Hello, when our Freeswitch sends an INVITE to a phone, it only offers speex codec for voice: m=audio 12068 RTP/SAVP 8 0 98 3 18 101 13 a=rtpmap:98 SPEEX/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 When the phone then answers with ACK and OK and sends back it's own codecs during OK, then codecs are negociated to PCMA, which is fine. However our Aastra phones do not like Speex in the INVITE message, so they send back a "Bad request". We have set in vars.xml <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMA,PCMU,G729,GSM,speex@8000h@20i,speex@16000h@20i"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMA,PCMU,G729,GSM,speex@8000h@20i,speex@16000h@20i"/> and the internal profile contains <param name="inbound-codec-prefs" value="PCMA,PCMU,speex,GSM,G729"/> <param name="outbound-codec-prefs" value="PCMA,PCMU,speex,GSM,G729"/> <param name="inbound-codec-negotiation" value="greedy"/> <param name="outbound-codec-negotiation" value="greedy"/> So Speex is not the preferred codec defined. Eeven 'scrooge' did not solve the problem. How can I get rid of this behaviour and force Freeswitch to invite with PCMA? -- With kind regards Peter Steinbach Telefaks Services GmbH Theo-Geisel-Strasse 25 D 61250 Usingen, Germany mailto:lists (att) telefaks.de Internet: www.telefaks.de
