Solution 2302536.1 : ENUM PSTNSIP Service Escape Encodes “@” Sign Following Userinfo Part In URI as “%40”

Applies to:

Oracle Communications EAGLE (Software) - Version EAGLE 46.2 to EAGLE 46.5 [Release EAGLE 46.0]
Information in this document applies to any platform.

Description

The ENUM PSTNSIP (E2U+pstn:sip)service escape encodes “@” sign following the userinfo in NAPTR Response in the SIP URI as “@”.

Currently EAGLE ENUM PSTNSIP (E2U+pstn:sip) service converts and encodes TEL URL:

tel:+19897889776;npdi;rn=+d7799

As SIP:

sip:+19897889776;npdi;rn=+d7799%40info.abc.xyz.in;user=phone

(where the domain name "info.abc.xyz.in" is from ENUM profile table on EAGLE)

However the examples 4.2 and 4.4 given in RFC 4769 (PSTN Enum service) show @ sign as a delimiter between the userinfo and domain name when 'sip' URI Scheme is used.

Hence after implementing the fix (R46.5.0.0.1 and later), EAGLE ENUM PSTNSIP (E2U+pstn:sip) service will convert and encode the same TEL URL -

tel:+19897889776;npdi;rn=+d7799

As SIP:

sip:+19897889776;npdi;rn=+d7799@info.abc.xyz.in;user=phone.

Occurrence

This problem may occur if all of the following conditions are true

EAGLE is running release 46.2 software to 46.5.
EAGLE ENUM PSTNSIP (E2U+pstn:sip) service Parameter is defined and being used for response type NAPTR.

Below capture shows sample configurations.

The ENUM PSTNSIP (E2U+pstn:sip)service escape encodes @ sign following the userinfo in NAPTR Response in the SIP URI.

TEL URL:
tel:+19897889776;npdi;rn=+d7799

SIP:
sip:+19897889776;npdi;rn=+d7799%40info.abc.xyz.in;user=phone
