[mod_sofia] Update Polycom UA to recognize new Poly phones
We observed that the new Poly phones (formerly known as Polycom) were not getting sent a SIP UPDATE in certain circumstances (example: retrieving a parked call, and therefore, Caller ID would not show the parked caller). I renamed Polycom to Poly which will catch all Poly AND Polycom UA's. I also added Acrobits, and Ringotel to extend such functionality to those UA's. There were also other minor compatibility issues with the new Poly phones which have been resolved with tweaking the UA recognition on the code.

mahald 1cabda64e2 resolve [Core] add channel var rtp_2833_payload to overwrite rfc2833-pt in sip profile
The DTMF transmission for bridged calls has been problematic for some time now, particularly when the setting "bypass_media_after_bridge=true" is used. This issue arises when the destination PBX utilizes a different PT value for RFC2833 than what is configured in the sofia profile.

To address this challenge, we have implemented a workaround that involves parsing the PT from the switch_r_sdp on the A leg and using a profile with the same value set as rfc2833-pt. For example, if the PT value is 101 on the A-Leg, we use the profile "sofia/outbound101", and if it is 103, we use "sofia/outbound103". This workaround has effectively resolved our DTMF transmission issues.

However, this solution requires extensive configuration and coding on our end, which some customers may not find favorable. Additionally, each profile must utilize a different source UDP Port, further complicating the matter.

It would be beneficial if there was a channel variable for "rtp_2833_payload" that takes precedence over the profile setting when it is set.
