Sometimes, when we need change somethings in AudioCodes, we can receive the follow message:
!! [ERROR] #0:TrunkGroup::AllocateEndPoint- Can’t find EndPoint for phone number 1052
!! [ERROR] MotherBoard::GetEndPoint- Can’t find EndPoint for Dest:1052 Source:+7503 SourceIp:a000098
!! [ERROR] Call::GetEndPoint- Can’t find endpoint for phone number 1052
?? [WARNING] Call::PassEvToOtherSide m_EndPoint is NULL!!
So, an interesting thing, is that AudioCodes have differents kinds of routing table.
In the picture below, we can see an incoming call, this way is called TelToIP.
From PSTN(E1/T1) to AudioCodes
AudioCodes to Skype Pool
If this is your case, check Tel to Ip Routing and make sure that your regular expression match with one of the rules.
But if your case is reverse, check the Ip to Trunk Group. Trunk Group is the given name to a trunk with E1, T1,Euro ISDN or something like that.
I hope this little article help you to understand the call flow.
