If you want to practice making a call and check that your communications
infrastructure was properly configured with your Twilio Trunk, you can make a
test call to our friendly assistant Play. She will prompt you to record a
message, and then play it back for you - you will know right away if your
configuration is working.
Below, you will find the phone numbers you can use to reach Play and test your
Elastic SIP Trunk. These numbers may only be called via your Twilio Trunk and
are free of charge.
+1(650)4-TWILIO (+1(650)489-4546)+1(415)475-TEST (+1(415)475-8378)+44-1-61-850-TEST (+44-1-61-850-8378)+55-1-940-42-22-55If your call didn't go through successfully, heard no ringing tone and/or simply got disconnected you probably have a problem with the number format you are using; please check that you're using standard E.164 format. Or you may have a problem with your Authentication settings (see Termination settings) or your communications infrastructure configuration (see Configuration Guides). It is advisable to look at your communications infrastructure logs and/or PCAP which may indicate how the call failed.
If you heard a ringing tone but didn't hear Play's voice, you probably have an IP addressing issue for the media ranges. Please make sure you're using your public IP addresses in your SIP/SDP and re-check your Firewall settings (see IP addresses).
If you heard Play's voice but didn't hear your own recorded message played back, you probably have a problem with your Firewall settings (see IP addresses) or your communications infrastructure configuration (see Configuration Guides).
If you heard Play's voice and heard your recorded message, then your configuration is working just fine and you're good to go!
If you are still encountering issues, check out our Troubleshooting your Trunk page, where you can find some common issues you might encounter when configuring your Elastic SIP Trunk.

For Caller Name Lookup setup please (CNAM).
Once you have saved changes to your Trunk in your Twilio Console, you should test Caller Name Lookups using a PBX enabled phone line.
To test this feature, first ensure that your phone line is connected to a Trunk where Caller Name Lookups are enabled.
Using an outside phone line that is connected to the PSTN (such as a personal cell-phone) place a call to the phone line, and you should expect to see your name in the 'From' or "P-Asserted Identity" header of the SIP INVITE for the incoming call.
Finally, check your Twilio Console Call log (Elastic SIP Trunking > Logs) and confirm to see that the Caller Name appears along with the telephone number in the 'From' column.
Note that Caller Name lookups for US/CAN numbers are billed per lookup, even if data may not be available. Currently, requesting Caller Name Lookup for international numbers will return null values, but will not be billed.
