Hello,

we are experiencing the following issue with Call forwarding.

We have two sites. Site A has a IPVA (its our master pbx) and a IP1060, Site B has a IP1060. Both sites have a PRI connected to the IP1060. Phones at site A and B register on the IPVA at site A.

All devices are running the newest 12r2 sr18.

Example Site A: If a user at site A sets a call forward to his mobile phone, and receives an incoming external call, the calling number will be display on his mobile correctly.

Example Site B: If a user at site B sets a call forward to his mobile phone, and receives an incoming external call, the main line number from site A will be displayed on his mobile phone. Of cause he won’t be able to call back in this case. Furthermore, forwarded internal calls will have the prefixes from site A set combined with the phones extension from site B, making it also impossible to call back.

According to the routes, incoming calls to site B are routed to the IPVA at site A and outgoing calls are routed back to the PRI at site B.

We have tried setting partial rerouting for the trunk objects without success.

Any help is appreciated!
