Hello,
im having trouble with the following:
[Asterisk]<------>[ISP]<------>[ADSL Modem]<------>[Linksys
Router]<------>[Grandstream ATA]<------>[Analog Phone]
On server:
- Asterisk 1.6
- A2Billing 1.4
A2Billing have 2 Trunks:
- TrExt: Voip Provider
- TrInt: Internal Calls
This structure works on first day (Asterisk+A2Billing
installation/configuration).
But on next day, i found a registration trouble in ATA:
It (ata) can not be reached by asterisk (to receive internal call), but it can
made OUTBOUND calls (via SIP Prov.)
Anyone knows if there is a NAT problem?
Following my configuration:
1 - PROBLEMATIC SIP PEER (Configured on ATA)

--------------------------------------------
Weel, from this point to ahead, the problem appears to be intermittent.
In a moment its owrking. In a couple minutes (or hours), the ATA seems to be
down (Unreacheable)
But OUTBOUND calls are always perfect.
Anyone knows something about this kind of problem?
