[Freeswitch-users] Supress Unregister at external gateway

[Peter P GMX]

Thanks for the hint,

we are doing this with SIP SRV records already.
Concerning pause: There is a command to pause the media on a given
channel. Is there another command to stop FS responding on requests?

Best regards
Peter
