CUCM 9 - Connect multiple SIP-Lines from same IP

[b.ruehl_MCP]

Dear colleagues,

on our CUCM 9 i created several third-party-sip-devices. We have some SIP-Clients that should connect to the CUCM.

Connecting one SIP-Account works just fine, but if i try to connect a second SIP-Account from the same softphone i always get a 404 - not found error. If i disable the first line, the second line just connects fine. Is there any way to connect multiple sip-lines from the same IP?

Are there any settings to be made? is this a known bug?

Thanks for your advice!

Best Regards!

Berthold

Hi Berthold,

Refer the following doc:

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/10_0_1/ccmcfg/CUCM_BK_C95ABA82_00_admin-guide-100/CUCM_BK_C95ABA82_00_admin-guide-100_appendix_01101101.html#CUCM_TK_T0F65957_00

Cisco Unified Communications Manager does not support third party SIP phone registration using the same IP unless the combination of the IP address and the port number in the contact header are unique.
