I'm working with call park. If I place an internal call (phone to phone) , I can park the call and pickup it up on another phone by dialing the call park DN. If I place a call from PSTN into HQ via the 6608 , I can park the call and pickup it up on another phone by dialing the call park DN. If I place a call from PSTN into HQ via the br1-rtr (MGCP) , I can park the call but get a message that "your call can not be completed" when I dial the call park DN.
Any ideas?
