I’m a newbie testing with voip infraestructure, and i have the following problem:
I have configured an elastix 1.6 as pbx with 4 extensions:
2 extensions as softphone with zoiper. both extensions are working fine.
2 extensions with 2 Cisco IP phone 7911g with the firmware version sip. 8-3-1
I can make calls between both softphones without problems.
60267 11.850904000 192.168.10.1 192.168.10.6 SIP/SDP 910 Request: INVITE sip:firstname.lastname@example.org:60267;rinstance=6ca04e9cdffa4235;transport=UDP | 5060 274
But with the 7911g, is only possible to made call to the softphones extensions. I can’t to receive any call in the 7911g.
5060 1245.966778000 192.168.10.1 192.168.10.5 SIP/SDP 808 Request: INVITE sip:192.168.10.5 | 5060 41202
I have copied two captures form wireshark and i think that the problem is in the Request: INVITE:
With the softphone appear the extension and ring correctly, but with the hardphone doesn’t.
Thanks a lot
