SIP error 406 Not Acceptable, when calling from IP Office to CS1000

[nortavaya]

Hi all,

We have built a SIP Trunk between IP Office and CS1K through port 5060 TCP

On the Sig Server I can see the IPO registered correctly on the NRS, through the command 'nrsRegShow'

When checking SIP traces from IPO monitor, I got error when calling from IPO to CS1K : 'SIP/2.0 406 Not Acceptable'

On the phone I got a busy line

This the packet trace:

UDP/CDP routing already done on the NRS, but not on the Element Manager (SIP URI Mapping)

Any idea about this issue ?

Thank you

Probably not helpful, but I had to do it in Element Manager as well.

Thank you robakabobbo it resolved now, it was in the RDB SIP LD 16 you must set RBXR to NO

Only one more issue, is when calling from GR CS1K site to the IP Office we have no speech path over the phone

However from CS1K main site to the IP Office it works fine

Thank you
