are
connected directly to our teleco. But when I try to use NAT and put them
behind our Kamailio something interesting happens: The media-address in
the SDP is the internal ip and not the

No change in payload. (SDP)
re-posting the question.
-----------
use case:
when some one in my pbx calls 100.200, I have translations well defined, Media also (media via asterisk) --Works.
when some one calls bob, or for any names I am adding Domain and call is been sent to the other party -- Works, no media...
For the cases when it is talking to the external work,
I want Astersik not to do anything with the SDP/payload.

How to stop Asterisk from changing the SDP?
I'm trying to set up a direct SIP connection and have Asterisk stay
out of the media stream. When I look at the INVITE messages, I see
that Asterisk is changing the Session Description Protocol in the
INVITE message it receives, and send a INVITE message with a different
SDP to the receiver. This is not what I want. Is there any way to make
Asterisk leave the SDP exactly like it is sent from

SDP messages relating to rtpmap Question
SDP question if * recieves "a=rtpmap:103 telephone-event/8000" it shouldn't
it send out the same "a=rtpmap:103 telephone-event/8000" to the other side
of the connection? and not something like "a=rtpmap:101

Is this SDP payload Asterisk created valid?
We have an issue with a customer where when calls are sent to one of their offices as soon as the call is answered the call fails.
We are performing remote bridging and switching the audio from the server which initiated the call to our switch which is on the same network.
After the call is answered we switch the audio which is accepted fine but we then send the following packet and get a SIP/488

no ring back 180 with SDP
I have a box (Genband) expecting the following:
100 trying
180 ringing with SDP
Or
100 trying
183 with SDP
And asterisk is sending:
100 trying
180 ringing
183 with SDP
Any way to modify asterisk to send what he is expecting?
Thanks,

no sdp or contact replacement using externip
Hi all! Do anybody has a full working environment using externip on an asterisk box behind a nat? I tried with two diferent boxes (Elastix-1.4.24 e Trixbox-1.4.22-3)and the asterisk do not replace neither contact, neither sdp headers info with the externip informed on sip.conf general parameters.
I used these two statements:

Asterisk put call on hold when receive 183 Session Progress with media address 0.0.0.0 in SDP
Hi
Is it a normal behavior of Asterisk put a call on hold when receive a
Session Progress with media address 0.0.0.0 in SDP? I believe the call on
hold should be initiate with a re-invite.
Thanks
