Re: [Astlinux-devel] Recommendations for my architecture moving forward

Hi All

Thanks for responding.
Bria is certainly the gold standard however I have been down the Acrobits path and had a full demo of what they can provide. They have a full white labelling solution and there provisioning system is pretty cool. Just point your phone to a QR code.

David are you only opening up 5061 to the push server? If so then your iPhone must never directly register to your system externally?
Also another question; can you roam between Wi-Fi and 4G while on a call?

Regards
Michael Knill

Subject: Re: [Astlinux-devel] Recommendations for my architecture moving forward

I have had Acrobits Softphone installed on my iPhone for several years.  I don't use it a whole lot but it works well.  It has push notification for when the softphone is "in the background."  The way that works is that they have their own server that registers to your SIP port and when a call comes in their server generates a push to your iPhone and on receipt of that you open up the Softphone and somehow a handoff is done from their server to your phone.  Just recently I contacted their tech support to find out what IP addresses I should use for their servers (they have multiple) so that I didn't have to open up 5061 to everyone.  This is what I have in my custom rules...

open_for_host_port()
{
  local host="$1"
  local port="$2"
  local type="$3"
  local IFS=$'\n'
  local IPV4="$(host -t A $host)"
  local IPV6="$(host -t AAAA $host)"
  local IP=""

  for IP in $IPV4; do
    IP="${IP##* }"
    echo "[CUSTOM RULE] open port $port/$type for $host at $IP"
    ip4tables -A EXT_INPUT_CHAIN -s $IP -p $type -m $type --dport $port -j ACCEPT
  done

  for IP in $IPV6; do
    IP="${IP##* }"
    echo "[CUSTOM RULE] open port $port/$type for $host at $IP"
    ip6tables -A EXT_INPUT_CHAIN -s $IP -p $type -m $type --dport $port -j ACCEPT
  done
}
open_for_host_port "all.sipis.acrobits.cz<http://all.sipis.acrobits.cz>" "5061" "tcp"

Has anyone tested "Acrobits Groundwire" or "Acrobits Softphone" ?

It looks like many "custom" mobile UC apps are based on the Acrobits SDK.
