Hello,
I have some challenges with a VPN setup for voice traffic I recently configured for a client.
I have at the HO (Head Office) the following:
- 1800 router
- Avaya phones and Gateway
- 1MB radio internet access
At the BO (Branch Office), I have:
- 871 Router
- Avaya phones
- 256k internet bandwidth
The only reason we setup the VPN was setup was to enable the phones at the BO to connect to the gateway at the HO while also being able to make and recieve calls at the BO.
The phones at the BO successfully register to the HO, but are unable to recieve calls and dial out. Everytime I try to make a call, the phone displays a "connecting..." message.
Please see the attached config files.
Could it be the bandwidth of the VPN tunnel because when i checked sh int tunnel, i got the message below:
