Re: [sipx-users] SIP trunk between Cisco Callmanager 6 and SIPXECS


Thanks,
 
I attached the wireshark capture. There is only 4 messages exchanged.You can use wordpad to open the file. After that I get a fast busy on the Cisco side.
 
Again, sipX-to-Cisco calls work but the other way does not work.
 
I could not see any domain names mentioned in the attached capture. Everything is configured based on IP on Callmanager and SIPx and the packet exchange shows that only IP addresses are used. However, SIPX server keeps sending this realm and nonce value within that 407 message and I think callmanager doesnt like that...
 
I thought it was related to the permissions so what I did is I unchecked all the permission levels for my dial peer, but this time when I call sipx from callmanager, sipx startd to send back "483 too many hops" messages. I was not sure if that was a one step forward or a complete different problem so I left my custom dial peer in "local" permission again.
 
thanks again,

Hi,

 

Create a custom dial plan. The number pattern should match the numbers used on CCM, the gateway should point to your trunk and only “Local Dialing” permission should be required.

Subject: [sipx-users] SIP trunk between Cisco Callmanager 6 and SIPXECS

 

I built a SIP trunk between a CUCM6 and SIPXECS server in our lab.
Everything in CUCM6 regarding SIP trunk is set to non-secure standard.
I can make phone calls from the phones registered to the sipxecs server to the phones registered to CUCM6 server.
However, when I try the the other way around, the sipxecs server sends a 407 Proxy authentication required message back to CUCM6 and the call fails. I only hear a fast busy signal on the phone which is registered to CUCM6.
 
On sipxecs, I set up the trunk as unmanaged gateway.
 
Any ideas on how to disable this 407 proxy authentication? Or any ideas on how to configure CUCM to respond those requests from sipxecs properly?
 
Thanks
