[Serusers] as5400 and ser

Fri Jun 25 10:26:45 CEST 2004

If you check this page,

http://www.cisco.com/en/US/tech/tk652/tk701/technologies_configuration_guide_chapter09186a00800eadfa.html

PSTN error "63 Service or option unavailable" is
mapped to sip error "503 Service or option
unavailable" which is in the header of the message.

Also the page shows why IP phone or PSTN generates
this and how proxy is supposed to do with it. Quote,
"The SIP gateway generates this response if it is
unable to process the request due to an overload or
maintenance problem. Upon receiving this response, the
gateway initiates a graceful call disconnect and
clears the call. "

Look like a pstn config issue. Use "debug isdn q931",
"debug isdn q921" and "term mon" for further debuging.

Cheers,
Richard
