If user complains that he does not hear ringing on his device when call is in progress:

1. Do NOT use IAX2 - switch to SIP

2. Configure your phone with same settings as your users and dial same number

If you can hear ringing - advice user to change its device

3. Enable sip debug and full log and look for similar message:

<--- SIP read from 193.138.191.205:64439 --->
SIP/2.0 180 Ringing
Via: SIP/2.0/UDP 82.19.82.11:5060;branch=z9hG4bK78d3ff31;rport
From: "37068111854" <sip:37068111854@82.19.82.11>;tag=as1f2d0c9d
To: <sip:281@193.138.191.205:5060>;tag=as1f2d0c9d
Contact: <sip:281@193.138.191.205:5060>
Call-ID: 03f6271f1cac11c45d6d47e67245f804@82.19.82.11
CSeq: 102 INVITE
User-Agent: X-PRO build 1082
Content-Length: 0

If such message exists that means that callee responds properly and problem is at the other end.

4. If you are dialing over some Provider to DID in MOR and get no ringing, try to change Provider. If it works - that means problems is with Provider #1.

5. Use Fake Ring as last resort
