Hey All
Yeastar s300 (Asterisk) operates in dual port mode (WAN for communicate with other PBX via SIP Trunks, and LAN isolated for Phones connect only). The SIP Trunk is up. An interesting situation is observed. A call from phone A (connected to s300 DN444 site prefix 420) to phone B (connected to CUCM14 SU1 DN1001 site prefix 40) goes through normally. A call from phone B (CUCM) to phone A (s300) also goes well, but after phone A hangs up, the user of phone B hears the message from CUCM: The dialed number cannot be connected, check the number and retry the call
RTMT - (1) Unallocated(unassigned) number. Explanation: The number requested by the calling user cannot be reached be cause it is not currently assigned to any user by the network
Logs for this call attached
