[SIPForum-discussion] SIP Error 481

Wed Sep 19 08:33:01 UTC 2012

Hi Team,

We have a network set-up of SIP Peering services, with details below:

ASTERISK PBX - SESSION BORDER CONTROLLER (PROXY) - HUAWEI SOFTSWITCH (PSTN GATEWAY)
[cid:image001.jpg at 01CD9684.6F8E0400]

Calls originating from the PSTN Gateway is able to establish connection to Asterisk PBX but the call gets cut after 5 minutes. We experience Error 481 from (SBC - 10.249.211.20) to (Asterisk - 10.251.3.153).

Expert advice please on how to resolve this.

Thank you very much.
