Calls hangup in 2 sec

Hello TEAM
Recently we are experiencing a recursive issues … calls are being cut in 2 sec…

while checking the connectivity found next behavior,

Strict RTP learning complete - Locking on source address { INTELLIQUENT IP }

IP 216.x.x.x which we don’t recognize …any thoughs?

hello fellow according to your issue i am suggesting following steps may be it will be helpful for you:

1: Check your firewall and NAT settings to ensure proper traffic allowance.
2: Review SIP provider configurations and logs for errors.
3: If issues persist, contact INTELLIQUENT support and consider updating Asterisk.

may be your sip is not supported for this and also update asterisk to latest version

Contacted Voice provider… they have requested to have wider range for RTP … currently testing.

thanks for your support and comments.

Weird. By default, Asterisk uses ports 10000-20000 on its end and will accept any port at the remote end. How much wider could they want?

They indicated a wider scope almost double 50000 …
checking traffic connections…

Cisco (and other well behaved services) use

16384 - 32767

As a side note, any range that starts and ends on an even number is technically possibly problematic (including 10000-20000 )

Issues have decreased with this last adjust… although there are a few disconnections yet!.

Have you confirmed you have your carrier’s required CODECs enabled?

Hello … Yes… Codec was the same… but it seems a wider range was finally needed… issues decreased notably these days.
