This is odd the telco is sending in the calling party number minus the leading 0;
Nov 13 14:25:57.378: ISDN Se0/0/0:15 Q931: RX <- SETUP pd = 8 callref = 0x0002
Sending Complete
Bearer Capability i = 0x9090A3
Standard = CCITT
Transfer Capability = 3.1kHz Audio
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA98382
Exclusive, Channel 2
Calling Party Number i = 0x2183, 'XXXXXXXXXX'
Plan:ISDN, Type:National
Called Party Number i = 0x81, 'XXXXXX'
Plan:ISDN, Type:Unknown
The Cisco handset show 'Unknown Number' on the screen.
I have tried adding the 0 under 'Service Parameters' => 'Advanced' for the the h323 Gateway settings but realise that this will cause issues on my other 5 x h323 gateways that all work fine.
When I trace the call in RTMT is see the 0 prefixed to the incoming number but the Cisco Phone still shows 'Number Unknown'.
Do I need the Telco to send all 11 digits which of course includes the leading 0?
