Problem calling out....

[BlueDream]

When I place a call and that call is answered I hear the person speaking for about a second and then it cuts out..... The person on the other end can hear me talking fine...?

I hear the dial tone fine, and like I said just above, I get a very brief period where I can hear the person who answered.

I receive calls fine, full duplex - I guess you'd say

It happens for all types of outbound calls, ENUM and calls routed through a VSP.

Any suggestions on where I should start looking..?

I'm not positive but I'm nearly sure that I haven't messed around with any of my settings as it was working fine before.....

Also another thing is that in my VSP list I have specified a VSP which I dont want to register to (so have set the SIP registration status to 'NO'), as I only use this VSP to place calls and not receive them but the status of it always says it is registered, is it supposed to be like this?

Thanks.
