-------------------------------------------------------------------

Attached configuration and log files.
Softphone A is the endpoint 2000 in pjsip_A.conf
Softphone B is the endpoint 1000 in pjsip_B.conf
Asterisk A is the endpoint peer_1_238 in pjsip_B.conf
Asterisk B is the endpoint peer_2_178 in pjsip_A.conf
full_corrupt is the debug log file.

I managed to "fix" the issue by modifying rtp_engine.c, res_pjsip_sdp_rtp.c and res_rtp_asterisk.c. The attached full_good is the log file after this fix. I'll put my patch up into the review board.

>    Affects Versions: 13.0.0

> Setup:
> I have two Asterisks registered to one another via PJSIP using only "slin" codec.   One PhonerLite softphone A is registered to Asterisk A using "ulaw" codec. Another softphone B is registered to Asterisk B using "ulaw" codec. Note: PhonerLite doesn't support slinear codec.
> Test:
> Softphone A dials an extension into Asterisk A, which will dial another extension into Asterisk B, which eventually dials Softphone B. The voice coming out from Softphone B is corrupted.
