Hello to all,
I have wierd problem at the customer. he has trunk to local provider with three channels (three simultaneous calls).
And sometimes happend that incomming call-stream (RX) is being choppy really hard. Doesn’t matter if customer calls or someone calls to customer.
I cought the tcpdum on FreePBX once and there I can see that incomming RTP pakets has really huge delay. So I naturally blame the provider, but he told that it’s all just fine on his side.
This provider also offer redirection service, so when problem mentioned above occurs, customer set this redirection to GSM GW, so all incomming calls to that provider’s trunk are being redirected to GSM on provider’s site and everything works fine.
But when customer set this redirection off after few days, trunk works two or three days OK and after that being started choppy again and still in that one way.
Has anyone had similar experience?
Any idea why this is happenning?
