If you are going to use an external SIP carrier to group referrals, configuring your firewall is an important step to properly customizing the Elements platform. Clients using Cookware (gateways or voip) sending traffic directly to a network endpoint (Cisco Site Call Manager or PBX) generally do not need to reconfigure their firewalls.
In order for Voice Elements to successfully communicate with your operator,SIP rum to allow site traffic is required to control calls over the Internet and the audio part to allow any type of call control.
The call is usually sent on port 5060 and UDP. Messages sent to this port, of course, consist of SIP-ons (RFC 3261 messages) that start new definitions and terminate existing connections.
SIP Sniffer Warning
These bots are looking for SIP servers connected to the Internet, trying to hack them, hoping to find vulnerabilities, most of which will allow them to make absolutely free calls to your system. fight
In addition, we HIGHLY recommend that only IP addresses from SIP trunks be allowed access to this port. Most
Firewall rules specify which IP contacts can send traffic to the public, using this feature, which is most often associated with a firewall, will greatly increase personal security.
Network operators usually publish the IP addresses from which such people send traffic, send you emails, or call support formore information.

In addition to
Open SIP 5060 port opening for signaling, ports must also be open processing for your current audio. Audio is transmitted over the UDP protocol. By default, Elements voice uses port 49152 as its starting point. ports The number depends on the number of concurrent calls that you handle at the same time as your server. In addition, each emergency call requires two neighboring ports.
If users plan to have a system with a thousand “simultaneous calls” 1000 and “licensed ports”, users will only need 2 possibilities for the port number you need in your firewall or is sufficient. This can be a little confusing because it only takes one worker to make a call, but “port” requires two “IP ports on your server”.
To complicate the calculations, it is possible that one orseveral ports that you need in your port range are already in use by the management system. In case this Tone elements Voice ignores the actual ports and fixtures used. The upper bound for ports exceeding 250 is also the upper bound.
In short, the correct number of vents to open on your firewall is following this excellent formula:
For RTP/audio: open ranges from 49152 (udp) to (2*number of concurrent licenses) or 250+.My
1) Ping the PC near the device.

Note. Typically, these ports do not have to be connected to the source IP addresses of the SIP operator, since many racks use different ones for the audio ip address. Therefore, we generally recommend, unless you specify otherwise, to open these ports of each for an IP address.
