Cisco voice router sends no Proxy Authentication

support
Level 1
Level 1

Hi,

I have a Cisco ISR 2801 with CME 8.5 and configured a SIP-Trunk to a ISP (sipgate.de).

This trunk works for inbound call, but not for outbound calls.

If I do an outgoing calls, I get the following SIP-Response from the provider:

407 Proxy Authentication Required

After this, CME does a new invite but without proxy-authentication.

for a "debug ccsip message" output, see attachment

has anyone an idea?

regards

Matthias
