Re: [asterisk-users] sip register peer (the quest for near 100% availability)
If you have no NAT or dynamic IP in your network, you can just remove the registration process and assign to each peer its IP address. This is the answer. If 100% availability is critical, your IP addresses shouldn't be changing anyway, so take the registration process out entirely. This advice is not valid for android / iphones though. You need the register to be able to have good battery life on those. If you use TCP, the softphone will go to sleep, OS will keep the stream alive. When a SIP packet comes in (INVITE, OPTIONS etc), the OS will wake up the softphone and the softphone will handle the packet. No register means no stream and the softphone will just sleep forever.

Re: [asterisk-users] sip register peer (the quest for near 100% availability)
Hello. I am aware that 'sip show peers' will display my peers, and that 'sip unregister ' (where is the peer name) will unregister a peer - however, I want to force registration of a peer from the CLI. Is there any way to force this? I have several user agents and I want to achieve near 100% availability for all peers. I realise that the peer will be 'woken' up at my qualify intervals, but can I actually force registration from the CLI? A REGISTER request originates from the peer. How do you propose Asterisk ask the unregistered peers to REGISTER in a device agnostic fashion? Maybe it's possible to send a NOTIFY to a peer on the last IP it was seen at? I don't think I've seen anything that has a register command, but lots of devices can get a check your config or reboot command via SIP NOTIFY. I'm more wondering why the peer is unregistered but we still expect to communicate with it. Other than a network problem or the device being unplugged...neither of which could be fixed from the server. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

I have a feeling that some people in this discussion have a lack of understanding about the SIP protocol and the underlying networking that could affect it. The original post failed to say whether this was on a LAN without routing, on a LAN with routing, or a WAN. Each of those could result in totally different results and solutions. -- Carlos Alvarez TelEvolve 602-889-3003 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] sip register peer (the quest for near 100% availability)
Another option would be a VPN between the phone and the LAN the Asterisk box is on. VPN software may handle IP address changes better than the Softphone. This way the IP of the softphone doesn't change. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of joachim Sent: Thursday, January 31, 2013 11:14 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] sip register peer (the quest for near 100% availability) This is the answer.

Re: [asterisk-users] sip register peer (the quest for near 100% availability)
Is there any way to force this? I have several user agents and I want to achieve near 100% availability for all peers. I realise that the peer will be 'woken' up at my qualify intervals, but can I actually force registration from the CLI? For those peers which are at known, fixed, predictable IP addresses (e.g. in-house phones which have statically-configured IP addresses or which get non-dynamic addresses from a DHCP server you control) you do not need to use registration at all. You can simply hard-code the peer's address into sip.conf (or, I presume, an equivalent realtime table). When you Dial() such a peer, Asterisk will start sending out the INVITE packets, regardless of whether it has heard anything at all from that peer in the last hour or fifty. No need for qualify although you can use this to keep track of whether the peers are actually alive or not. If you take this approach, you'll save yourself a great deal of heartburn if you can figure out an automated way of keeping the IP addresses synchronized, between Asterisk and whatever hand out the addresses mechanism the phones use (DHCP, TFTP-based provisioning files, etc.). Keep a master list of peers and addresses in a simple table or file somewhere, and use this to populate the other pieces of software which need to know. For peers which can move around to arbitrary IP addresses, and where your server system won't know what those addresses may be in advance, using REGISTER from the device is really the only good approach. If you've got a setup where devices change their IP address frequently and need to be on-line constantly, I'd say you have a fundamental problem with no easy solution. Using a short registration time limit (e.g. 30 seconds) is probably the least awful way to handle this, and if you're talking about a very large number of phones you may want to set up a dedicated SIP proxy to handle this registration burden and keep Asterisk from having to deal with it. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

You can just shorten the time the phone device register on the asterisk server. It is up to the peer to send the registration command. It cannot be triggered or forced in any way.
