I am located in Canada and recently moved a customer from a Telco PRI to ThinkTel SIP trunks.
One issue they are having is when they call one of their suppliers and reach that company's auto-attendant and ACD queue, the call will disconnect. It is after the called side plays the "your call is important to us, please hold" message. The caller will hear a beep, and then a few seconds later, a second beep and then call disappears.
It only seems to happen to that ACD queue so far. I have called other companies and reach auto-attendants and the call stays up without an issue.
ThinkTel tech support sent this information:
"The INVITE received from the NEC-SV9100 , i can see 2 issues in the SDP headers.
1- (Minor) Connection Information (c): IN IP4 192.168.10.42 (This should be your public IP Address)
2- (Major) in your invite the DTMF RFC2833 (101 payload) is missing , how can you call to an auto-attendant , what DTMG type are you using ?"
Issue 1 - That is my IP address from 84-26. I cannot change it to the public IP
Issue 2 - I have never had to tweak any of the RFC2833 settings for other customers that are also using ThinkTel.
Anybody come across similar issues or have any ideas what to check?
