You would have to run two instances of Asterisk to achieve that right now. 1) You can't distinguish on source port (Asterisk will send all SIP queries from one port, I believe; the alternative is that it will pick a random port, and that is worse...) 2) You can't distinguish on destination port (your provider only has one) 3) You can't distinguish on destination IP (your provider only has one) So you're down to code modifications or running two Asterisks. Or switching provider; it sounds pretty broken to me. /Benny ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine
If your provider has two different IP addresses at its endpoint, you could use iproute2 (source based routing) with two local source addresses to make sure that there is a one-to-one mapping of source address to destination address. Then you could have two peer definitions and an address=declaration in each. As I think about it, I believe that with iproute2, you could use one provider endpoint address and two local addresses in the same manner, without the one-to-one mapping... This seems like the most elegant solution in my mind.

Re: [asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine
If that code in the below link worked, will I be able to have two SIP (IP Trunk), both send for same destination IP:Port, but from different source IP's? So the destination will authorize me in my two different IP's? Or that code will give me a chance to send from different ports to the destination? Because this does not resolve my problem as my SIP provider is asking to send for fixed IP and fixed port, the can not be changed. Any advise? Regards Bilal What are the chances that this can get eventually wrapped in the Asterisk source? If this works, I will definitely consider upgrading to 1.6 before I originally planned to.

In sip.conf setup the two remote ends on different IPs (one of which is actually bogus). Outbound NAT based on the destination, where you change the source IP to the one expected by the provider, and change the bogus destination to the real one. Inbound NAT back to the base address based on the destination in the reply. Now THAT is a hack. And it probably won't work. SIP is a known protocol which violates layer separation, encoding IP addresses directly into the application layer. Unless your firewall were able to DPI and modify the addresses within the application layer (which may or may not work, depending on whether Asterisk encodes the message with IP addresses or hostnames), then the whole exercise is doomed to fail. One way which does occur to me that will work, if the OP only needed exactly 2 different addresses, would be to set the bindaddr and tcpbindaddr to different addresses, and send TCP signalling for one peer and UDP signalling for the other. Again, this would only work for exactly 2 peers, not for more. The current code uses a separate socket for each of TCP, TLS, and UDP connections, so this would be the maximum possible without any code changes. One could probably use multiple TCP descriptors without a lot of work.

[asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine

I am confused as to what you are trying to accomplish. Can you be more specific? It seems that you are making this too complicated. You say that the remote end is providing you two SIP trunks that will come from the same IP address. To distinguish them simply have them authenticate with two different usernames. This does beg the question, though, if the endpoint is the same, why have a separate trunk? How about routing the calls based on differing CID? If you can explain the situation more distinctly perhaps an alternate method will present itself. Hard to imagine a real need for binding to multiple local IP addresses on the asterisk side. If you are REALLY stuck on doing it that way, however, how about simply running a second instance of asterisk? You would have to recompile the source to read config from a second tree, but then your second instance could bind to your aliased address.

Re: [asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine
I have the same issue, I was just asking about that. My main SIP PRI provider identifies me from my IP address, but I have two separate PRIs (different rate centers) with them. From their end I get calls to xxx.yyy.zzz.xxx and .xxy and I have no trouble getting calls, but I can only send calls from my main machine IP address so I can't control where I am sending calls to. I am hoping to have this developped somehow (a per SIP peer bindaddr and bindport), even if it means some bounty. I can't imagine this being this difficult, so a few of us who need this putting a couple hundred dollar would probably do it.

Re: [asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine
At the risk of seeming impolite (I really am not), why not? Isn't Asterisk able to send packets using another interface using bindaddr? The problem, for the two of us, is that bindaddr is Asterisk-wide, and not per-peer.

Re: [asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine
Could you not use some iptables to do this? I don't know the exact command you'd need but it could work something like... If the destination port is 5060 and destination ip is xxx then route via the default ip (so do nothing) If the destination port is 5061 and destination ip is xxx change the destination port back to 5060 and set secondary ip as the source? Just a thought... i'm guessing this would be able to do the job.. not sure what issues you might run in to by changing 5060 to 5061... but if it came to it you could try it by using an alternate ip and changing it back. Who knows... not sure if i've even read enough to understand the problem :) Cheers Geraint 2009/2/1 Mike l...@virtutel.ca At the risk of seeming impolite (I really am not), why not?

Re: [asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine
I briefly glanced at the code before responding, and it does seem that if you specify a bind address it will use that address when responding. I stick by my comment that the change you want is not exactly simple - unless you are very familiar with the 18,000 line chan_sip.c :) It also appears that the bind address is a global in this implementation... so some thought would have to go into efficiently representing all the possible peer bind addresses in a thread safe manner... and if the change is made to this channel it really out to be for all of them. So a hack is probably possible without too much trouble. For it to be done right is not a simple change.

Re: [asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine
Actually I think that is a good idea. In sip.conf setup the two remote ends on different IPs (one of which is actually bogus). Outbound NAT based on the destination, where you change the source IP to the one expected by the provider, and change the bogus destination to the real one. Inbound NAT back to the base address based on the destination in the reply. Now THAT is a hack. j On Sun, 1 Feb 2009, Geraint Lee wrote: Could you not use some iptables to do this?
