[Spce-user] Fax problem

[HFC-Network Kft - Szabó János]

Hi,

maybe you can try to enable the PCMA codec and try it again.

In 2.7 my working config.yml (I have 2.7, I don't know that it works in 
2.5 ):

sems->sbc->
     sdp_filter:
       codecs: PCMA,telephone-event
       enable: 'yes'
       mode: whitelist

Or last time I selected a slower faxing speed in a HP multi-function 
printer(with fax), and a similar problem is solved with that.

Üdvözlettel,
