With most VoIP problems it is best to contact Support. However, here are a few pointers:

== Problems connecting to our ~~server~~ ==

== Problems connecting to our servers ==

===Unable to register===

Line 11:

*See the [[:Category:VoIP Phones|VoIP clients page]] to see if your VoIP phone is listed and has any special notes

*Check if your router has a SIP ALG - see: [[Disable_SIP_ALG]]

== Missing calls, or strange calls ==

=== Using an ATA but the phone doesn't actually ring, but it still works ===

If you have an older phone plugged in to a VoIP-to-Analogue ATA, and if calls work, but the phone doesn't actually ring, then you may be needing a RG11-to-BT adapter that includes a ring capacitor, such as https://www.broadbandbuyer.com/products/2370-esscable-rjp-bts/

=== Ghost calls /phantom calls / Strange CLI, nobody there===

If you receive phantom calls, perhaps from a CLI (eg ~~just~~ 4 ~~digits~~) that is odd looking, and when you answer, there's no one then these are probably from portscans of your network and not actually from the A&A VoIP servers - they won't appear on the Call Log records.

If you receive phantom calls, perhaps from a CLI (eg '1001' or 'test' or '2000001' or '0700' etc) that is odd looking, and when you answer, there's no one then these are probably from portscans of your network and not actually from the A&A VoIP servers - they won't appear on the Call Log records.

These scans result in your phone ringing with a strange caller ID, but when you answer, there's no one there because it's not a real call.

**Allow Incoming SIP Messages from SIP Proxy Only [[VoIP_Phones_-_Grandstream_HT8xx#Ghost_calls?|Grandstream Phones have this option]]

* Also review your [[VoIP Security|Firewall]], and check you're only allowing VoIP traffic from the A&A servers.

==Audio/Sound problems==

Line 57:

=== Sped up or slowed down call recordings ===

This can happen when you encounter a codec issue on the machine you are listening with. We would suggest using WAV or MP3 for call recordings. This can be adjusted on the [http://control.aa.net.uk Control Panel].
