RTP/NAT Traffic to private IP
Hi all,
I'd like to connect a softphone at home (nat, dynamic-ip) to a sip-phone
in the office via asterisk 1.4.21 (nat, fixed-ip). SIP works well, the
phone is ringing, but when I pickup the call, there's no audio on both
sides.
I debugged the rtp-traffic at home. As long as the phone is ringing,
everything is fine. But after the pickup, asterisk sends a SIP/SDP
package with its

SIP vs RTP destination IP
Is it possible to have asterisk override the connection information embedded
in a SIP 200 packet with the registration information? I have multihomed
machines with softphones and they register just fine and sip works fine, but
the RTP packets get sent to the ip from the SIP connection information and
the softphones are sending the wrong ip. I can't find an option in the
softphone to change ip

How to configure asterisk to only accept SIP from kamailio@localhost but exchange RTP on all interfaces?
I have a setup with asterisk-11.7.0 and kamailio-4.1.1. I am following the setup guide at http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb . I want to run asterisk and kamailio on the same server, with SIP realtime configuration
(MySQL database) so that kamailio authenticates and then forwards the registration to asterisk on localhost. The setup calls for asterisk to be

RTP stream when * and Xlite are both behind Nat devices.
Hi,
I have an Asterisk box behind a NAT address and also a Xlite 4 soft phone
behind a different NAT network.
Asterisk -> Nat -> Internet -> Nat -> Softphone.
I can register my softphone to the asterisk box ok via SIP but the RTP
stream from the asterisk box is addressed to the private non-routeable
address of the softphone when I turn on rtp debuging.
How can I configure the rtp

rtp problem with 1.8.0-rdc1
Hi. I am having a very strange problem --aren't they all -- with the

softphone, all rtp traffic ceases! Now, a version which does work is

RTP codec 13 received - Cisco incompatibilit y?
I have a similar setup to you and get the same message regularly. I don't
think it's the cause of your problem. I did some research on it a while ago:
IIRC the cisco uses codec 13 for "silence suppression" whereas asterisk
(correctly) uses codec 19. The router can be configured to use 19 also, but
I didn't bother. I'm sure somebody will correct me if I'm wrong about

RTP codec 13 received - Cisco incompatibility?
Hello,
In our SIP network, Asterisk is the central PBX, and it routes calls to the
PSTN thru a Cisco Router - IOS 12.2(11)T9.
If a client softphone calls directly via Cisco to the PSTN, the call works
successfully.
If the client softphone calls via Asterisk to other SIP internal extension,
it work fine too.
The problem is when a client calls an Asterisk extension, and Asterisk
transfers

Asterisk is on public IP (as described in the first email)
i have 10 years experience in voip, 4 years webrtc in production. i know
about ICE/STUN/DTLS-SRTP. yes, not every detail but the basic mechanism
but i confess. i dont understand WHY Asterisk SOMETIMES switches
destination IP in RTP. this is not only about ICE. its about RTP engine
too which is Asterisk specific

Softphone RTP Session Start-up Delay
Hello,
I have a small LAN network where I am running a Jain-Sip softphone on two user pc's. These softphones are connected through Asterisk(Trixbox). Although the phones do work in providing an audio conversation, there is a long delay(about 20 seconds) in the initial RTP session setup. I have tried a few values for the buffer length including setting it to zero. I assumed this would

I need your advise please.
I am trying to establish a call from Asterisk 1.8.15-cert5 to one remote SIP

nat=yes in my sip.conf but yet RTP packets are being sent to its internal IP

It's probably best if you read the logic[1]. There's an entire comment that
talks about how it works.
