Untitled Document The MX250 can connect to Internet Telephony Service Providers (ITSPs) for public SIP access to phone service. ITSPs can provide IP trunking for all business calls, eliminating the need for direct connectivity to the PSTN. At the SIP layer (application layer), ALG services translate the public IP address with private corporate addressing to allow phone calls between private IP phones within the corporate firewall to communicate with public SIP gateways. With ALG services on the MX250, a business can connect up to 50 simultaneous trunk calls through ITSPs.
