OS7000 interconnection SIP Server HUAWEI - RX/TX fax in T.38

[Felipe Caroca]

Systems testing:

SIP Server - HUAWEI: internal (LAN) and external (Internet)

OS7400 - MP40=4.14k, LP40=1.17, MGI16=1.20 and licenses for SIP Stack

OS7200 - MCP=4.14k, MGI16=1.20 and licenses for SIP Stack

I have problem with two provider NGN services (softswitch) in testing for send and receive fax over IP with standard T.38

Additional information, send and receive fax over IP with codecs G.711a not problem, but provider need forced all softswitch for operate prefer G.711a

Almost provider first standard for fax over IP prefer is T.38, others brands not problem with standard

Does anyone have more such problems?

Does any immediate solution?

Dear Felipe!
SIP and T38 operation depend on ITSP settings and environment...
So.. I will try to invite to visit this place the Samsung SIP stack developer Mr. Sung Woo Lee
Please hold on here.
If he will not come to this forum then please excuse me..
In this case I'm strongly recommend you to contact with your Samsung systems dealer to solve this point via official ways.
