[Freeswitch-users] Set an gateway parameter for external gateway (skype)

[Peter P GMX]

Hello,

I have a main freeswitch server and a separate Freeswitch/Skype server
with mod_skypiax.

I want main freeswitch server to tell the Freeswitch/Skype server to use
a dedicated Skype interface(interface1, interface2 etc). What is the
best way to pass this variable?
Some ideas from my side

    * set caller_id_number or caller_id_number_name, as these are
      overwritten by Skype anyway. But this is not a clean solution
    * use another UDP port for each gateway, but this is a huge effort
      if the number of gateways becomes larger
    * set a dedicated sip header for this. Reading sip-header is easy
      (documented) but how to set my own sip header entry in FS?
    * any other idea?


Best regards
Peter
