Hello, when calling from Fritzbox to a Snom Phone , sound is fine. But when calling an internal Freeswitch number (conference, mailbox) i hear a very choppy voice coming from the fritzbox side. I think it may have to do with the ptime 20msec/30msec.
Example: When calling from the fritzbox to a voicemail then the annoucement from Freeswitch is choppy (too slow with interrups), but the recorded message is fine. Did anybody experience the same problem? Best regards Peter Here are some SIP messages: U 112.xxx.xx.xxx:5060 -> 182.xxx.xx.xxx:5060 INVITE sip:[email protected] SIP/2.0.
