[OpenSIPS-Users] Processing calling-name(CNAM) from PRI

[Zahid Mehmood]

Hi Jeff,
   Thanks for your response.  From what I understand from Cisco
documentation, gateway seems to act that way when using H323 but, sadly,
not for SIP.  I will push Cisco about this.

Assuming the worst, Is there any thing I can try on the proxy side to get
the desired results?

Regards,
