[SIPForum-discussion] Problem with Call Forwarding of SIP phone toa PSTN Phone

I am new to SIP but have extensive background in PSTN voice network.   What you are trying to do is not allowed as the Caller B is forwarding his/her number to an International operator-Assisted destination which needs operator intervention to enter Calling or Credit Cards information for billing purpose.  01+ is defined as International operator- assisted call and 011+ is an International direct dial (DD).  Hope this help.  Thanks

Hello everybody. 
I've been working with a pilot test with the following conditions: 

1. In the LAN i have two SIP phones, which register to a IP PBX. 
2. The customer wants to have a call forwarding with the conditions that i attach in the PPT file. 
3. When i try to make the call forwarding, i get an error from the Gateway ( Cisco 2801). I attach the debug. 

Any comments will be appreciated.
