SIP Registration forward for contact remapping, 401/407 pass through challenges for SBC, and tone & early media handling

Hello,

I have some questions which are given below:

1- SIP registration forward – contact remapping: It seems I can only register once per username + domain; eg 0123456@domain. Although I can register the second SIP device via the same user however the second SIP device cannot make a call and the call gets rejected. How I can adjust the limit?

2- SIP registration forward – 401/407 challenge: Will SBC pass through 401/407 challenges that PBX asks for terminating outgoing calls?

3- Tone and 183 handlings: I could not find any specific document that explains tone and early media handling under the Profiles. Can you please point me in the right direction?

Thanks

>> You can only register one user with the same username and domain. We already have internal tracking for this problem. Trk#23621 and our developers will work on it.

2- SIP registration forward – 401/407 challenge: Will SBC pass through 401/407 challenges that PBX asks for terminating outgoing calls?

>> Yes it will pass.

3- Tone and 183 handlings: I could not find any specific document that explains tone and early media handling under the Profiles. Can you please point me in the right direction?
