Zoiper sends 101 code, which seems to be not recognized by FS

absolute_codec_string is set to speex@8000h@20i,SILK@8000h@20i,G729,GSM,SILK@12000h@20i,PCMA,PCMU

Still no success

Since the codec is in the dynamic range the payload number is of little to no value the codec name is then used to compare.  So could you provide some details of what you think is wrong?

Hi All,

I have problem with getting Zoiper with enabled codec speex/8000 working with FS. I saw some discussions about this problem before, but none of them ended with working solution.

Maybe these days some of you can share some hints how to hack this

Problem is that Zoiper sends SDP payload type 110 for speex/8000, but FS expects other type for that codec. 

I tried to rewrite SDP on OpenSIPS proxy that sits between end users and FS box, and then later rewrite replies with SDP payload generated by FS to 110 code, but calls always end-up with codec negotiation failure

And yes, I know that zoiper is broken, please don't paste RFC here :) 

It gets very popular on mobile devices and I'm forced to provide support for it, even if its broken
