[Linphone-users] Crash on Windows Phone - handling of the plus sign on international numbers

[linphone]

Version of the app : 1.0.4---------------------------------------------
Type: UnhandledException
Message: The remote procedure call failed. (Exception from HRESULT: 
0x800706BE)

A) To reproduce the above:
1. Tap the history button, select a number in the international format 
(i.e. with a leading plus sign and country code)
=> The number is taken over to the dialing window (as sip: 
address@hidden), without the leading plus sign, but a space before 
the number.

2. Tap the call button
=> Crash

Same issue occurs if one manually adds the plus sign to the number 
before calling, keeping the space in place. It's only when one removes 
the space before the added plus sign that the calling works correctly.


B) Another issue is that the number manually fixed as above (i.e. 
sip:address@hidden) does not get recognized as a known number (i.e. one 
that exists in the address book) upon calling. One the other hand, if 
one removes the plus sign, the number does get recognized, but the 
called number is incorrect.


C) When, instead of the call history, one selects a number with a 
leading plus sign from the address book, the number gets taken over to 
the calling screen without the plus sign, which results in a wrong 
number. One needs to manually prepend the plus sign, to be able to call 
the correct number.

P.S.: It looks like some work on this has been done in 
https://github.com/BelledonneCommunications/linphone-wp/commit/e126cefba5e55ed7d6c7f9fd1f90e0f66e628350. 
But WP's app store still provides the version 1.0.4.
