Default PSTN gateway codec order

Currently when I dial PSTN access number Sipbroker gateway will setup a call with the following codec order:

Code:
RTP/AVP 0 18 8 111 97 3 4 101

a=rtpmap:0 PCMU/8000
a=rtpmap:18 G729/8000
a=fmtp:18 annexb=no
a=rtpmap:8 PCMA/8000
a=rtpmap:111 G726-32/8000
a=rtpmap:97 iLBC/8000
a=rtpmap:3 GSM/8000
a=rtpmap:4 G723/8000
It will be more logical to make it looking like 0 8 18 111 97 3 4 101,
i.e. puth both PCM codecs first and lower bandwidth codecs after.

This is my real problem. I'm dialing my home VSP using the SIP-code. The SIP account with my home VSP is forwarded permanently to the local PSTN number. As soon as PCMU is not supported by my VSP the call is established with G.729 (according to Sipbroker's preference) while I need G.711A!

Thanks!

Depends on the sponsor. Some numbers we physically host so I have made a change to those numbers.

Please confirm the number you were using and if the order has now changed?

Thanks

Martin,
thank you very much. It works!

I tested with New York number +1-646-291-2168
According to the source IP address it's the same server or gateway which serves Sweden access number. Last time I had a problem with that particular number. Thanks again.
